There are a number of advantages to using the web to access an organiza- tion's internal database:

-web browser software is much easier to use than proprietary query tools -the web interface requires few or no changes to the internal database. It costs much less to add a web interface in front of a legacy system than to redesign and rebuild the system to improve user access. Accessing corporate databases through the web is creating new efficiencies, opportunities, and business models

tuples vs key field vs primary key vs foreign key

=Rows =table uniquely identifies each record =unique identifier for all the information in any row of the table =a lookup field to look up data about the supplier of a specific part.

Web beacons

also called web bugs (or simply track- ing files), are tiny software programs that keep a record of users' online click- streams. They report this data back to whomever owns the tracking file invisibly embedded in e-mail messages and web pages that are designed to monitor the behavior of the user

Digital Millennium Copyright Act (DMCA)

also provides some copyright protection. implemented a World Intellectual Prop- erty Organization Treaty that makes it illegal to circumvent technology-based protections of copyrighted materials. Internet service providers (ISPs) are required to take down sites of copyright infringers they are hosting when the ISPs are notified of the problem

Standards and network effects

among manufacturers and widespread consumer acceptance of technology standards.

Portals generate revenue primarily by

attracting very large audiences, charging advertisers for display ad place- ment (similar to traditional newspapers), collecting referral fees for steering customers to other sites, and charging for premium services.

Application controls can be classified`

as (1) input controls, (2) processing controls, and (3) output controls.

The types of information obtainable from data mining include

associations, sequences, classifications, clusters, and forecasts. a; occurrences linked to a single event s: events are linked over time Clustering works in a manner similar to classification when no groups have yet been defined

Behavioral targeting takes place at two levels:

at individual websites or from within apps and on various advertising networks that track users across thou- sands of websites.

Each characteristic or quality describing a particular entity is called an

attribute For example, Student_ID, Course, Date, and Grade are attributes of the entity COURSE.

To gain access to a system, a user must be

authorized and authenticated. Authentication refers to the ability to know that a person is who he or she claims to be.

the leading methodology for understanding the really important information needed by a firm's executives is called the

balanced scorecard method

'retail link system' where it links its suppliers to every one of their stores as soon as cx purchases an item, the suppliers knows to ship replacement

The two most important management challenges in building a successful e-commerce presence are

(1) developing a clear under- standing of your business objectives and (2) knowing how to choose the right technology to achieve those objectives.

Moore's Law and Microprocessing Power

(1) the power of microprocessors doubles every 18 months, (2) comput- ing power doubles every 18 months, and (3) the price of computing falls by half every 18 months. but this expo growth/decline may not be able to con- tinue much longer may reach the physical limits

management information systems (MIS) supports..

+ tries to achieve this broader information systems literacy

how has changes in tech transformed social and busieness practices

-250m+ americans have mobile phones and 195m access the net w their smart phones and tablets -smartphones, social networking, texting, emailing, and webinars have all become essential tools of business -150+ businesses worldwide have internet sites registered for online shopping -businesses are using information technology to sense and respond to rapidly changing demands, reduce inv to lowest possible lvls, and obtain higher levels of operational efficiency.

voyage-estimating system

-An interesting, small, but powerful DSS -calculates financial and technical voy- age details. Financial calculations include ship/time costs (fuel, labor, capi- tal), freight rates for various types of cargo, and port expenses. Technical details include a myriad of factors, such as ship cargo capacity, speed

TLDR on Kroger

-Grocery store of the future -collect data using infrared sensors to make predictions "QueVision" -has cut average wait time 4min -> 30secs -also temperature monitoring system, no longer need employees to manually check and less spoilage -started own online ordering service, pickup w/o leaving car -mobile app -focused on higher cx satisfaction levels

difference betwn electronic business and electronic commerce

-business refers to the use of digital tech and the internet to execute business proceses includes activities for the internal managment and coordination for outsiders -commerce deals with the buying and selling over the internet also activities supporting market transactions like ads, cx support, security

explain the interdependance between a firms information systems and its business capabilities

-changes in strategy, rules, and business processes would require changes in the hardware, software, databases and telecommunications -yet often what the organization would LIKE to do ends up DEPENDING on that their systems permit to do

what are the reasons why collaborations are important today

-changing nature of work [changed from factory manufacturing] -growth of professional work, "interaction" jobs [pro jobs req lots of info and opinions, lots of ppl with special expertise] -changing organization of the firm [no longer organized in a hierarchical fashion, today work is done in group and teams] -changing scope of the firm [from single location to multiple, often global] -emphasis on innovation [strong collab practices and technologies are believed to increase the rate of innovation] -changing culture of work [diverse teams instead of solo work is the standard]

TL;DR on ABB

-company w lots of employees all over world -used to have intranet but found that it lacked tools to share ideas and work efficiency -then replaced with Inside+, which include microsoft yammer, office 365, and sharepoint -this made them become "social", able to collab, discover ppl, etc -but tech alone did not solve ABB's problem, had to include changes to mangement (develop strats ans goals) and organization (change processes and company culture) illustrates how much organizations today rely on informa- tion systems to improve their performance and remain competitive.

what are other alternatives to enterprise applications

-enterprise often costly and difficult to implement -use intra and extranets

systems for business intelligence

-focused on delivery of info to support desicison making -3 parts to business intel 1]management info systems [mis] -for middle management -reports on preformance -answers to routine questions -report on the company's basic operations using data supplied by transaction processing systems 2]decision support systems [dss] -focus on problems that are unique and rapidly changing -uses internal info like [mis] and [tps] and also external info like stock market -"what rate should we use to increase profits by 60%?" 3]executive support systems (ess) -help make stratgic and long term decisions -non routine, requires evaluation -designed to incorporate data about external events

explain the concept of complementary assets when it comes to reaping and sowing results with information systems

-you might invest a lot and receive a lot but not all businesses face this -suggests that investment itself does not guarantee good returns -this variation is due to complementary assets (those assets req to derive value from a primary investment) -research indicates that firms that support their investments like new business modles, processes, behaviour, culture, or training will receive superior returns

telepresence

. High-end videoconferencing systems feature telepresence technology, an integrated audio and visual environment that allows a person to give the appearance of being present at a location other than his or her true physical location

In a legal action, a firm is obligated to respond to a

/discovery request for access to information that may be used as evidence, and the company is required by law to produce those data.

contemporary approaches to information systems

1- technical approach emphasize math models to study the systems and also the physical tech establish theories of computability 2- behavioral approach long term issues that arise like integration, design, implementation how systems effect people but does NOT ignore technology just concentrates on changes in attitude and behaviour

the four layers of the TCP/IP reference model for communications.

1. Application layer. ----enables client application programs to access the other layers and defines the protocols 2. Transport layer. ----providing the Application layer with communication and packet services. tcp used here 3. Internet layer. ----addressing, routing, and packaging data packets ip used here 4. Network Interface layer ----responsible for placing packets on and receiving them from the network medium

levels in a firm

behaviorally targeted ads are generally ___ times more likely to produce a consumer response than a randomly chosen

10

businesses invest in information systems to achieve what 6 strategic objectives?

1] operational excellence -info systems and tech are some of the most important tools to increasing lvls of efficiency and productivity 2] new prod/ser and business models -tech r major enabling tool -b.model: describes how a company produces, delivers, and sells to create wealth 3] cx and supplier intimacy -knows cx well = serves good = more purchases -intimacy w suppliers = lower costs 4] improved decision making -before they operated with an 'info fog bank' where managers rely on forecasts and luck, now can use real-time data 5] competitive advantage -any points from 1~4 already allows you to be superior 6] survival -sometimes these changes are 'necessities' and u need to follow the trends, redundant old stuff not effective anymore

information systems literacy vs computer literacy

1] the understanding of the management and organizational dimensions of systems as well as the technical dimensions of systems = broader under- standing of information systems, 2] focuses on primarily on knowledge of information technology

the 3 interrelated changes in the technology area

1] the wide spread adopting of the mobile computing platform 2] growing use of 'big data' and data from internet-linked networks of sensors aka internet-of-things [IoT] 3] the growth in 'cloud computing' where more business softwares are running over the internet (major business applications are delivered online now) (performing tasks on the internet that was traditionally done on corporate computers)

the 2 different management groups

1] transaction processing systems (tps) 2] systems for business intelligence

Today wireless car- riers offer

3G networks, with transmission speeds ranging from 144 Kbps for mobile users + 2 Mbps for stationary users offer fair transmission speeds for e-mail, browsing the web, and online shopping but are too slow for videos 4G networks have much higher speeds: 100 megabits/second download and 50 megabits upload speed

repetitive stress injury (RSI)

A common occupational disease today is repetitive stress injury (RSI). RSI occurs when muscle groups are forced through repetitive actions often with high-impact loads (such as tennis) or tens of thousands of repetitions under low-impact loads (such as working at a computer keyboard). The incidence of RSI is estimated to be as much as one-third of the labor force and accounts for one-third of all disability cases.

nonobvious relationship awareness (NORA)

A data analysis technology has given both the government and the private sector even more powerful profiling capabilities. NORA can take information about people from many disparate sources, such as employment applications, telephone records, customer listings, and wanted lists, and correlate relationships to find obscure connections that might help identify criminals or terrorists

Declining Communications Costs and the internet

A fourth technology driver transforming IT infrastructure is the rapid decline in the costs of communication and the exponential growth in the size of the Internet To take advantage of the business value associated with the Internet, firms must greatly expand their Internet connections, including wireless connectiv- ity, and greatly expand the power of their client/server networks, desktop cli- ents, and mobile computing devices

Management and Governance FOR IT

A long-standing issue among information system managers and CEOs has been the question of who will control and manage the firm's IT infrastructure.

Alternatively, LANs may use a peer-to-peer architecture--meaning?

A peer-to-peer network treats all proces- sors equally and is used primarily in small networks with 10 or fewer users. The various computers on the network can exchange data by direct access and can share peripheral devices without going through a separate server.

public vs private cloud

A public cloud is owned and maintained by a cloud service provider, such as Amazon Web Services, and made available to the general public A private cloud is operated solely for an organization. It may be managed by the organization or a third party and may be hosted either internally or externally. Companies that want flexible IT resources and a cloud ser- vice model while retaining control over their own IT infrastructure are gravitat- ing toward these private clouds.

The Law of Mass Digital Storage

A second technology driver of IT infrastructure change The amount of digital information is roughly doubling every year Fortunately, the cost of storing digital information is falling at an exponential rate of 100 percent a year.

Software Packages and Enterprise Software

A software package is a prewritten commercially available set of software pro- grams that eliminates the need for a firm to write its own software programs for certain functions, such as payroll processing or order handling. software packages that can support the primary business processes of a firm worldwide from warehousing, customer rela- tionship management, and supply chain

real-time bidding platforms (RTB)

Ad networks create real-time bidding platforms (RTB) where marketers bid in an automated environment for highly targeted slots available from web publishers. ad platforms can predict how many targeted individuals will view the ads, and ad buyers can estimate how much this exposure is worth to them.

information policy

An information policy specifies the organization's rules for sharing, dis- seminating, acquiring, standardizing, classifying, and inventorying informa- tion

Semantic Search vs Social search

Another way for search engines to become more discrimi- nating and helpful is to make search engines capable of understanding what we are really looking for understand human language and behavior Google and other search engine firms are attempting to refine search engine algorithms to capture more of what the user intended vs effort to provide fewer, more relevant, and trustworthy search results based on a person's network of social contacts

In-Memory Computing

Another way of facilitating big data analysis relies primarily on a computer's main memory (RAM) for data storage.thereby eliminating bottlenecks from retrieving

some of the negative social consequences of systems

Balancing Power: Center Versus Periphery -corporate Internet behemoths such as Google, Apple, Yahoo, Amazon, and Microsoft have come to dominate the collection and analysis of personal private information of all citizens Rapidity of Change: Reduced Response Time to Competition -Time-based competition has an ugly side; the business you work for may not have enough time to respond to global competitors and may be wiped out in a year along with your job. -developing a just- in-time society -no benefits or insurance for employees Maintaining Boundaries: Family, Work, and Leisure -The traditional boundaries that separate work from family and just plain leisure have been weakened. -more people are working when traditionally they would have been playing or communicating with family and friends. -extends far beyond the eight-hour day -Extensive Internet and cell phone use, even for entertainment or recreational purposes, takes people away from their family and friends. Dependence and Vulnerability -highly vulnerable if these systems fail Computer Crime and Abuse

A technology called deep packet inspection (DPI) helps solve

Bandwith-consuming applications clog and slow down corporate networks, degrading performance how: examines data files and sorts out low-priority online material while assigning higher priority to business-critical files

Search engine optimization (SEO)

Because search engine marketing is so effective companies seek to opti- mize their websites for search engine recognition is the process of improving the quality and volume of web traffic to a website by employing a series of techniques that help a web- site achieve a higher ranking with the major search engines when certain key- words and phrases are put into the search field

Risk Assessment

Before your company commits resources to security and information sys- tems controls, it must know which assets require protection and the extent to which these assets are vulnerable

In general, courts appear to be following the reasoning of a 1989 case

Brown Bag Software v. Symantec Corp—in which the court dissected the elements of software alleged to be infringing. The court found that similar concept, func- tion, general functional features (e.g., drop-down menus), and colors are not protectable by copyright law

Collaboration vs . Teams

Collaboration can be short-lived, lasting a few minutes, or longer term, depending on the nature of the task Teams have a specific mission that someone in the business assigned to them. Teams have a specific mission that someone in the business assigned to them.

What are the components of IT infrastructure?

Computer Hardware Platforms Operating System Platforms Enterprise Software Applications Data Management and Storage Networking/Telecommunications Platforms Internet Platforms Consulting and System Integration Services

define information technology [IT]

Consists of all the hardware and software that a firm needs in order to achieve business objectives

information vs data

Data are streams of raw facts =before they have been organized and arranged Information is data shaped into meaningful form

There are six elements in this business intelligence environment:

Data from the business environment: deal with both structured and unstructured data from many different sources Business intelligence infrastructure Business analytics toolset: software tools are used to analyze data and produce reports` Managerial users and methods Delivery platform—MIS, DSS, ESS User interface: data visualization tools, such as rich graphs, charts, dashboards, and maps

______ provides insights into corporate data that cannot be obtained with OLAP & why

Data mining by finding hidden patterns and relationships in large databases and inferring rules from them to predict future behavior. rules are used to guide decision making and forecast the effect of those decisions

Data Redundancy vs Inconsistency

Data redundancy is the presence of duplicate data in multiple data files so that the same data are stored in more than one place or location leads to data inconsistency >>may be updated in some sys- tems but not in others

entity-relationship diagram

Database designers document their data model with an entity-relationship diagram The lines connecting the boxes represent relationships that ends in two short marks designates a one-to- one relationship. A line connecting two entities that ends with a crow's foot topped by a short mark indicates a one-to-many relationship.

Candidate Ethical Principles

Do unto others as you would have them do unto you (the Golden Rule) (Immanuel Kant's categorical imperative). Ask yourself, "If everyone did this, could the organization, or society, survive?" slippery slope rule Take the action that achieves the higher or greater value (utilitarian princi- ple) Take the action that produces the least harm or the least potential cost (risk aversion principle) Assume that virtually all tangible and intangible objects are owned by someone else unless there is a specific declaration otherwise. (ethical no-free- lunch rule.)

Text mining

E-mail, memos, call center tran- scripts, survey responses, legal cases, patent descriptions, and service reports are all valuable for finding patterns and trends that will help employees make better business decisions tools are able to extract key elements from unstructured big data sets, discover patterns and relationships, and summarize the information.

Exchanges [Net marketplaces]

Exchanges are independently owned third-party Net marketplaces that con- nect thousands of suppliers and buyers for spot purchasing. Exchanges proliferated during the early years of e-commerce, but many have failed encour- aged competitive bidding that drove prices down and did not offer any long- term relationships

Most American and European privacy law is based on a regime called

Fair Information Practices (FIP) is a set of principles governing the collection and use of information about individ- uals. based on the notion of a mutuality of interest between the record holder and the individual.

If you work in a firm providing financial services, your firm will need to com- ply with

Financial Services Modernization Act of 1999, Gramm-Leach-Bliley Act ensure the security and confidentiality of customer data. Data must be stored on a secure medium, and special security measures must be enforced to protect such data on storage media and during transmittal.

FTC added three practices to its framework for privacy

Firms should adopt privacy by design, building products and services that protect privacy, firms should increase the transparency of their data practices, and firms should require consumer consent and provide clear options to opt out

Hadoop

For handling unstructured and semi-structured data in vast quantities, as well as structured data, organizations are using Hadoop is an open source software framework that enables distributed parallel processing of huge amounts of data across inexpensive computers. It breaks a big data problem down into sub-problems, distributes them among up to thousands of inexpensive computer processing nodes, and then combines the result into a smaller data set that is easier to ana- lyze. Hadoop's non-relational database, provides rapid access to the data stored on HDFS and a transactional platform for running high-scale real-time applications. ex do a search on Google, or connect with a friend on Facebook.

why are some Companies are turning to "NoSQL" non-relational database technologies

For more than 30 years, relational database technology has been the gold stan- dard. Cloud computing, unprecedented data volumes, massive workloads for web services, and the need to store new types of data require database alter- natives to the traditional relational model of organizing data in the form of tables, columns, and rows use a more flexible data model and are designed for managing large data sets across many distributed machines and for easily scaling up or down.

HTML VS XML

HTML is limited to describing how data should be presented in the form of webpages, XML can perform presentation, communication, and storage of data. XML makes it possible for computers to manipulate and interpret their data automatically and perform operations on the data without human intervention. XML provides a standard format for data exchange, enabling web services to pass data from one process to another.

hub & switch

Hubs are simple devices that connect network com- ponents, sending a packet of data to all other connected devices. A switch has more intelligence than a hub and can filter and forward data to a specified des- tination on the network.

the world is about to run out of available IP addresses being replaced by a new version of the IP addressing schema called

IPv6 (Internet Protocol ver- sion 6) quadrillion possible unique addresses.

five-step process Ethical Analysis

Identify and describe the facts clearly Define the conflict Identify the stakeholders Identify the options that you can reasonably take Identify the potential consequences of your options

information policy in a small business vs large

If you are in a small business, the information policy would be established and implemented by the owners or managers. In a large organization, manag- ing and planning for information as a corporate resource often require a formal data administration function.

Micropayment systems

In the sales revenue model of e-comm provide content providers with a cost-effective method for processing high volumes of very small monetary transactions (anywhere from 25 cents to $5.00 per transaction)`

Transaction Fee Revenue Model vs Sales Revenue Model

In the transaction fee revenue model, a company receives a fee for enabling or executing a transaction (eBay provides the market, but gets a small transaction fee if sales) In the sales revenue model, companies derive revenue by selling goods, infor- mation, or services to customers.

Mashups and Apps

Individual users and entire companies mix and match these software components to create their own customized applications and to share information with others. EX: personalized your Facebook -provides more customer value than the original Apps are small specialized software programs (application software) that are designed for mobile devices like smartphones and tablets. -provide a streamlined non-browser pathway for users to perform a number of tasks

Five Moral Dimensions of the Information Age

Information rights Property rights Accountability and control System quality Quality of life [What values should be preserved]

Cloud computing consists of three different types of services:

Infrastructure as a service (IaaS): Customers use processing, storage, networking, and other computing resources from cloud service providers to run their information systems. Software as a service (SaaS): Google Docs, Google Apps, and related software ser- vices for desktop productivity and collaboration Platform as a service (PaaS): where customers can develop their own applications for use within

Every computer on the Internet is assigned a unique

Internet Protocol (IP) address, which currently is a 32-bit number represented by four strings of numbers ranging from 0 to 255 separated by periods

Internet Platforms

Internet platforms include hardware, software, and management services to support a firm's website, including web hosting services, routers, and cabling or wireless equipment.

intranet vs extranet

Intranet- private version of Internet used by organizations to facilitate internal communication but present barriers to external access Extranet- the private intranets that are EXTENDED to users outside of the organization (often used to coordinate activities w other firms)

In addition to firewalls, commercial security vendors now provide

Intrusion detection systems =`feature full-time monitoring tools placed at the most vulnerable points or hot spots of corporate networks to detect and deter intruders continually.

Mainframes--current situation

Mainframes have not disappeared. They continue to be used to reliably and securely handle huge volumes of transactions, for analyzing very large quantities of data, and for handling large workloads in cloud computing cen- ters However, the number of providers has dwindled to one: IBM

social engineering

Malicious intruders seeking system access sometimes trick employees into revealing their passwords by pretending to be legitimate members of the company in need of information

malware

Malicious software programs include a variety of threats such as computer viruses, worms, and Trojan horses

ransomware

Malware /proliferating on both desktop and mobile devices. tries to extort money from users by taking control of their computers or displaying annoying pop-up messages.

behavioral targeting

Many e-commerce marketing firms use refers to tracking the clickstreams (history of clicking behavior) of indi- viduals on thousands of websites to understand their interests and intentions and expose them to advertisements that are uniquely suited to their online behavior.

Telephone service based on Internet technology is more vul- nerable bc

Most Voice over IP (VoIP) traffic over the Internet is not encrypted. Hackers can intercept conversations or shut down voice service by flooding servers supporting VoIP with bogus traffic. does not run over a secure private network.

FTC FIP principles

Notice/awareness (core principle) Choice/consent (core principle) Access/participation Security Enforcement

Online Analytical Processing (OLAP)

OLAP supports multidimensional data analysis, enabling users to view the same data in different ways using multiple dimensions. ex your company sells four different products—nuts, bolts, washers Each aspect of information—product, pricing, cost, region, or time period—represents a different dimension. So, a product manager could use a multidimensional data analysis tool to learn how many washers were sold in the East in June,

The Dark Side of Big Data

Predictive policing =racial profiling. Computerized hiring =is it fair to screen job applicants this way? Targeting financially vulnerable individuals new opportunities for invading your privacy and using informa- tion that could cause you harm.

e-tailers

Online retail stores similar to the typical bricks-and-mortar storefront, except that customers only need to connect to the Internet to check their inventory and place an order. `

Podcasting vs Streaming`

Podcasting is a method of publishing audio or video broadcasts through the Internet, allowing subscribing users to download Streaming is a publishing method for music and video files that flows a continuous stream of content to a user's device without being stored locally on the device

Nevertheless, the government, privacy groups, and the online ad industry are still at loggerheads over two issues

Privacy advocates want both an opt-in pol- icy at all sites and a national Do Not Track list. The industry opposes these moves and continues to insist that an opt-out capability is the only way to avoid tracking

There are six analytic functionalities that BI systems deliver

Production reports Parameterized reports: pivot table to filter data and isolate impacts of parameters Dashboards/scorecards: These are visual tools for presenting Ad hoc query/search/report creation: These allow users to create their own reports based on queries and searches Drill down: This is the ability to move from a high-level summary to a more detailed view. Forecasts, scenarios, models

Internet-based distribu- tors

Providers do not have to be the creators of the content (although sometimes they are, like Disney.com) content produced and created by others. For example, Apple sells music

disintermediation effects on consumers and sellers

Removing layers lowers the final cost to the customer is affecting the market for services. Airlines and hotels operating their own reservation sites online earn more per ticket because they have eliminated travel agents as intermediaries`

Basic Concepts of Ethical choices:

Responsibility, =means that you accept the potential costs, duties, and obligations for the decisions you make. Accountability, =determine who took action and who is responsible. and Liability =is a feature of political systems in which a body of laws is in place that permits individuals to recover the damages done to them

Two methods for encrypting network traffic on the web are

Secure Sockets Layer (SSL) and its successor, Transport Layer Security (TLS) Secure Hypertext Transfer Protocol (S-HTTP) but it is limited to individual messages, whereas SSL and TLS are designed to establish a secure connection between two computers.

Security vs Controls

Security refers to the policies, procedures, and technical mea- sures used to prevent unauthorized access, alteration, theft, or physical damage to information systems. Controls are methods, policies, and organizational pro- cedures that ensure the safety of the organization's assets, the accuracy and reli- ability of its records, and operational adherence to management standards.

types of Net marketplaces

Some sell direct goods and some sell indirect goods. used in a production process, such as sheet steel for auto body production. Indirect goods are all other goods not directly involved in the production process, such as office supplies [New Ways of B2B Buying and Selling]

The most prominent data manipulation language today is

Structured Query Language would employ SQL to retrieve information they needed from the database.

Wi-Fi

The 802.11 set of standards for wireless LANs and wireless Internet access wireless devices communicate with a wired LAN using access points. An access point is a box consisting of a radio receiver/ transmitter and antennas that links to a wired network, router

long tail marketing

The Internet enables this--before : attracting the largest number of consumers with popular hit prod- ucts, whether music, Hollywood movies, books find potential customers inexpensively for products where demand is very low. For instance, the Internet makes it possible to sell independent music profitably to very small audiences.

information asymmetry

The Internet reduces this when one party in a transaction has more information that is impor- tant for the transaction than the other party balanced bargaining power`

seven hardware trends:

The Mobile Digital Platform = alternatives to PCs and larger computers =Wearable computing devices are a recent addition Consumerization of IT and BYOD ="bring your own device" =consumer market spreads into business organizations. =but also business uses of software services Quantum Computing =would gain enormous processing power through this ability to be in multiple states at once, allowing it to solve some scientific and business problems millions of times faster than can be done today Virtualization =accessed in ways that are not restricted by physical configuration or geographic location Cloud Computing =is a model of computing in which computer processing, storage, software, and other services are provided as a shared pool of virtualized resources over a network, primarily the Internet. Green Computing =or green IT, refers to practices and technologies =minimize impact on the environment. High-Performance and Power-Saving Processors =now fea- ture multiple processor cores =more processor cores have been attached for enhanced performance, reduced power consumption, and more efficient simultaneous processing of multiple tasks.

service level agreement (SLA)

The SLA is a formal contract between customers and their service pro- viders that defines the specific responsibilities of the service provider and the level of service expected by the customer. SLAs typically specify the nature and level of services provided, criteria for performance measurement, support options,

Evolution of IT Infrastructure

The five eras are general-purpose mainframe and minicomputer computing =widespread commercial use of mainframe comput- ers =(usually in a cor- porate data center) =most elements of infrastructure provided by a single vendor, the manufacturer of the hardware and the software. =began to change with the introduction of minicomputers =instead of sharing on a single huge mainframe personal computers =The Wintel dominance as a computing platform =Worldwide PC shipments have declined more than 10 percent because of the popularity of tablets and smartphones, but the PC is still a popular tool for business client/server networks = desktop or laptop computers called clients are networked to powerful server computers that provide the client computers with a variety of services and capabilities. =can be one server or multitiered enterprise computing = firms turned to networking standards and software tools that could integrate disparate networks and applications throughout the firm =links different pieces of computer hardware and smaller networks into an enterprise-wide network so that information can flow freely across the organization and cloud and mobile computing. =shared pool of computing resources (computers, storage, applications, and services) over the network, often the Internet = accessed by desktop computers, laptop com- puters, tablets etc

Wired Equivalent Pri- vacy (WEP)

The logical view presents data as they would be per- ceived by end users or business specialists, whereas the physical view shows how data are actually organized and structured on physical storage media.

Relational DBMS

The most popular type of DBMS today Relational databases represent data as two-dimensional tables contains data on an entity and its attributes.

Transmission Speed: "hertz"

The number of cycles per second that can be sent through that medium is measured in hertz 1 cycle, is required to transmit one or several bits

normalization

The process of creating small, stable, yet flexible and adaptive data structures from complex groups of data is called normalization. //to minimize redundant data elements and awkward many- to-many relationships

Data Warehouses and Data Marts [A contemporary infrastructure for business intelligence has an array of tools for obtaining useful information from all the different types of data used by businesses today]

The traditional tool for analyzing corporate data for the past two decades has been the data warehouse. The data originate in many core operational transaction systems The data warehouse makes the data available for anyone to access as needed, but the data cannot be altered. --- they create smaller, decen- tralized warehouses called data marts. A data mart is a subset of a data ware- house in which a summarized or highly focused portion of the organization's data is placed in a separate database for a specific population of users.

investments in information technology are not helpful for all managerial roles why

There are three main reasons: information quality, management filters, and organizational culture -corporate databases and files have varying levels of inaccuracy and incompleteness -Even with timely, accurate information, managers often make bad decisions. Man- agers (like all human beings) absorb information through a series of filters decisions based on intuition, feelings, and the framing of the problem as opposed to empirical data -balancing of the firm's various interest groups rather than the best solution to the problem

Non-relational database manage- ment systems are useful for

They are useful for accelerating simple queries against large volumes of structured and unstructured data, including web, social media, graphics, and other forms of data that are difficult to analyze with traditional SQL- based tools. without requiring tedious, expensive, and time-consuming database mapping.

just what is the responsibility of a producer of computer services—should it withdraw the product that can never be perfect, warn the user, or forget about the risk (let the buyer beware)?

Three principal sources of poor system performance are (1) software bugs and errors, (2) hardware or facility failures caused by natural or other causes, and (3) poor input data quality.

Intellectual property is subject to a vari- ety of protections under three legal traditions:

Trade Secrets =Any intellectual work product -vary from state to state. -protects the actual ideas in a work product, not only their manifestation -The limitation of trade secret protection is that, although virtually all soft- ware programs of any complexity contain unique elements of some sort, it is difficult to prevent the ideas in the work from falling into the public domain when the software is widely distributed Copyright a statutory grant that protects creators of intellectual property from having their work copied by others for any purpose during the life of the author plus an additional 70 years after the author's death - For corporate-owned works, copyright protection lasts for 95 years after their initial creation. -protects against copying entire programs or their parts

safe harbor

Working with the European Commission, the U.S. Department of Commerce developed a safe harbor framework for U.S. firms. A safe harbor is a private, self-regulating policy and enforcement mechanism that meets the objectives of government regulators and legislation but does not involve government regu- lation or enforcement However, in October 2015, Europe's highest court struck down the safe harbor agreement entirely, in large part due to the revelations by Edward Snowden that Facebook had shared personal information on European citizens with the NSA and there- fore violated the terms of the agreement

Client/server computing has largely replaced

about zero (it costs nothing to make a copy of a music file). However, the cost of producing the original first unit is relatively high

In-Memory Computing viability

advances in contemporary com- puter hardware technology that make in-memory processing possible These technologies help companies optimize the use of mem- ory and accelerate processing performance while lowering costs.

most E-commerce companies rely on one, or some combination, of the following six revenue models:

advertising, sales, sub- scription, free/freemium, transaction fee, and affiliate`

When you adopt these BI and BA systems, you are in essence taking in a new partner--why

all BI and BA systems lock the firm into a set of vendors and switching is very costly. Once you train thousands of employees across the world on using a particular set of tools, it is extremely difficult to switch.

The universal technical standards of the Internet and e-commerce [impacts]

bc any computer to link with any other computer regardless of the technology platform each is using greatly lower market entry costs—the cost merchants must pay simply to bring their goods to market. At the same time, for consumers, universal standards reduce search costs—the effort required to find suitable products.

on-demand computing

bc organizations using public clouds do not own the infrastructure, they do not have to make large investments in their own hardware and soft- ware. Instead, they purchase their computing services from remote providers and pay only for the amount of computing power they actually use (utility computing) or are billed on a monthly or annual subscription basis. The term on-demand computing has also been used to describe such services.

technologies that characterize one era may also

be used in another time period for other purposes. For example, some companies still run traditional mainframe systems or use mainframe computers as servers supporting large websites and corporate enterprise applications.

A computer system organizes data in a hierarchy that starts with

bits and bytes and progresses to fields, records, files, and databases' bit = smallest unit of data a computer can handle A group of bits = byte grouping of characters into a word, a group of words, or a complete number = field A group of related fields, such as the student's name = record a group of records of the same type is called a file.

The total amount of digital information that can be transmitted through any telecommunications medium is measured in

bits per second (bps)

Commercial database vendors have developed specialized high-speed analytic platforms using

Making a decision is a multistep process.described four differ- ent stages in decision making:

intelligence, design, choice, and implementation Intelligence consists of discovering, identifying, and understanding the problems occurring in the organization—why a problem exists, where, and what effects it is having on the firm. Design involves identifying and exploring various solutions to the problem. Choice consists of choosing among solution alternatives. Implementation involves making the chosen alternative work and continu- ing to monitor how well the solution is working.
