MIS CH9
functions of a BI server
-a webserver application created for publishing of business intelligence -maintains metadata about authorized allocation of BI results to users. Serve tracks what results are available, what users are authorized to view those results, and provided results to authorized users. It adjusts allocations as available results change and users come and go
unsupervised data mining
-analysts do not create a model or hypothesis before running the analysis - uses cluster analysis
Hadoop
-open source program supported by Apache Foundation2 -manages thousands of computers -implements Map Reduce (written in Java) -Pig: query language -deep technical skills are needed to run and use Hadoop
4 tasks used in business intelligence
-project management -problem solving -deciding -informing
reporting, data mining, and big data
3 categories of BI analysis
data warehouse
A ________ is a facility for managing an organization's business intelligence data. a. data warehouse b. data room c. datasheet d. data space
how do BI systems work?
Acquire data, Perform data, and Publish results
supervised data mining
In the case of ________, data miners develop models prior to conducting analyses and then apply statistical techniques to data to estimate parameters of the models. a. unsupervised data mining b. pull publishing techniques c. supervised data mining d. push publishing techniques
reporting
The goal of ________, a type of business intelligence analysis, is to create information about past performance. a. reporting b. data mining c. BigData d. push publishing
data warehouse
Users in a data mart obtain data that pertain to a particular business function from a ________. a. data room b. data center c. data warehouse d. datasheet
Business intelligence systems analyze an organization's past performance to make predictions
Which of the following statements is true of business intelligence (BI) systems? a. Business intelligence systems analyze an organization's past performance to make predictions. b. Business intelligence systems are primarily used for developing software systems and data mining applications. c. The software component of a business intelligence system is called an intelligence database. d. The four standard components of business intelligence systems are software, procedures, applications, and programs.
static reports
________ are business intelligence documents that are fixed at the time of creation and do not change. a. Static reports b. Third-party cookies c. Exception reports d. Subscriptions
hadoop
________ is an open-source program supported by the Apache Foundation that manages thousands of computers and implements MapReduce. a. BigData b. Linux c. Apache Wave d. Hadoop
cluster analysis
________ is an unsupervised data mining technique in which statistical techniques identify groups of entities that have similar characteristics. a. Cloud computing b. Content indexing c. Cluster analysis d. Regression analysis
granularity
________ refers to the level of detail represented by data. a. Aggregation b. Granularity c. Abstraction d. Dimensionality
data mining
________ techniques emerged from the combined discipline of statistics, mathematics, artificial intelligence, and machine-learning. a. Data mining b. Pull publishing c. Push publishing d. Exception reporting
data mart
a data collection, smaller than a data warehouse, that addresses the needs of a particular department or functional area of the business
data warehouse
a facility for managing an organization's BI data. Functions are to: obtain data, cleanse data, organize& relate data, and catalog data
regression analysis
a type of supervised data mining that estimates the values of parameters in a linear equation; used to determine the relative influences of variables on an outcome and also to predict future values of that outcome
static reports
are BI documents that are fixed at the time of creation and do not change
dynamic reports
are BI documents that are updated at the time they are released
BI systems
are information systems that process operational and other data to analyze past performance and to make predictions. The patterns, relationships, and trends identified by BI systems are called business intelligence
exception reports
are reports produced when something out of predefined bounds occur
supervised data mining
data miners develop a model prior to the analysis and apply statistical techniques to data to estimate parameters of the model -uses regression analysis
reporting
goal of _______: create information about past performance
inherent processes
predesigned procedures for using software products; they solve organizations from expensive and time consuming business process reengineering
cluster analysis
statistical techniques identify groups of entities that have similar characteristics. A common use for this is to find groups of similar customers from customer order and demographic data
data mining
the application of statistical techniques to find patterns and relationships among data for classification and prediction
granularity
the level of detail in data.
BI analysis
the process of creating business intelligence
characteristics of Big Data
volume, velocity, and variety force use of Map Reduce techniques. Some applications use reporting and data mining as well
