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
