In addition to deploying business intelligence (BI) systems, companies may also perform other actions to counter business pressures, such as improving customer service and entering business alliances. (T/F)

answer

True

question

The use of dashboards and data visualizations is seldom effective in finding efficiencies in organizations, as demonstrated by the Seattle Children's Hospital Case Study. (T/F)

answer

False

question

answer

True

question

Once a data warehouse is in place, the general process of intelligence creation begins with

answer

identifying and prioritizing specific BI projects

question

The term intelligence in a BI context is used to describe clandestine operations dedicated to stealing corporate secrets, in the manner of the government's CIA and other covert agencies. (T/F)

answer

False That's espionage. BI intelligence refers to how modern companies ethically and legally organize themselves to glean as much as they can from customers, their business environment, their stakeholders, their business processes, their competitors, and other such sources.

question

Information systems that support such transactions as ATM withdrawals, bank deposits, and cash register scans at the grocery store represent transaction processing, one of the critical components of BI. (T/F)

answer

False BI is not transaction processing. Those transaction processing systems are involved in handling updates to operational databases. OLTP (Online Transaction Processing) systems handle a company's routine business.

question

Actionable intelligence is the primary goal of modern-day Business Intelligence (BI) systems vs. historical reporting that characterized Management Information Systems (MIS). (T/F)

The very design that makes an OLTP system efficient for transaction processing makes it inefficient for what? a) end-user ad hoc reports, queries, and analysis b) transaction processing systems that constantly update operational databases c) the collection of reputable sources of intelligence d) transactions such as ATM withdrawals, where we need to reduce a bank balance accordingly

answer

end-user ad hoc reports, queries, and analysis

question

One of the four components of BI systems, business performance management, is a collection of source data in the data warehouse. (T/F)

answer

False A BI system has four components: (1) a data warehouse, with its source data; (2) business analytics, a collection of tools for maipulating, mining, and analyzing the data in the DW; (3) business performance management (BPM) for monitoring and analyzing performance; (4) and a user interface (e.g. a dashboard)

question

If a company's strategy is properly aligned with DW and BI initiatives, and if the company's IS organization can be made capable of playing its role in such a project, and if the requisite user community is in place and has the proper motivation, then a) it is no longer necessary to start BI within the company. b) it is wise to start BI and establish a BI Competency Center (BICC) within the company. c) the organization is ready for the introduction of new data-generating technologies, such as radio-frequency identification (RFID). d) business leaders are required to document their business processes and to sign off on the legitimacy of the information they rely on.

answer

it is wise to start BI and establish a BI Competency Center (BICC) within the company

answer

True

question

Organizations counter the pressures they experience in their business environments in multiple ways. Which of the following is NOT an effective way to counter these pressures? a) reactive actions b) anticipative actions c) adaptive actions d) retroactive actions

Traditional BI systems use a large volume of static data that has been extracted, cleansed, and loaded into a data warehouse to produce reports and analyses. (T/F)

answer

True

question

The two critical partnerships required for BI governance are (a) a partnership between functional area users and/or product/service area employees, and (b) a partnership between representatives of the marketing and vendor sides. (T/F)

answer

False The two critical partnerships required for BI governance are (a) a partnership between functional area HEADS and/or product/service area LEADERS (middles), and (b) a partnership between potential customers and providers (representatives of the business and IT sides).

question

CH2 Organizations seldom devote a lot of effort to creating metadata because it is not important for the effective use of data warehouses. (T/F)

answer

False

question

CH2 Because of performance and data quality issues, most experts agree that the federated architecture should supplement data warehouses, not replace them. (T/F)

answer

True

question

CH2 Data warehouse administrators (DWAs) do not need strong business insight since they only handle the technical aspect of the infrastructure. (T/F)

answer

False

question

CH2 OLTP systems are designed to handle ad hoc analysis and complex queries that deal with many data items. (T/F)

answer

False

question

CH2 OLTP databases are optimized for output (querying/asking questions of the data) and data warehouses are optimized for input (getting new or updated data into the database). (T/F)

answer

False

question

Ch2 Operational or transaction databases are product oriented, handling transactions that update the database. In contrast, data warehouses are

answer

subject oriented and nonvolatile

question

Subject oriented databases for data warehousing are organized by detailed subjects such as disk drives, computers, and networks (T/F)

answer

false

question

Data warehouses are subsets of data marts. (T/F)

answer

false

question

One way an operational data store differs from a data warehouse is the recency of their data. (T/F)

question

Computerized support is only used for organizational decisions that are responses to external pressures, not for taking advantage of opportunities. (T/F)

answer

False The Business Pressures-Response-Support Model has three components: business pressures that result from today's business climate; responses (actions taken) by companies to counter the pressures or to take advantage of the opportunities available; and computerized support that facilitates the monitoring of the environment and enhances the response actions taken by the organizations.
