Question 1 :
Business Intelligence (BI) systems do not obtain data from operational databases.
Question 2 :
Data Mining uses simple arithmetic techniques such as sums, averages, and groupings to perform what-if analyses, to make predictions, and to facilitate decision making.
Question 3 :
A data warehouse is a database system that is optimized for operational transaction processing.
Question 4 :
Business Intelligence (BI) systems fall into two broad categories: reporting and data warehousing.
Question 5 :
Most operational databases can be used for many BI applications.
Question 6 :
The data warehouse DBMS needs to be the same DBMS used for the operational database.
Question 7 :
RFM analysis is a BI reporting system.
Question 8 :
In a common form of RFM analysis, customers are sorted in five groups and given a score of 1 to 5 depending on their group.
Question 9 :
Report types include static, dynamic, query and OLAP.
Question 10 :
OLAP uses measures, dimensions and associations.
Question 11 :
In unsupervised data mining, explanations are created after patterns are found.
Question 12 :

Question 13 :
BI reporting systems summarize the current status of business activities in order to predict future activities.
Question 14 :

Question 16 :
Formatting the report is part of authoring a report.
Question 17 :
Market basket analysis primarily uses the technique of conditional probabilities.
Question 18 :
A data mart is a collection of data that, while smaller than a data warehouse, still addresses the entire business.
