Discuss the importance of the role of the database administrator. In the flat-file environment, why is such a role not necessary? What tasks does the DBA perform?
Which statement is NOT true? a. Drill-down capability is an OLAP feature of data mining tools available to the user. b. The data warehouse should be separate from operational systems. c. Denormalization of data involves dividing the data into very small tables that support detailed analysis. d. Some decisions supported by a data warehouse are not fundamentally different from those that are supported by traditional databases. e. Data cleansing involves transforming data into standard business terms with standard data values.

The database approach has several unique characteristics not found in traditional (flat-file) systems. Which of the following statements does not apply to the database model? a. Database systems have data independence; that is, the data and the programs are maintained separately except during processing. b. Database systems contain a data-definition language that helps describe each schema and subschema. c. The database administrator is the part of the software package that instructs the operating aspects of the program when data are retrieved. d. A primary goal of database systems is to minimize data redundancy. e. Database systems provide increased accessibility to data and flexibility in its usage.

Some people believe database technology may eliminate the need for double-entry accounting. This creates three possibilities: (1) the double-entry model will be abandoned; (2) the double-entry model will not be used directly, but an external-level schema based on the double-entry model will be defined for accountants’ use; or (3) the double-entry model will be retained in database systems. Which alternative do you think is most likely to occur? Why?
Which of the following is a disadvantage of distributed data processing? a. End-user involvement in systems operation is decreased. b. Disruptions due to mainframe failures are increased. c. The potential for hardware and software incompatibility across the organization isincreased. d. The time between project request and completion is increased. e. All of the above are disadvantages.
Which statement is NOT true?a. In a typical two-tier client-server architecture, the server handles both application and database duties.b. Client computers are responsible for presenting data to the user and passing user input back to the server.c. Two-tier architecture is for local area network applications where the demand on the server is restricted to a relatively small population of users.d. The database and application functions are separated in the three-tier model. e. In three-tier client-server architectures, one tier is for user presentation, one is for database and applications access, and the third is for Internet access.
