Question 31

An organization uses a database management system (DBMS) as a repository for data. The DBMS, in turn, supports a number of end-user developed applications which were created using fourth-generation programming languages. Some of the applications update the database. Which of the following is the most important control related to the integrity of the data in the database?

  1. End users have their read-only applications approved by the information systems department before accessing the database.
  2. Concurrency update controls are in place.
  3. End-user applications are developed on personal computers before being implemented on the mainframe.
  4. A hierarchical database model is adopted so that multiple users can be served at the same time.

Question 32

Which of the following is not a method for implementing a new application system?

  1. Direct cutover.
  2. Parallel.
  3. Pilot.
  4. Test.

Question 33

One change control function that is required in client/server environments, but is not required in mainframe environments, is to ensure that:

  1. Program versions are synchronized across the network.
  2. Emergency move procedures are documented and followed.
  3. Appropriate users are involved in program change testing.
  4. Movement from the test library to the production library is controlled.

Question 34

A key advantage of developing a computer application by using the prototyping approach is that it:

  1. Does not require testing for user acceptance.
  2. Allows applications to be portable across multiple system platforms.
  3. Is less expensive since it is self-documenting.
  4. Better involves users in the design process.

Question 35

Which of the following is a disadvantage of selecting a commercial software package rather than developing an application internally?

  1. Lack of flexibility.
  2. Incompatibility with client/server technology.
  3. Employee resistance to change.
  4. Inadequate technical support.
