Exam 20: Systems Operations and Support

Test data can be automatically captured using a software-testing tool. As users enter test data. That data is recorded in a special type of repository as a _________________________.

System enhancement typically involves the following tasks:

The systems analyst is generally on call to assist users with the day-to-day use of specific applications. In mission-critical applications, the analyst must be on call day and night.

_____________________________ ensures that the entire application, of which the modified program was a part, still works. Again, test data and current performance are used here.

Which kind of program restructuring is done to eliminate control flow knots and reduce cycle complexity?

___________________________________ is where software defects or bugs that were not detected during systems testing are corrected.

Usually the original programmer of the software is the person making the changes.

______________________________ is a process whereby a librarian (usually software based) keeps track of changes made to programs. This allows recovery of prior versions of the programs if new versions cause unexpected problems. It allows users to return to a previously accepted version of the system.

________________________________ is performed when new requirements (business or technology) must be added to the system.

Code slicing cuts out a piece of a program to create a separate program or subprogram.

The on-going maintenance of a system(s) after it has been placed into operation, including program maintenance and system improvements is called:

Regression testing extrapolates the impact of the changes on program and application throughput and response time from the before and after results using the test data.

________________________________ is the number of unique paths through a program. Ideally, the fewer, the better.

The central repository stores the actual application programs that have been placed into production.

Some system enhancements can be accomplished quickly by writing new simple programs or making very simple changes to existing programs.

The central repository stores all system models and detailed specifications.

Systems operation and support occur in parallel.

____________________________________ are mathematically proven measurements of software quality and productivity.

Systems support is the on-going technical support for users, as well as the maintenance required to fix any errors, omissions or new requirements that may arise.

The first task of the systems analyst or programmer when working with a program bug is to validate the problem.
