Exam 20: Systems Operations and Support

_______________________________ translates the code from one language to another. Typically this translation is from one language version to another.

When after a system crash, transactions must be recovered that occurred between the last backup and the database's recovery, it is called a:

________________________ factors out existing, redundant code into subprograms that are easier to maintain.

Systems operation 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 __________________________ includes all the actual data created and maintained by production application programs. This includes conventional files, relational databases, data warehouses and any object databases.

Before making changes in a program to fix a bug, the analyst should ________________ the program to establish a baseline against which the modified programs and applications can later be measured.

________________________ is performed when a system failure that may result in a program "crash" and/or loss of data occurs. Human error or a hardware or software failure may have caused the error condition. The systems analyst or technical support specialists may be called upon to restore a system's files and databases and to restart the system.

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

Which of the following ensures that the stand-alone program not only fixes the bug, but does so without side effects?

When after a system crash, partially completed transactions must be undone, it is called a:

System testing ensures that the stand-alone program not only fixes the bug, but does so without side effects.

Code slicing is relatively easy to do.

In most installations a software-based librarian will track changes to stored programs and maintain several previous versions of the programs.

The four types of systems support activities are building and testing networks and databases, preparing the conversion plan, installing databases, and training users.

Unit testing ensures that the entire application, of which the modified program was a part, still works.

Version control is the process whereby a librarian (usually software-based) keeps track of changes made to programs thus allowing recovery of prior versions of the programs in the event that new versions cause unexpected problems.

Which of the following is NOT a support activity?

Where are system models and specifications stored?

___________________________ is the ongoing technical support for users, as well as the maintenance to fix any errors, omissions, or new requirements that may arise.

____________________________ ensures that the stand-alone program fixes the bug without undesirable side effects to the program. The test data and current performance you recovered, created, edited or generated when the programs were benchmarked are used here.
