Object-oriented Programming

Notes software system. It also includes testing the software. The key question around which this phase
revolves is – How should the problem be solved?
The first step is to determine how the output is to be produced and in what format. Samples of
the output (and input) are outlined.
Second, input data and master files (data base) have to be designed to generate the required
output. The operational (processing) phase are handled through program construction and
testing, including a list of the programs needed to meet the software objectives and complete
documentation.
Finally, details related to justification of the system and an estimate of the impact of the software
on the user are documented and evaluated before it is implemented.

Implementation

This phase is primarily concerned with coding the software design into an appropriate
programming language; testing the programs and installing the software. User training, site
preparation, and data migration are other important issues in this phase.

Maintenance

Change is inevitable. Software serving the users’ needs in the past may become less useful or
sometimes useless in the changed environment. Users’ priorities, changes in organizational
requirements, or environmental factors may call for software enhancements. A bank, for instance,
may decided to increase its service charges for checking accounts from ` 3.00 to ` 450 for a
minimum balance of ` 3,000. In this phase the software is continuously evaluated and modified
to suit the changes as they occur.
