Analysis and Design
Structure charts provide the framework for programmers to code the various
modules of the system by providing all the necessary information about each module
of the system. From here the system analyst takes a backseat and programmer comes
into action. Programmer codes each and every module of the system, which gives
a physical shape to the system.
Coding phase is aimed at converting the design of the system prepared during
the design phase onto the code in a programming language, which performs the tasks
as per the design requirements and is executable by a computer. The programs should
be written such that they are simple, easy to read, understand and modify.
Program should also include comment lines to increase the readability and modifiability
of the program. Tools like flow charts and algorithms are used for coding the
programs. In some cases, this phase may involve installation and modification
of the purchased software packages according to the system requirements.
From here, the system goes for testing.
