Development

Application development is complex, time-consuming and error prone. Highly skilled developers are required.

Modular and subsystem programming code will be accomplished during this stage. Unit testing and module testing are done in this stage by the developers. The design must be translated into a machine-readable form. The development step performs this task. If the design is performed in a detailed manner, Development can be accomplished without much complication. Programming tools like compilers, interpreters, debuggers etc are used to generate the code. Different high level programming languages like C#, C++, C, Java are used for coding. With respect to the type of application, the right programming language is chosen.

The latest developments allow to generate applications straight from the knowledge systems. This approach finds its justification in the use of semantic technologies with substitution of www data with verified production data. The RAD model assumes the use of the RAD tools like VB, VC++, C# etc rather than creating software using conventional third generation programming languages. The RAD model works to reuse existing program components (when possible) or create reusable components (when necessary). In all cases, automated tools are used to facilitate construction of the software.

This is also the phase where the bugs are worked out of the system. A contingency plan is also developed at this point. A contingency plan is an emergency management document. If the power goes out – what happens to the system? What is the back up? How fast can it be brought back up to speed? Again.
