Rapid Application Development (RAD) is an incremental software development process model that emphasises a very short development cycle [typically 60-90 days].
The RAD model, is a very high-speed adaptation of the waterfall model, where the result of each cycle a fully functional system.
The information flow among business functions is modeled in a way that answers the following questions:
What information drives the business process?
What information is generated?
Who generates it?
Where does the information go?
Who processes it?
The information flow defined as part of the business modeling phase is refined into a set of data objects that are needed to support the business. The characteristics (called attributes) of each object are identified and the relationships between these objects are defined.
The data objects defined in the data-modeling phase are transformed to achieve the information flow necessary to implement a business function. Processing descriptions are created for adding, modifying, deleting, or retrieving a data object.
RAD assumes the use of the RAD fourth generation techniques and tools like VB, VC++, Delphi etc rather than creating software using conventional third generation programming languages. The RAD 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.
