Software is a fundamental part of any computer system. Generally this component is the one that implements all the applications in the computing process. The development of such software entails a disciplined approach that may be accomplished in a number of ways. RAD Rapid Application Development is one such way that is considered as a software production methodology.
Generally this approach is distinct in that it heavily relies on modeling to quickly implement the required software products. Such models or prototypes as they are also known will represent the actual and proposed systems. This offers clarity for both the developer and user of such a system who can understand better the processes when they are prototyped. Moreover the process is iterative in nature.
These iterations give the user and developer an opportunity to closely liaise in order to clearly represent the functional components of the project. Generally this methodology compromises functionality and performance. This is exchanged for a faster development process. In fact the phases within such a process are time-boxed. This involves a typical assignment of definite time frames in which each phase must be accomplished.
Basically the time in such an approach is of more essence than the quality of the product. The methodology typically follows four main steps and characteristically each of these steps has a definite deliverable. Furthermore every step is assigned a time box that must be strictly implemented. Therefore in this way a systematic approach is established basing on this premise.
Generally faster is better according to this technique. Therefore the activities within this methodology must be executed within the particular time boxes. This ensures the rapidity of such a process. Such a procedure is regardless of the quality of these products or deliverables from every stage. This approach proposes a number of main steps. These include business data and process modeling application generation as well as testing and turnover.
Moreover at each of these stages is a deliverable that integrates with others to finally produce the system. Therefore unit and system tests are significant in ascertaining the working of the product prior to and after the integration. Apparently within the first stage of business modeling the description of business functions is achieved.
This entails a collection of business flows describing the current system. Once this has been accomplished then a proposed system can be derived. This is after an assessment of these shortcomings of the current system. This can be achieved through the data modeling process. Within this stage the data objects must be well defined.
The procedures will eventually be modeled at the process model stage. In this way the identified data objects can be utilized in the proposed system framework which is generally the software. Therefore the data business and process models can be incorporated into such an application at the application generation step. Often times the computer aided software engineering (CASE) tools can be applied at this point to expediently generate the prototype based on certain requirements. Ultimately RAD Rapid Application Development includes various aspects that can ensure faster delivery of any software product
