Understanding The Features Of RAD Rapid Application Development
One of the vital parts of any computer system is the software. This is what is used in implementing the applications of the computing process. In fact the development of this particular component requires a numbers of things and will generally follow certain laid down methods. Such methodologies include the RAD Rapid Application Development an approach that can be used to deliver software quickly.
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.
Most importantly for this method is the underlying proposition that faster is better. Therefore the time boxes here are a vital feature within the methodology because through them every stage can be strictly scheduled. Furthermore the deliverables that are time boxed must be accomplished without regard for finer detail. In this way the rapidity aspect is enhanced. Generally this will be implemented throughout the main stages of this methodology including the business process and data modeling application generation which also includes the testing and turnover.
Generally each of these steps has a unique deliverable associated with it. All these deliverables are finally integrated and tested on a global scale to turnover the complete product. The testing process is carried out at two levels that include the unit and system levels. Primarily the business model step includes a general description of such a current business functions.
This includes the description of such business flows defining the current system. Basing on these findings and the flaws in the current system the proposed system will be derived. Generally the requirement elicitation involves both the user and developer. The data modeling step basically defines the data objects which are significant components of this proposed system.
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
