Some consider it noble to have a method; others consider it noble not to have a method.
The process of writing the software itself involves the planning required for developing the product.
Rapid Application Development focuses on gathering customer requirements through workshops or focus groups, early testing of the prototypes by the customer using iterative concept, reuse of the existing prototypes componentscontinuous integration and rapid delivery.
Rapid application development is a software development methodology that uses minimal planning in favor of rapid prototyping. A prototype is a working model that is functionally equivalent to a Rad rapid application diagram of the product.
In the RAD model, the functional modules are developed in parallel as prototypes and are integrated to make the complete product for faster product delivery. Since there is no detailed preplanning, it makes it easier to incorporate the changes within the development process.
So you want to start developing your very first web application?You want to know how you can start quickly and develop your first web application? Well here is the good news, you are at the right place. The RAD Studio IDE speeds coding so developers can focus on framework design, code logic, and algorithms while rapidly finding the information they . The systems development life cycle (SDLC), also referred to as the application development life-cycle, is a term used in systems engineering, information systems and software engineering to describe a process for planning, creating, testing, and deploying an information system. The systems development lifecycle concept applies to a .
RAD projects follow iterative and incremental model and have small teams comprising of developers, domain experts, customer representatives and other IT resources working progressively on their component or prototype.
The most important aspect for this model to be successful is to make sure that the prototypes developed are reusable.
RAD Model Design RAD model distributes the analysis, design, build and test phases into a series of short, iterative development cycles. A complete business analysis is performed to find the vital information for business, how it can be obtained, how and when is the information processed and what are the factors driving successful flow of information.
Data Modeling The information gathered in the Business Modeling phase is reviewed and analyzed to form sets of data objects vital for the business.
The attributes of all data sets is identified and defined. The relation between these data objects are established and defined in detail in relevance to the business model. Process Modeling The data object sets defined in the Data Modeling phase are converted to establish the business information flow needed to achieve specific business objectives as per the business model.
The process model for any changes or enhancements to the data object sets is defined in this phase. Process descriptions for adding, deleting, retrieving or modifying a data object are given.
Application Generation The actual system is built and coding is done by using automation tools to convert process and data models into actual prototypes. Testing and Turnover The overall testing time is reduced in the RAD model as the prototypes are independently tested during every iteration.
However, the data flow and the interfaces between all the components need to be thoroughly tested with complete test coverage. Since most of the programming components have already been tested, it reduces the risk of any major issues.
The following illustration describes the RAD Model in detail. The customer may need some changes after he gets to see the software. However, the change process is quite rigid and it may not be feasible to incorporate major changes in the product in the traditional SDLC.
The RAD model focuses on iterative and incremental delivery of working models to the customer. This results in rapid delivery to the customer and customer involvement during the complete development cycle of product reducing the risk of non-conformance with the actual user requirements.
If the project cannot be broken into modules, RAD may fail. It should be used if there is a high availability of designers for modeling.
It should be used only if the budget permits use of automated code generating tools.View and Download RAD Data Communications Megaplex installation and operation manual online. Modular Integrated Access Multiplexers. Megaplex Multiplexer pdf manual download.
