The Rapid Application Development Platform consists of the following phases that encompass analysis, design, building, and final testing.
Business Modeling: In this stage of the RAD software, the necessary information is gathered from a variety of business-related sources. The design team collects pertinent data from the company including specifics related to the market and business objectives. Information gained in this Rapid Application Development phase is then streamlined to shape a usable model. This model provides the basic framework for the functioning of the Rapid Web Application Development.
Data Modeling: In this stage of the Rapid Web Application Development, the information collected during Business Modeling is analyzed to extract usable parameters. The information is categorized according to the requirements of various components of the application. Every category is closely scrutinized for accuracy. The suitability of these datasets with the larger objectives outlined in the Business Modeling stage is also assessed in this step of the RAD software.
Process Modeling: The datasets established in the Data Modeling phase of the Rapid Application Development Platform are converted to extract a process. This process would outline the progression of the actual application development. This stage of the RAD software also serves as a further level of refinement to the business information flow from the first stage. Any changes to the data objects sets can be defined. Methods to add, delete, retrieve and modify data are clearly determined and finalized.
Application Generation: In this phase of the Rapid Application Development (RAD) methodology, code generation is done to create the actual system. Automation tools, an integral part of the Rapid Application Development (RAD) methodology are set up to transform data and processes into prototypes (always open to testing), in this stage of the Rapid Web Application Development.
Testing and Turnover: This stage in RAD Software Development makes the Rapid Web Application Development an exceptionally effective process. Prototypes of separate components are developed and tested simultaneously. The earlier phases of the RAD software ensure seamless flow of data and interfaces between the disparate components (if they do not appear to be so, this stage remedies the issue). Testing each element, especially with regard to user feedback is instrumental in preventing major glitches in future.
Every phase of the Rapid Application Development Platform works in tandem with feedback from users who are actually interacting with prototypes of various elements of the application. Constant feedback and consequent improvement in the RAD software development model facilitates smart troubleshooting and debugging features.
Rapid Application Development Platform vs the Traditional Systems Development Life Cycle (SDLC)
When software development follows a traditional SDLC, the majority of planning, resource gathering, and analysis is done prior to the start of the actual coding process. So, the fundamental parameters for application generation are determined on the basis of vague ideas and objectives. Customer requirements are collected from individuals and potentials users on the basis of a design document. Users have no access to a working build for a long time.
User feedback is also often collected once software design is completed. By then, any changes to the code to accommodate feedback would entail major alterations to the software. Similarly, deferred testing means that troubleshooting would mostly involve changing source code and reconfigure the basics of the software. This is time-consuming and by the time a product hits the market, it turns out to be outdated, or not competitive enough.
In contrast, the RAD software emphasizes on iterative and incremental working models. The RAD phases operate on the basis of testing, customer feedback, and requirements. Changes can obviously be more easily accomplished in the midst of the process rather than at the very end. The Rapid Application Development Platform not only surpasses in terms of speed of delivery but also guarantees a flawless product.
Conditions for Implementing the Rapid Application Development Platform
Using the RAD software can prove to be a major upliftment of the software development process. However, certain conditions must be met for the RAD software to be applicable.
- It should be possible to divide the project into multiple parts, with corresponding personnel working on each functional module.
- ·The company and/or client must be able to devote substantial funding to hire multiple teams of dedicated designers, coders, and testers. Each of the RAD software phases requires numerous teams. The RAD software necessitates a complete focus on each individual involved.
- ·The budget must also be able to accommodate the purchase of automated code generation tools.
·Clients, users, and designers must operate in a system in which there is a constant and seamless exchange of information. They must have enough time and energy to devote to multiple re-coding activities, using multiple versions of the application.
- ·Project completion is expected in two to three months.
·Every individual working on the project must possess a flexible mindset. Since around the clock availability and multiple changes are fundamental to the RAD software, one might have to adjust schedules and commitments accordingly. Both customer and developer must be fully committed to the schedule put in place.
Before gauging the model of software development to be used, the company must always consult with a domain expert with relevant business knowledge who can determine the method that best satisfies its objectives. While the Rapid Application Development Platform is extremely effective, it is possible that certain businesses and products might require more traditional systems development life cycle.
Undoubtedly, the Rapid Application Development Platform is high in efficiency and provides just as high returns. Due to the factors that determine its success, the implementation of a RAD software, however, should only be considered after a careful assessment of the company’s financial, technical and administrative capabilities. Doing so without adequate expert opinions and consultation could doom both the Rapid Application Development Platform and the intended software to fail. If properly utilized, the RAD software stands second to none as a resource for excellence.
