The meaning of ‘RAD’ in Development is ‘Rapid Application Development’.
Meaning of ‘RAD’
When it comes to software development, the acronym RAD stands for Rapid Application Development. This methodology is used to quickly develop applications with a focus on productivity and cost reduction.
RAD is an iterative process that utilizes a combination of prototyping, analysis, design and implementation. It provides a fast-paced approach to developing solutions by allowing developers to build upon existing frameworks and technologies rather than starting from scratch. This allows for the rapid delivery of a working application in less time than traditional methods would require.
The RAD process starts with the identification of user requirements and objectives. This includes gathering information from stakeholders as well as gathering data from existing systems or processes. Once this information has been gathered, RAD then moves on to the first phase – prototyping. This involves quickly creating a prototype of the software application that can be tested and validated by stakeholders. After feedback has been received, it is then analyzed and incorporated into the next iteration of the development process.
The second phase focuses on analysis which involves breaking down the system into components and identifying key elements of functionality that must be included in order to meet user requirements. This helps ensure that each component works in tandem with others in order to create an efficient end product.
Once analysis has been completed, RAD moves on to design where high level designs are created using UML or other modeling techniques. These designs provide direction for developers when coding, testing, and deploying their solutions within the application framework provided by RAD.
The fourth phase focuses on implementation where developers use existing frameworks such as Java or .NET along with third party tools like AJAX or JQuery to rapidly build out the application’s core functionality based on high level designs created during design phase. In addition, automated unit tests are also written at this stage in order to ensure that each component works correctly when integrated into the overall solution being developed by RAD.
Finally, once all components have been integrated together into a working whole – testers can validate that everything works correctly before deployment can take place across multiple environments such as web servers or mobile devices depending on user requirements established at beginning of project.
Overall, Rapid Application Development (RAD) is an effective way for organizations to quickly develop applications while reducing costs associated with traditional methods such as Waterfall Development Cycle or Agile Methodologies due its iterative nature which allows developers to build upon existing frameworks and technologies rather than starting from scratch
