What is RAD?
RAD is the acronym for Rapid Application Development, a model that helps to speed up the development process of some types of software.
The RAD model of software development makes the production cycle very low, reaching an average of 60 to 90 days for completion.
Before, the development of an application / software took a long time to complete, causing several modifications to be made throughout the process for system updates, for example.
RAD works from the idea of reuse of components for the development of new products, avoiding wasted data and time.
The definition of the term RAD ( Rapid Application Development ) was coined by James Martin, author and consultant of information technologies, in 1991.
The RAD is divided into 5 phases, which, if they are obeyed, make the production process quickly boosted:
- Business Model: analysis and negotiation of the project, raising doubts about the stages of the process.
- Data Modeling: planning of all the structuring of the data of the application / software to be developed.
- Process Modeling: structuring the rules of modification, change, exclusion, and changes that may occur in the different objects of the application and how they will affect the other components throughout development.
- Generation of the Application: start of the development process, with the maximum use of already existing components.
- Testing and Modification: performing tests and corrections if necessary.
According to the International System of Units, “rad” is the abbreviation for radian, a measure that consists of the ratio of the length of an arc to its radius.
In the English language, rad is used as a slang for radical or cool, referring to something or someone as “legal”, “cool” or “radical”.
