Rapid Application Development (RAD) software is a type of software development methodology that focuses on rapid prototyping and iterative development. It is a type of agile software development that enables developers to quickly create applications with minimal upfront planning. The goal of RAD is to reduce the time it takes to develop applications and increase the quality of the end product. RAD is often used for developing web applications, mobile applications, and other types of software. It is based on the idea that developers should be able to quickly create prototypes and iterate on them to improve the end product. RAD is an iterative process that involves the development of a prototype, testing it, and then making changes to the prototype based on feedback from users. This allows developers to quickly develop applications and make changes to them as needed. RAD is a great way to quickly develop applications and improve the quality of the end product.
