Introduction to Rational Application Developer



Rational Application Developer (RAD) is an integrated development environment from IBM, built on the Eclipse platform. It provides developers with a powerful suite of tools to streamline the entire application lifecycle, from coding and testing to deployment and maintenance. Originally launched as a successor to WebSphere Studio Application Developer, RAD has evolved significantly over the years, integrating advanced features for developing Java EE applications, web services, and enterprise applications.

Developers often use RAD to create complex, multi-tier applications that require integration with various backend systems, databases, and cloud services. Its user-friendly interface, combined with extensive tools and frameworks, makes it a popular choice in enterprise settings where reliability, scalability, and performance are paramount.
