Rational Rhapsody, a modeling environment based on UML, is a visual development environment for systems engineers and software developers creating real-time or embedded systems and software. Rational Rhapsody uses graphical models to generate software applications in various languages including C, C++, Ada, Java and C#.
Rational Rhapsody helps diverse teams collaborate to understand and elaborate requirements, abstract complexity visually using industry standard languages (UML, SysML, AUTOSAR, DoDAF, MODAF, UPDM), validate functionality early in development, and automate delivery of high structured products. 
Rhapsody was first released in 1996 by Israeli software company I-Logix Inc. Rhapsody was developed as an object-oriented tool for modeling and executing Statecharts, based on work done by David Harel at the Weizmann Institute of Science, who was the first to develop the concept of Statecharts.
In 2006, I-Logix's shareholders sold the company to Swedish software company Telelogic AB. Rhapsody became a Rational Software product after the acquisition of Telelogic AB in 2008, like all former Telelogic products. Since the rebranding, Rational Rhapsody has been integrated with the IBM Rational Systems and Software Engineering Solution.
