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#.

Developers use Rational Rhapsody to understand and elaborate requirements, create model designs using industry standard languages (UML, SysML, AUTOSAR, DoDAF, MODAF, UPDM), validate functionality early in development, and automate delivery of high structured products.[1]

Rational Rhapsody Design Manager is a web based application that stakeholders, developers, and other team members use to collaborate on the design of products, software, and systems. The product contains a server that hosts model designs which have been developed in Rational Rhapsody. A client extension component included with Rational Rhapsody allows users to connect to a Design Manager server. After connecting to the server, models can be moved into project areas with specific modelling domains based on the industry standard languages supported by Rational Rhapsody. Rhapsody Design Manager also integrates with the Rational solution for Collaborative Lifecycle Management (CLM). In this environment, artifacts can be associated with other lifecycle resources such as requirements, and change requests.[2][3]


Rhapsody was first released in 1996 by Israeli software company I-Logix Inc.[4] 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.[5]

In 2006, I-Logix's shareholders sold the company to Swedish software company Telelogic AB.[6] Rhapsody became a Rational Software product after the acquisition of Telelogic AB in 2008, like all former Telelogic products.[7] Since the rebranding, Rational Rhapsody has been integrated with the IBM Rational Systems and Software Engineering Solution.

Rational Rhapsody Design Manager was first released in June, 2011 by IBM. In December 2011, the product was integrated as a design component in IBM Rational Solution for Collaborative Lifecycle Management (CLM).
