Using Rational Rose RealTime(R) and CORBA to Facilitate Distributed Software Architectures and Designs

A prototyping effort was started in September of 1999 to evaluate the UML modeling tool Rational Rose RealTime(R) (RoseRT) and its Connexis and add-on package for the distribution of a model. This evaluation was undertaken to determine the potential of such tools to improve development productivity and specifically the fitness of RoseRT and CORBA based distribution mechanisms such as Connexis for ONG products and their development. A series of prototype models were created to test aspects of each tool component. Our effort provided several important observations: We found use cases and scenarios are powerful requirements capturing tools. The Connexis add-on to distribute a RoseRT model has good added value. Well-integrated tools are a great productivity enhancement. The use of good design techniques and appropriate patterns are still required.
