A CDE Definition
A comprehensive Ada development environment for Unix systems from IBM. The tools extend to Ada 95/Ada 83 development as well as support for C/C++. Rational Apex evolved from the original, proprietary hardware-based Ada environment that Rational Machines was founded on in the early 1980s. Later renamed Rational Software, IBM acquired the company in 2003. See Rational Rose.
An object-oriented analysis and design tool that runs on Windows and Unix platforms from IBM. It supports the Unified Modeling Language (UML) as well as the earlier Booch and OMT notations. With contributions from many large companies, Rational Software was the driving force to unify Booch, OMT, OOSE and others into UML.
The base product is used for modeling applications, but versions of Rose are available that generate C++, Smalltalk, Ada and SQLWindows. The product was originally from Rational Software, which was acquired by IBM in 2003. See Rational Apex.
