“Ever wish you could draw a few diagrams, press a button, and have a working software system that meets your needs? Sound like magic? Perhaps, but that’s a major part of the Executable UML vision. The basic idea is that you will use a CASE tool to develop detailed UML diagrams and then supplement them by specifications written in a formal language, presumably the OMG’s Object Constraint Language (OCL). The basic idea behind Executable UML is that systems can be modeled at a higher level of abstraction than source code, simulated to support validation of your efforts, and then translated into efficient code. This higher-level of abstraction should help to avoid premature design, enable you to change your system as your requirements evolve, and to delay implementation decisions until the last minute.”
