Object Oriented System Development Using the Unified Modeling Language (UML)

Regarding object oriented application development, primarily evolutionary procedural models have been discussed in professional publications (see Boehm, Spiral Model 1988; Henderson-Seller s/Edwards, Object Oriented System Life Cycle 1990, P. 152; Meyer, Object Oriented Design 1989). This is based on the theorems of the object oriented paradigm, where objects represent individual “closed system” subsystems. Compliant with the definition of internal and external object structures, it is possible to develop scalable systems. In the evolutionary procedure, every cycle ends with executable software. This is achieved by deriving development results from project goals. These results can be deployed individually as well, so the deployment of each subsystem can be tested at an earlier stage. Additional development includes improvements from real-world tests and implementation of additional subsystems. This makes it possible to present results at an early stage and avoids any “dead ends” in development.
