Towards the Refinement of Topological Class Diagram as a Platform Independent Model

In this paper a refinement process of topological class diagram is presented. The refinement process is aimed to lower the abstraction level of the initial topological diagram which is obtained from the topological functioning model. Topological functioning model uses mathematical foundations that holistically represent complete functionality of the problem and application domains. By lowering abstraction level of the topological class diagram, it gets additional information which is needed during the software development and maintenance phases. The refinement process consists of six steps. As a result of applying refinement process, a rich topological class diagram with lower abstraction level is obtained. The refinement process is a part of topological modeling approach and it is shown in the context of laundry business system software development project. By applying topological modeling approach it is possible to enable computation independent model creation in a formal way and to enable transformation from it to the platform independent model
