Abstract

In Model Driven Architecture (MDA), business requirements for the information system are described in a Computation Independent Model (CIM), which additionally can describe knowledge of the business, and structure and behavior of both business and supporting information system. In object-oriented software development requirements are described by use cases. Use cases and identification of them are informal and application-oriented. Goal-based approaches provide a more systematic way for discovering use cases from informal knowledge about a system. The main and very important difference of the approach suggested in this chapter is that we ground our domain analysis on a mathematical engineering model, Topological Functioning Model. It is a formal holistic computation independent business model, whose characteristics help in avoiding challenges in functional requirements caused by non-systematic approaches and fragmental nature of use cases, namely, completeness, traceability and compliance with the problem domain.
