Semantic Object Language

While UML is the accepted visual language for object-oriented system modeling, it lacks a common semantic foundation with a standard visual syntax. Furthermore, it does not cleanly mesh with external visual modeling languages such as entity relationship diagrams and relational data models. By restating UML and ER in terms of a common underlying semantic and syntactic modeling platform, a comprehensive, encapsulated, and truly unified software modeling technique becomes feasible. Expressing System Design: UML and ER Object-oriented programming has become the dominant paradigm in software engineering and system design. Contemporary software designers employ the Unified Modeling Language (UML) to describe software systems. It is a graphical notation used to express requirements analysis and software design (Fowler, 2000). Briefly, UML consists of nine core types of diagrams: • Activity Diagram. This shows behavior with control structure. It can show many objects over many uses, many objects in a single use case, or implementation o
