The object-oriented approach has evolved as a software design and programming method. It was later adapted to systems analysis as a modeling method. Modeling in systems analysis is used to create a representation of the organizational domain for which the information system is developed. Such a model is termed an enterprise model. A modeling method comprises a modeling technique and a modeling ...

Object-oriented frameworks and design patterns are useful abstractions that are relatively new to the object-oriented paradigm. The implementation of the abstractions, however, suffers from a number or problems due to the fact that insufficient language support is provided by the traditional object-oriented paradigm. In this paper, we analyse these problems, study the different approaches for p...

Although object-oriented methods make extensive use of relations between objects, these relations, other than inheritance and part-of, can not directly be represented by the conventional object-oriented model. This means that relations which are identi ed during analysis and design have to be implemented on top of the object model, i.e. by using method code and message passing, rather than by e...
