Integration of the Diierent Elements of Object-oriented Software Engineering into a Conceptual Framework: the 3d-model

This report describes a conceptual framework for supporting software engineering. The approach relies on object-oriented concepts, but is not limited to object-oriented software engineering. The basic idea is the notion of a three-dimensional graph structure, which serves to capture and to classify development activities and their resulting documents (the elements of software engineering). The three dimensions views, components, development process of a (software) system serve as fundamental organizing principles, according to which all elements are placed into a uniform, intuitive, but formal meta-structure. From this meta-structure the so-called 3D-model relevant development elements (activities, speci cations) and their relationships with other elements can be derived, together with suitable notations and a process. Hence, the 3D-model o ers a mechanism to de ne an e ective and tailored software development process, which o ers freedom to select its notations, methods, architectures, brie y, all its essential ingredients, to t in the current development situation.
