Glueing CASE Tools Together in a Heterogeneous CASE Environment

The integration of different existing tools, each of them not covering the whole life cycle, to a SEE (Software Engineering Environment) is an actual task. There are two main mechanisms of integration. The fIrst one is the vertical integration, that means, that a common user interface and a common data base are available for the tools to be assembled into a CASE Environment. ( The second one is the horizontal integration concerning the interface between tools for exchanging information. Here the semantics of the information is the mainly important part. Either the interface can be an exclusive mutual link between two tools, which is an optimized but specific solution, or different tools can be connected by a Common Data Model for Integration, which is a general but very complex solution.
