An integrated tool box for the electrical engineer

Abstract

The authors present concepts for the integration of software components such as CAD systems, document management systems and expert systems into a tool box for the electrical engineer and describe the architecture of such a system for computer-integrated engineering (CIE). The kernel of the tool box is an engineering database system based on an active DBMS for maintaining the logical integrity of engineering data. The schema of the engineering database consists of a predefined kernel schema of commonly used objects of electrical engineering and a user-definable part. A CIE modeling system is made available for the definition of user-specific data structures, relationships, and engineering rules.<>
