Software and system engineering is becoming more and more a scope of activity where different tools work together sharing common data. Therefore, a non-standard database system called PRODAT has evolved to fulfil the requirements imposed by the appliations. The main goal of PRODAT is to be application-oriented i.e. it allows for a powerful, yet comfortable representation of design objects, it supports the design process during the whole life-cycle, and of course, the co-operation between several designers or design tools. Therefore, mechanisms are offered to keep the "semantic gap" between the application model and the terms of the data model - e.g. objects and relationships - as small as possible. In this contribution, the data model of PRODAT will be presented. It will be restricted to the notion of simple and structured objects and the version and configuration management facilities. The practical usability of the model is demonstrated by a case study. (IITB)
