Abstract
An architecture is given for engineering data management that incorporates current work on engineering product standards as well as current work in database research. In particular, a framework that views an engineering design environment as an integrated, heterogeneous database system is presented. This integrated view of data makes use of data exchange standards in PDES/STEP, presenting a framework for the representation of meta data that describes an object-oriented view of data and supports an object-oriented query language for the retrieval of data from multiple data sources. How the use of active database technology supports a rule-based approach to constraint propagation and change notification is also described. >
