The database is intended for applications, such as engineering data management, which have complex data structuring requirements and special data accessing needs.

Towards an Object-Oriented Data Model for a Mechanical CAD Database Systemnalysis for the data model of this system. To aid in identifying these requirements, an object-oriented solid modeling system was developed. We give a brief overview of this system, discuss requirements for the data model, and present the first version of this data model.
