Abstract
Engineering design process requires more dynamic and more powerful data base than usual one. Data management must be flexible enough and data structure should be free from the first normal form restriction of the relational data model.
Examining design process we remark that data base is rather a target to be constructed by coordinated works of designers than a static catalog to be referred to. That is why Engineering Data Base is required to fit well to dynamic changes.
Design is related directly or indirectly to shape or form of things to be designed. Engineering Data Base, therefore, must support geometric models used in design process. A canonical geometric model is proposed, which can be represented by making use of an extended relational model, and can be used for engineering design in wide range of industries. Manipulation of data related to such a model is studied.
An example of data base system which meets design work requirements is reported.
