Abstract
Aiming at a uniform relational treatment of data items which are related to various aspects in manufacturing, this research emphasizes convenient facilities for defining relational data schemes, manipulating relational data, and incorporating with application uses. To facilitate the definition of data scheme, the generic relational model is utilized to more faithfully catch different levels of data abstraction. The design of the generic relational model is eased by a syntactic approach. Also, to support such a database, a query language based on SEQUEL has been modified and is now being implemented. By a systematic database design methodology and a powerful query language, data ranging from geometric description to machinability can be represented as flat relational tables rather than files or trees with pointers.
