Implementation of a data manager for computer graphics

The Generalization/Aggregation data model is an enhancement of the relational data model. It shows considerable promise for engineering applications because it allows abstract items to be stored in relational databases. However, the G/A model is only a data model. It cannot be used in database applications unless a data language exists to manipulate data items with that model. A database algebra for the G/A model is being developed at Texas Tech. This thesis describes the implementation of a data management system containing this algebra.
