ABSTRACT

The Entity-Category-Relationship (ECR) model extends the Entity-Relationship (ER) model with the concepts of subclass and generalisation categories. In this paper semantics of update operations for the ECR model are discussed. The proposed update operations can be implemented as an interactive data manipulation language. This language is based on algebraic operators that can be invoked graphically to operate on ECR diagrams. A method of implementing the graphical ECR interface for accessing relational database systems is proposed.
