Abstract
Lack of support for Entity-Relationship (ER) semantics in object-oriented programming languages (OOPL) remains a key roadblock to the effective object-oriented systems development. We extend the object-oriented programming language Smalltalk with Entity-Relationship semantics including entity integrity constraints, cardinality constraints, and set-oriented data access. The meta-classes: PermanentObject, EntityObject, Relationship, and JoinClass provide the necessary structures and operations to support Entity-Relationship semantics. These meta-classes greatly reduce efforts to implement an Entity-Relationship model into an object system.
