Evaluation of complex cardinality constraints
In a previous paper, the valence concept, a general method to describe relationships, has been introduced along with a...
Integrating the ER approach in an OO environment
We translate Entity-Relationship (ER) schemas into the object-oriented specification language TROLL light. This language describes the Universe of Discourse...
An extended entity-relationship approach to data management in object-oriented systems
Database programming in object-oriented systems can be supported by combining data modelling and programming technologies such that a data...
On mapping ER and relational models into OO schemas
The Entity-Relationship model (ER model) views data in the form of entities and relationships. The Object-Oriented model (OO model)...
A repository meta model for interactive systems
Developers of interactive systems need a design process that looks ahead to expose conflicting implications of decisions made by...
A commonsense reasoning facility based on the entity-relationship model
Various expert systems have been developed that attempt to automate the database design process. Although these systems may have...
DETERM: Deterministic Event-Tuned Entity-Relationship Modeling
This paper addresses the issue of modeling alternatives in entityrelationship modeling. A method is presented which allows to choose...
A semantic comparison of the modelling capabilities of the ER and NIAM models
Conceptual design (conceptual modelling) is the most important phase in database design as it results in a conceptual schema,...
From entity-relationship models to role-attribute models
This paper is a short presentation of the SOM (Semantic Object Model) approach. SOM was created to fulfill two...
Analysis of binary relationships within ternary relationships in ER modeling
In this paper, we discuss which binary relationship cardinalities are permitted within ternary relationships, during ER modeling. We develop...
