Formal deadlock elimination in an object oriented conceptual schema
Object oriented models model structural and behavioural aspects of objects in the Universe of Discourse. As the dynamic aspects...
Object-oriented database schema analysis and inheritance processing: A graph-theoretic approach
In this paper we address the inheritance process in the context of strongly typed Object-oriented database (OODB) systems, allowing...
Dependency preserving refinements and the fundamental problem of database design
We introduce a new point of view into database schemes by applying systematically an old logical technique: translation schemes,...
Default databases: Extending the approach of deductive databases using default logic
Extending the relational data model using classical logic to give deductive databases has some significant benefits. In particular, classical...
A survey of database design transformations based on the Entity-Relationship model
At present, the Entity-Relationship (ER) model is the most important paradigm for conceptual database design. Since the model was...
Evolution of entity–relationship modelling
New modelling languages are continually being developed. Some of them are variants of existing ones, others are completely different,...
Entity-relationship and object-oriented model automatic clustering
Automatic clustering of semantic models allows a multilevel abstraction of the same reality and reduces design complexity. This paper...
Understanding database design expertise
Database design is a complex and time-consuming process. In order to automate database design, an understanding of the nature...
Object-extended OLAP querying
On-line analytical processing (OLAP) systems based on a dimensional view of data have found widespread use in business applications...
Semantic integrity constraints in knowledge-based database design systems
Semantic integrity constraints are used to help ensure that a database accurately reflects the real world in structure and...
