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...
Modelling data secrecy and integrity
The paper describes a semantic data model used as a design environment for multilevel secure database applications. The proposed...
Graphical query formulation for an entity-relationship model
A query language is defined in which users graphically manipulate entity-relationship (ER) diagrams to formulate queries. The theoretical foundation...
Steps towards a method for the formal modeling of dynamic objects
Fragments of a method to formally specify object-oriented models of a universe of discourse are presented. The task of...
Methodologies, tools and languages for building ontologies. Where is their meeting point?
In this paper we review and compare the main methodologies, tools and languages for building ontologies that have been...
Modeling relationships in object-relational databases
We propose an approach for designing an object-relational database. We inspect each case of semantic relationships (one-to-one, one-to-many, many-to-many...
An EREC framework for e-contract modeling, enactment and monitoring
A contract is an agreement between two or more parties to create mutual business relations or legal obligations. It...
