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...
The operational semantics of user-defined relationships in object oriented database systems
In semantic data models, abstract relationship (e.g. generalization, aggregation, etc.) semantics are defined, specifying how insertion, deletion and modification...
A conceptual design aid environment for expert-database systems
With the actual penetration of expert systems into the business world, the question is, how the expert system idea...
A framework for object migration in object-oriented databases
This article presents a framework developed for accommodating various object migrations in 'statically-typed' object databases. Requirements for supporting object...
