An approach to authorization modeling in object-oriented database systems
Authorization is an important functionality that every data management system should provide. An authorization mechanism allows different access rights...
An analysis of multivalued and join dependencies based on the entity-relationship approach
In this paper, we show that multivalued dependencies and join dependencies are not very viable for certain cases of...
Grand tour of concepts for object-orientation from a database point of view
Over the last few years, object-orientation has gained more and more importance within several disciplines of computer science (e.g....
DICE: declarative integrity constraint embedding into the object database standard ODMG-93
In this paper we present a new approach for embedding integrity constraints into object-oriented database systems (OODBS), which can...
A multi-level view model for secure object-oriented databases
In this paper, we employ the view model given by Bertino to design a secure multi-level object-oriented database system....
A system for the semiautomatic generation of E-R models from natural language specifications
Techniques that allow a program to generate E-R models for small application domains are described. The inputs to the...
Towards a formal semantics and inference rules for conceptual data models
A new-from a theoretical point of view-approach to expressing data- or knowledge base semantics is described: the universe of...
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...
