Considerable progress has been achieved in the area of virtual database systems, but substantial problems still persist. In this paper we discuss two current research directions: ...
The existing standard for object-oriented databases (ODMG) provides no facility for storing behaviour. This lack of stored behaviour introduces problems for generic applications as...
Database systems are being more and more used, with larger sized databases, and as components of very complex systems, that include numerous protocols. Database security problems ...
This paper surveys a selection of personal research projects which addressed problems related to Software Engineering, and whose solution was inspired by ideas from the field of K...
Functional dependencies (FDs) are an integral part of database theory since they are used in integrity enforcement and in database design. Recently, functional dependencies satis...
