Deductive Object-Oriented Database Systems: A Survey
Deductive object-oriented databases (DOODs) seek to combine the complementary beneets of the deductive and the object-oriented paradigms in the context of databases. Research into DOODs has now been taking place for almost ten years, and a signiicant number of designs and implementations have been developed. This paper categorises proposals for DOODs, based on the language design strategy pursu...
متن کاملA Survey of Research on Deductive Database Systems
The area of deductive databases has matured in recent years, and it now seems appropriate to re ect upon what has been achieved and what the future holds. In this paper, we provide an overview of the area and brie y describe a number of projects that have led to implemented systems.
متن کاملDeductive Object-Oriented Database Languages: A Survey
The deductive object-oriented database (DOOD) model is an integration of the object-oriented data modeling paradigm and rule-based deduction to provide a single powerful framework for intelligent database systems of the future. The database language of a DOOD system should speciically be based on a logic to facilitate use of deductive database technology and also to provide the theoretical foun...
متن کاملA Framework for Cooperative Deductive Database Systems
In this paper, we address one important aspect of the problem of designing a cooperative deductive database system, namely, allocation of rules across the deductive database systems. We identify communication cost as the primary consideration in allocation of rules. The problem of optimal allocation of rules has been shown NP-complete, which has prohibitive execution times for large knowledge b...
