A 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...
متن کاملDDB Trees: A Basis for Deductive Database Explanations
The power of deductive systems in general is that programs express what should be done and not how it should be done Nevertheless deductive systems need debugging and explanation facilities Indeed their operational semantics is less abstract than the declarative semantics of the programs If users have to understand all the low level details of the operational semantics much of the bene ts of us...
متن کاملMeta-Level Control for Deductive Database Systems
Will reading habit influence your life? Many say yes. Reading meta level control for deductive database systems is a good habit; you can develop this habit to be such interesting way. Yeah, reading habit will not only make you have any favourite activity. It will be one of guidance of your life. When reading has become a habit, you will not make it as disturbing activities or as boring activity...
متن کاملDeductive 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 Framework for Deductive Database Design im Decision Support Systems
A three-level framework for design and implementation of deductive database management systems is described. The three levels consist of the abstraction, for abstracting the real world semantics, the language, for man-machine communication, and the environment, for specifying the hardware/software environment. This framework is applied to some representative systems. Based on the results, an ar...
