A New Integrated System of Logic Programming and Relational Database

Based on the study of the current two methods-interpretation and compilation-for the integration of logic programming and relational database,a new precompilation-based interpretive approach is proposed.It inherits the advantages of both methods,but overcomes the drawbacks of theirs.A new integrated system based on this approach is presented,which has been implemented on Micro VAX Ⅱ and applied to practise as the kernel of the GKBMS knowledge base management system.Also discussed are the key implementation techniques,including the coupling of logic and relational database systems,the compound of logic and relational database languages,the partial evaluation and static optimization of user‘s programs,fact scheduling and version management in problem-solving.

A new integrated system of logic programming and relational database

Based on the study of the current two methods — interpretation and compilation — for the integration of logic programming and relational database, a new precompilation-based interpretive approach is proposed. It inherits the advantages of both methods, but overcomes the drawbacks of theirs. A new integrated system based on this approach is presented, which has been implemented on Micro VAX II and applied to practise as the kernel of the GKBMS knowledge base management system. Also discussed are the key implementation techniques, including the coupling of logic and relational database systems, the compound of logic and relational database languages, the partial evaluation and static optimization of user's programs, fact scheduling and version management in problem-solving.
