Summary:Abstract: "PHI is an experimental distributed deductive database system developed in the Fifth Generation Computer Systems Project in Japan. It is implemented on Personal Sequential Inference Machines (PSI) also developed in the project. The design of PHI started in 1985 and it has been operational since 1988. A deductive database consists of intensional and extensional databases. PHI is composed of two layers which handle intensional and extensional databases respectively. Query language of PHI is Datalog and its query processing is performed in a bottom-up manner. Query optimization of PHI is the combination of query transformation and techniques developed for relational databases
This paper discusses the design, implementation and evaluation of the deductive database part of PHI.
