PHI is an experimental distributed deductive database system. It is implemented on personal sequential inference machines (PSIs). A deductive database consists of intensional and extensional databases. PHI is composed of two layers which handle intensional and extensional databases, respectively. The 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. A discussion is presented of the design, implementation, and evaluation of the deductive database part of PHI.<>
