Abstract
The following paper describes a relational deductive database system coupling PROLOG II and VAX RDB (Relational DataBase). The management of storage and research of fact records is delegated to RDB. The utilities of defining indexes in RDB is used to improve the speed with which it retrieves records from the database so as to provide a satisfactory response time. An interface written in PASCAL is called to enable the communication between PROLOG and RDB. Once the interface is established one can query the database with the PROLOG syntax or the occasional user can use an SQL-like DDL (Data Definition Language) and DML (Data Manipulation Language) implemented in PROLOG. No precompilation is required afterwards. PBASE can be used as a general DBMS (DataBase Management System) with a deductive power or it can cooperate with an expert system to manage the voluminous facts stored in the secondary memory.
