DEDUCTION OBJECT ORIENTED DATA BASE SYSTEM

摘要

PURPOSE:To attain a deduction object oriented data base system by adding an object oriented notion to a deduction data base system that can present only a deducing function. CONSTITUTION:A deduction data base executing means 112 provides a base unit section obtained based on the 1-story predicate logic to an object oriented language executing means 111 from a deduction data base 113. The means 111 provides an object. The correspondence is secured between the base unit section offered from the means 112 and the object provided from the means 111 based on a class-section table 201. The subjects of the questions given from the application programs 121-122 and the answers of a data base system 101 given to those questions are defined as the objects provided from the means 111.
