RELATIONAL DATABASE SEARCH PROCESSING METHOD USING SET, PHASE AND SYMBOLIC LOGIC

摘要

PROBLEM TO BE SOLVED: To solve problems that much labor and computer resources are required for the management, maintenance and storage of class objects in order to secure reference consistency restriction and application purpose restriction and management information stored in a relational database should be dually managed in conventional methods.;SOLUTION: Reference consistency restriction necessary for the connection of table groups to be referred to by an SQL format is automatically secured by analyzing the structure of the relational database and the SQL format securing application purpose restriction is automatically prepared by interpreting the phase characteristic of an application purpose only by information stored in a data dictionary on the basis of the logic of sets and phases and constituting SQL syntax corresponding to the application purpose. Consequently human resources, hardware resources and software resources required for respective processes can be sharply reduced.;COPYRIGHT: (C)2005,JPO&NCIPI
