Expert Database System for Converting Unfit Query to Standard SQL Query

Abstract

Today, the integration of Expert System (ES) and Database Management System (DBMS) is an emerging research area that is expected to become one of the most important application development products. The proposed system characterized a new class of computer systems to be called Expert Database System (EDS) which is a combination of two systems. They are the Database system and Expert system. This research considers that the database contains a lot of data, which is used by a large number of users with different computer education levels. It is a fact that the DBMS is always strict in query execution that the unfit query for a simple reason would be rejected, this rejection affects communication momentum and user disappointment by not having the desired data. The proposed system aims to prevent rejection of unfit query that is entered by the user through preparing it for optimization it so that it is in a simple correct form which is accepted by the DBMS.
