Expert Database System for Converting Unfit Query to Standard SQL Query

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: 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 and that an unfit query, for a simple reason, would be rejected. This rejection affects communication momentum and causes user disappointment by not having the desired data. The proposed system aims to prevent rejection of unfit queries entered by the user by preparing them for optimization so that they are in a simple, correct form which is accepted by the DBMS.
