The pattern isolates business logic from input and presentation. Permitting independent development, testing and maintenance of each.

(DML, DDL and DCL)  Generate query of all possible combination.  Extendibility to apply SQL Grammar file from DBMS vendors.  Use dynamic logical data model information define by user
