Operations,troduced so far lack formal semantics. The languages based on data structures are similar to network languages and based on a calculus. use a formal definition for semantics of ER types. Different ER languages such as DESPATH, ERROL, ER-LANG (IBM), GDL, GOR-DAS, GQL/ER, LSL, NETUL, SQL/ER have been proposed.

Applying the Theory,algebra approach . For this model a simple design methodology is available. Furthermore, the HERM approach can be downloaded to an intelligent user interface for a variety of database systems and can be used in federated database systems. Based on these achievements, a sound and powerful design methodology can be developed.
