The ER or Entity Relational Model is a high-level conceptual data model diagram. ER diagrams are used to model and design relational databases in terms of logic and business rules in a logical data model and in terms of the specific technology to be implemented in a physical data model In software engineering an ER diagram is often an initial step in determining requirements for an information systems project. Workers lack fundamental knowledge in these fields.
