Database Management System (ERD)

An entity-relationship diagram for a database management system (DBMS).

The ER diagram presents a model of a fictitious data management system (DBMS). It depicts the entities needed for the metamodel of databases, their tables with columns, keys, and relationships. Our example DBMS also supports multi-user access and various permissions for particular database objects. The model shows the relationships between the modeled entities.
