Entity Relationship Diagram definition

 Entity Relationship Diagram (ERD)

The relationships between entity sets recorded in a database are depicted in an entity-relationship diagram (ERD). An object, or a data component, is an entity in this context. A collection of similar entities is referred to as an entity set. These entities can have qualities defined via attributes. An ER diagram depicts the logical structure of databases by identifying entities, their attributes, and the interactions between them. ER diagrams are used to sketch out a database's design.
