Entity-Relationship (E/R) Model 1
Entity-Relationship (E/R) Model ƒ Widely used conceptual level data model • proposed by Peter P Chen in 1970s ƒ Data model to describe the database system at the requirements collection stage • high level description. • easy to understand for the enterprise managers. • rigorous enough to be used for system building. ƒ Concepts available in the model • entities and attributes of entities. • relationships between entities. • diagrammatic notation. 2
Entities ƒ Entity - a thing (animate or inanimate) of independent physical or conceptual existence and distinguishable. In the University database context, an individual student, faculty member, a class room, a course are entities. ƒ Entity Set or Entity TypeCollection of entities all having the same properties. Student entity set – collection of all student entities. Course entity set – collection of all course entities. 3
