About this document
Understanding the Entity-Relationship Model by avishana is a document available to read on EtoBox.
The document discusses the entity-relationship (ER) model for database design. It explains that the ER model has three phases: conceptual, logical, and physical design. The conceptual design phase uses the ER model to represent entities, attributes, and relationships. Basic constructs in the ER model include entities, attributes, relationships, entity types, and relationship types. ER diagrams provide a graphical notation for representing schemas in the ER model.
