Understanding Entity-Relationship Models by Nipun Somani is a document available to read on EtoBox.
The Entity–Relationship (ER) model provides a structured framework for designing databases through diagrams known as Entity Relationship Diagrams (ER Diagrams). Key components include entity sets, represented by rectangles, and relationship sets, represented by diamonds, along with various attributes depicted through different shapes. Weak entities, which depend on other entities for identification, are illustrated with double rectangles in the diagram.
