About this document
Understanding ER Model Concepts by jaswanth.r090 is a document available to read on EtoBox.
The document explains the Entity-Relationship (ER) model, a high-level data model used to define data elements and relationships in a system, represented visually through ER diagrams. It describes components of ER diagrams, including entities, attributes (key, composite, multivalued, derived), and relationships (one-to-one, one-to-many, many-to-one, many-to-many). An example of a school database illustrates how entities and their attributes are structured and related.
