Chen's 1976 Paper on ER Model

In his 1976 paper, Peter Chen introduced the Entity-Relationship (ER) model, a way to visually represent data relationships in database design. It uses diagrams to show entities (like people or products) and their attributes (like name or price), along with the relationships between them (such as "owns" or "buys"). The ER model helps organize and structure data clearly, making it easier for developers to design databases that accurately reflect real-world scenarios. This framework has become foundational in database design and is widely used in creating efficient information systems.
