Chen (Peter Chen)

Peter Chen is a renowned computer scientist who introduced the Entity-Relationship model in 1976, a fundamental framework for designing and visualizing databases. This model helps organize data by representing real-world entities (like people or products) and the relationships between them (such as a person owning a car). It provides a clear, structured way to plan and create databases, making data management more efficient and understandable. Chen's work has significantly influenced database design and remains a foundational concept in information systems today.
