This Student SQL ER Diagram is used to visualize data and relationships between system entities. An ER Diagram, at its core, explains the logical structure and information flow within a data model. An entity-relationship diagram emphasizes entities, attributes, and relationships using predefined symbols to visualize the architecture effectively. Preparing an ERD is an important first step in designing a database, as it aids in data flow analysis and due diligence of related system requirements. Database data models are designed using an ER diagram. When creating a new data model, creating an ER Diagram aids in the capture and documentation of system requirements.
