The following is an entity-relationship diagram showcasing a sports management system. An ER Diagram is an online diagramming tool that makes it easy to create and track disconnects between different entities in a database system. The drag-and-drop functionality and intuitive user interface simplify the process of designing databases, while automated integrity checks keep the model consistent and provide clear visual cues when problems are identified. You can create a similar sports management ER diagram using EdrawMax.
