An entity-relationship diagram (ERD) is a graphical representation of the relationships between different entities in a database or library management system. An ERD helps to visualize how the data objects in a database or library management system are related to each other. It shows the relationship between entities, such as tables or objects, and their attributes, as well as specifying keys and constraints. By creating an ERD, it is easier to understand how all of the elements fit together in the bigger picture. With the help of EdrawMax, you can easily recreate a similar diagram.
