What is an entity relationship diagram?
An entity relationship diagram (ERD) is a graphical representation of the logical structure of a database. It is used in database design to illustrate the organization of data and the relationships between different entities (which are usually objects or concepts about which information is collected).
In an ERD, entities are represented as rectangles, while relationships are shown as lines connecting entities. Attributes, which are specific characteristics or properties of an entity, are represented as ovals connected to its corresponding entity.
These types of diagrams are essential in the data modeling process, as they allow designers to visualize the structure of the database before implementation, making it easier to identify and correct potential problems.
