Crow's Foot Symbol

Crow’s Foot notation is a visual way to represent relationships between data in diagrams called Entity-Relationship Diagrams. The "crow’s foot" symbols indicate how many instances of one entity are associated with instances of another. For example, a single line with a crow's foot at one end might show a "one-to-many" relationship, meaning one record in one table can relate to many in another. This notation helps database designers clearly depict how different data entities connect, making it easier to structure and understand complex information systems effectively.
