Crow's Foot Notation
Crow's Foot notation is a visual way to represent relationships in a database. It uses symbols to indicate how different tables (like lists of data) relate to one another. A "crow's foot" symbolizes "many," showing that one entry in a table can connect to multiple entries in another. For example, a single customer can place many orders. This notation helps to organize and clarify data relationships, making it easier for developers and analysts to design and understand complex databases. It’s a key tool in database design that simplifies the structure of information.
