What is connectivity use a crow's foot erd to illustrate connectivity?

Connectivity in database design refers to the relationships between entities in an Entity-Relationship Diagram (ERD), often illustrated using a crow's foot notation. In this notation, a crow's foot symbol indicates the "many" side of a relationship, while a single line represents the "one" side. For example, in a relationship between "Customer" and "Order," a crow's foot at the "Order" end indicates that a single customer can place multiple orders, illustrating a one-to-many relationship. This visual representation helps clarify how entities interact and depend on one another within a database schema.
