What is degree and cardinality in er diagram?
Can you give me an example of degree and cardinality in an ER diagram?
Of course! Let's say we have two entities, Students and Classes, and they have a relationship of Enrolls In. If a student can enroll in multiple classes, and a class can have multiple students, we would say that the degree of the relationship is "2" and the cardinality is "many-to-many."
