Describe what a cardinality constraint is
What will be an ideal response?
A cardinality constraint is a rule that specifies the number of instance of an entity that can be associated with each instance on another entity. An example of a cardinality constraint would be a fishing lure company that manufactures lures. Clearly this is a one-to-many relationship since the company manufactures many lures and each lure is manufactured by only one company.
