Difference between compound key and composite key ? Please any one help on this
https://en.m.wikipedia.org/wiki/Compound_key "In database design, a composite key is a candidate key that consists of two or more attributes (table columns) that uniquely identify an entity occurrence (table row). A compound key is a composite key for which each attribute that makes up the key is a simple (foreign) key in its own right."
thanks for your response but need more clarity
