ОтветитьComposite key is generally used in many to many relationships. Thanks for the whole course playlist. It is great!!
Ответитьcomposite keys : used when there is no single key or attribute (i.e no primary keys)available to find unique rows in a table. In that case we use multiple keys to find that unique rows in the table and this approach is called composite keys .
