The primary class makes every enity bean different. for example, if you have 1 million different bank account entity beans, each bank account needs to have a unique ID that can never be repeated in any other bank account. A primary key is an object that may contain any number of attributes. This could be whatever data necessary to uniquely identify an entity bean data instance.
