Answer Posted / burhan mughal
All candidate keys which are not chosen as "primary key"
are Alternate keys. The key which uniquely identify the
rows of the table and which is made up of more than one
attribute is called Composite key. Generally a candidate
key becomes the primary key of the table. If the table has
more than one candidate key, one of them will become the
primary key, and the rest are called alternate keys.
