If for any table, we have more than one primary key, viz If
the table can be uniquely identified by the help of more
than one attribute, the collection is called 'Composite
Key'. If only one key can act as the unique key, it is the
Primary key, rest of the keys are called alternate keys.
Individual keys of the composite key are the candidate keys.
