types which have no internal Component.there are two types
of Composite datatype:
1.Records: they are used to store dissimpilar data as a
logical unit.E.g if employee is a record then emp
id,salary,department can be its various components which
together form the record.Records can be user defined
records or delared using %rowtype based of row of table or
