    i search it on net..what i get is

    Partial Key:
    It is a set of attributes that can uniquely identify weak entities and that are related to same owner entity. It is sometime called as Discriminator.

    Hey some questions for your help:

    1) What is a view? Can a view be used to update the base table?
    2) What are the codd's rules?

    3) Why do we do normalisation?
    4) What are the types of Databases?
    5) Which type of Database is Oracle?
