Hi Ashish,
There are several, but they are generally about implementing a more user
friendly database from a well normalised structure.
You can use views to do any or all of:
act as a filter on fields or records which can be accessed by given users,
act as a stored query to avoid writing a commonly used SQL,
 aggregate normalised tables into a single virtual table, so that access
 does not require as complex a join, thus it can hide the complexity of the
 database structure from applications or users.
An example use is to have a view which provides only the current version
of data from a database which stores multiple versions of the data.
Cheers,
Brent Wood
