hi,

View are improves perfromance in the following aspects

1. If you want to use more than two table in 'JOIN' condition better to use Views . It will improves performance of a program

2. If you want to use mutiple FOR ALL ENTRIES clause, better to club all SELECT statement in a view.

note:

1.Views does not contain data in it. It fetches data from the database only depending on the condition ...

2.Views are part of data dictionary. They are a window to view the data in database

3.views can be used to give security to data. users can be allowed to view only basic data only
