How to create Queryviews based on main query in BI 7.X

Hi Experts,

1.What is the differance b/n query and query view ?

2.How we can built query views based on one main query?

3.Can we see intial screen popup for query view as main query i.e While we open a query in Query

designer we can see selected chars,k.f ,free chars...for that perticular query which we have

opened.Like that we can see popup for query view also ?

Thanks in advance.
