Hi i a a fresher and i want reference materials and manual on focus.
Can u suggest some sites from where i can download some materials or e-books.

Manash,

If you need e-books you can download a lot of books on the Techsupport site of Information builders.
Then click on Publications and then choose "search for Documentation" or use this link directly.

Also on the right hand side of the techsupport site you can find "Techniques/Examples" and also "Best Practice Guides".

Have fun

To supplement Dirk's suggestion, you will require a support agreement so that you can login to the Tech Support site for these manuals. If you do not have a support agreement then you will need to purchase the manuals.
