this i know , i was thinking to get some websites having good content , and
recommended by wht users

your best bet is to find a few tutorials and then try them out and if you hit problems ask on a forum...ideally one that has people who specialise in the SQL db, aspfree.com would be a good place to start if you are using SQL.

A good book or something is pretty important. Its essential that you really understand how a relational database works, and how to make it work without totally messing up the performance side. As a sysadmin i've seen so many bad examples of people doing full table scans on tables with 200.000 rows.. It could be a good idea to take a course on it.

Other than that, fabforce dbdesigner is a great tool for designing databases visually. Download from http://www.fabforce.net/
