Actually, according to Inmon, a data warehouse *is* normalized.

Data marts are not.

The most important thing to understand is that the rules you've worked hard to learn as a DBA are different for data warehousing. You have stuff to
unlearn. Like letting go of "fully normalized". Start by accessing Ralph Kimball's site http://www.ralphkimball.com <http://www.ralphkimball.com> He posts a lot of the basics of Data Warehousing on his site in form of magazine articles he's written over the years. In my opinion, Ralph is better at explaining the "big picture" of DW than anyone else. Once you get
a good grasp of what DW is all about, actually creating a data warehouse mostly involves applying the DBA knowledge you already have. But fail to get
the big picture and you will probably have a disaster on your hands.

Hi All,

Could someone recommend a Data warehouse book for the person who has DBA background?

Also if possible please give me some resource link(docs/URL/etc) to start with.

Thanks in advance
Sami
