If one needs introductory Haskell programming tutorial explaining about 
the language concepts from first principles, then one should read a 
textbook written for that purpose such as "Programming in Haskell".

"Real World Haskell" is a collection of practical tips and know-hows to 
get things done at work rather than a step-by-step Haskell tutorial. And 
I believe that many other O'Reilly books are like that.

What do you mean by that "they are trying database programming is 
possible in Haskell"?  I've done very simple database programming in 
Haskell using HDBC, and it just works using the binary package from 
debian. If you need more complicated examples, you can take a look at 
the hpodder source code or any other applications that use database. 
They are all on Hackage.
