I wouldn't even consider recommending any book by Fabian Pascal for a beginner, the concepts and presentation will at best confuse them and more likely his writing style will put a beginner off so badly that they just abandon the idea of data modeling altogether.
If I knew a bit more about what Hamzaali wanted in terms of data modeling (background, goals, etc) I could probably suggest a good book, but without more information I'm a bit handicapped.
