It seems that ,Information Modeling is a challenging section and difficult to get more marks on. I am prepraring for my exam and right now ,I have begun by reading professional XML 2nd edition by wrox. Can anybody guide me as which are the important chapters from this book ,i should really focus on . Besides Which are the other sources of information on Information Modeling which will prepare me best on this section from exam point of view? I also have XML bible and "Java and XML" by oreilly for reference. Thanks in advance, Dip
