If you studying for the Family Application Development Exam (703) certification exam, you will find the book to be quite helpful. I wish I had this book when I was studying 703 certification exam.
Many of us concentrate on only one or two of the methods of communicating with DB2 in our programs. The book does a good job of explaining embedded SQL programming, CLI/ODBC programming and Java programming. It is difficult to remember all the information about all of these and the book gives a great review of the programming methods.
The book opens with a detailed roadmap on DB2 certification that explains the various tracks. It also has a good explanation of how to register for tests and how the tests work. Understanding how the tests work can save you valuable time on test day.
Like Roger's other certification books, this one is arranged around the test sections, which seems like a good way to study for the tests. Roger likes to white space, pictures and diagrams to improve the readability of his books and this book follows that pattern. Each chapter closes with a section of practice questions, which have very informative answers that follow.
