I ordered this book because I thought when I get myself a book about nothing else but databases and Delphi/Kylix it would be extensive. However this book doesn't go into the subject deep enough. Almost everything you learn with this book is also mentionned in books like 'Delphi developer's guide' and 'Mastering Delphi'.
Sometimes the author gives a difficult solution to a problem without mentioning the easy way: for example he creates a component for a DBListBox which uses values to store those in a database. This can be done much easier using the OnGetText and OnSetText events of the field however he fails to mention those procedures in the book.
Final remark: there are so many listings in this book that they should have been put on a cd without printing them all out. That would give the customer a better idea about the size of this book.
The Delphi beginners will probably learn something with this book however I would recommend them 'Delphi developer's guide' which covers databases and a lot more!
