For me, to find this book was like finding a gold mine. I felt quite frustrated when I discovered that lots of people talk about database marketing but I couldn't get the information how to get started. It seems like people working with database marketing aren't eager to share their knowledge. Or they just can't explain in an understandable way how it works or they don't know how (even if they say they do). This book tells you why, how, when, where to succed in database marketing - truly a bible for the believers. It's easy to understand for everyone without knowledge nor experience in database marketing. But it's also a book for the proffessionals in this field. I bet everyone will get helpful hints from the author and it's well invested money to buy it.
