Query: Book defines relationship marketing

My teacher in grad school used this book in our database marketing class and Mr. Vavra hits the nail on the head. If you own a business or work in a company chances are that reading this book will open your eyes - and the deficient marketing practices and priorities that you see will blow you away. This book is written without the stodgy business speak.Enjoy
