Murach's Visual Basic 2008
An introduction to database programming

Database processing is an integral part of Visual Basic business applications, yet most Visual Basic books give you only a chapter or two on handling databases. In contrast, chapter 13 in this book is the first in a 4-chapter section on database programming. It starts out by introducing you to database design and SQL queries. Then, it gives you the conceptual background that you need for learning how to develop database applications in the chapters that follow.
