Why Is This Chapter Here?
You might wonder why we’re discussing database design topics in this book and why they’re included in a beginning chapter. The reason is simple: If you have a poorly designed database structure, many of the SQL statements you’ll learn to build in the remainder of the book will be, at best, difficult to implement or, at worst, relatively useless. However, if you have a well-designed database structure, the skills you learn in this book will serve you well.
This chapter will not teach you the intricacies of database design, but it will help you get your database in relatively good shape. We highly recommend that you read through this chapter so that you can make certain your table structures are sound.
