Organization of This Book
Access Database Design & Programming consists of 17 chapters that are divided into six parts. In addition, there are five appendixes.
Chapter 1 examines the problems involved in using a flat database—a single table that holds all of an application’s data—and makes a case for using instead a relational database design consisting of multiple tables. But because relational database applications divide data into multiple tables, it is necessary to be able to reconstitute that data in ways that are useful—that is, to piece data back together from their multiple tables. Hence, the need for query languages and programming, which are in many ways an integral part of designing a database.

The first part of the book then focuses on designing a database—that is, on the process of decomposing data into multiple tables.
Chapter 2 introduces some of the basic concepts of relational database management, like entities, entity classes, keys, superkeys, and one-to-many and many-to-many relationships.
