How the Sample Database Applies to You

If you're not particularly interested in the Historical League or in grade keeping, you may be wondering what any of this has to do with you. The answer is that these example scenarios aren't an end in themselves. They simply provide a vehicle by which to illustrate what you can do with MySQL and tools that are related to it.

With a little imagination, you'll see how example database queries apply to the particular problems you want to solve. Suppose you're working in that dentist's office I mentioned earlier. You won't see many dentistry-related queries in this book, but you will see that many of the queries you find here apply to patient record maintenance, office bookkeeping, and so on. For example, determining which Historical League members need to renew their memberships soon is similar to determining which patients haven't visited the dentist for a while. Both are date-based queries, so once you learn to write the membership-renewal query, you can apply that skill to writing the delinquent-patient query in which you have a more immediate interest.
