The overall mantra of this book is: Don't reimplement database features in your application that the dbms can do for you. I really strongly agree with this, and even if you don't recall any of the concrete recipes in this book then this mantra will hopefully stick.

Don't make it a hard rule, though. There are exceptions to everything. Sometimes it's easier, faster or more flexible in the client.
