A lot has been covered in this first chapter. By now we're sure you can see some of the possibilities ColdFusion offers. It's very simple to pull data from a database and believe it or not, it's not much harder to add or change data in the database as well. We've only introduced you to some of the basics of SQL and more will be covered in the book as we move along. There is a tremendous amount of flexibility that SQL offers that is good to know when you continue to learn more about web and database development. There are plenty of good SQL books on the market, and if you plan on working with databases you should pick up a copy to learn more.
