We learned a lot in this chapter about using a database to store persistent data.

Specifically, we covered:

We also discussed how to make a web application respond to mouse clicks and request new data from the server without using<form> elements but using jQuery's click() and live() methods.

Now that we've made the first step in using a database, we're ready to create more elaborate databases designs, consisting of more than a single table, and look at the methods to define relations between these tables which is the topic of the next chapter.
