5.6. Summary

Although the technique is somewhat old-fashioned, it demonstrates, to a degree, how processing flows in an Ajax application. In addition, the "dark art" of communicating information between frames was covered. However, two items of note from this chapter will be carried into later chapters: JavaScript and MySQL stored procedures.

Regardless of any opinion to the contrary, JavaScript has become essential in the development of web applications that feel more like GUI applications. And even though some shortcuts may have been taken with these examples, they do serve their purpose.

The inclusion of stored procedures in MySQL was a purely personal decision on my part. Originally, I considered using straight SQL; however, it has been several years since I created any kind of nontrivial application using anything but stored procedures. In addition, because the topic of stored procedures in MySQL is so new, trying to find examples is pretty much like looking for a unicorn. So I thought, why not include a few examples here? And as you've probably determined by now, I like examples.
