Chapter 26. Web Pages that Manipulate Database Records

Displaying database information on a web page is useful, but you may be more interested in the opposite kind of communication—collecting information from your site’s visitors (see Figure 26-1). Maybe you want them to do something as simple as register with your site. Other times, you may have something more ambitious in mind—like accepting and processing product orders using a full-fledged e-commerce system.

Once you have data in a database, you need a way to maintain it—to update and delete information. After all, you’ll change prices, discontinue products, and remove any record of “Harvey the Wise Guy” from your site’s online guestbook at some point. Thankfully, Dreamweaver makes changing this information simple and painless.

You may feel more comfortable learning these concepts by doing them. If so, turn to the tutorial on Deleting Records before you read the next section.

But to record this information, you either need to write your own program or, more simply, use Dreamweaver’s built-in tools to funnel it into a database. Dreamweaver’s Record Insertion Form Wizard and Insert Record server behavior make adding data a simple process.
