Chapter 23. Web Pages that Manipulate Database Records
Just displaying database information on a Web page is useful, but you may be more
interested in using the Web to collect information from your site's visitors. Maybe
something as simple as an online registration form will do the trick. Other times,
you may have something more ambitious in mind梐 full-fledged ecommerce system,
for example, which doesn't pay the bills unless it provides a way to collect product
orders and credit card numbers.
Once you've got data in the database, clearly you'll need a way to update and delete
that information. After all, prices change, products are discontinued, and you may
suddenly want to remove any record of "Harvey the Wise Guy" from your site's online
guestbook. Thankfully, Dreamweaver makes changing information in a database
simple and painless.
You may feel more comfortable learning these concepts by doing them. If so, turn to the tutorial in
Section 23.5 before reading this next section.
