You learned how to create MySQL stored
procedures, how to access them from the business tier of your application, and how to display
the database data using presentation objects and Smarty templates.
In Chapters 7 and 8, we developed the code for an online customer to search for products
in the tshirtshop database catalog, and we implemented many important search engine optimization
improvements. These features are essential for the success of a commercial web site.
In Chapter 9 we discussed how to charge our customers using PayPal. Needless to say,
processing payments is necessary for an online store, and starting with a service that does
most of the work for you is the simplest way to start charging your customers.
CHAPTER 22 ?– USING AMAZON.COM WEB SERVICES 687
In Chapters 10 and 11 we created the TShirtShop administration functions that allow you
to easily edit your catalog??™s departments and categories, product descriptions and prices, add
or remove items from the TShirtShop catalog, and perform many other administrative tasks.
Chapters 12??“15 represented the second stage of development, where you replaced PayPal??™s
shopping cart with your own shopping cart solution. Additionally, you added AJAX and dynamic
recommendations features, making your site friendlier to your visitors. At the end of this stage
of development, your site was once again fully functional and ready to accept your customer??™s
orders.
