8.1. Overview of the Use Cases

The three use cases presented in this book are as follows:

• The first case is focused on improving data display. It takes a large amount of data and displays it in an interactive grid that shows how AJAX can remove a common cause of "click and wait."

• The second case looks at using AJAX to build login systems. Updating the standard process allows for quicker feedback and makes it easier to add logins to applications like the comment systems on blogs.

• The final case is a Web-based trouble ticketing system used to provide technical support. This case focuses on building a complete AJAX application. It shows various techniques that can be used to manage an application that is written primarily in JavaScript. It also shows what a lightweight server back end would look like.
