ABSTRACT
This chapter explains how to implement system administration functions such as including new users and devices in the system, deleting them, etc., using popular Web 2.0 tools. The World Wide Web, or Web, is a system of interlinked documents distributed throughout the Internet to share information in an automated manner. The Web has become one of the most successful applications in the Internet, and it has evolved from static hyperlinked documents to interactive applications, providing e-commerce, mapping, multimedia, and social networking services, among others. A Google Web Toolkit-based application consists of client-side code and the server-side code. In order to implement the “create device” function, a database needs to be designed and implemented. In order to create or add a new device in the system, it is imperative to create a window to request the new information from the system administrator and submit it.
