After completing this self-contained course on server-based Internet applications software, students who start with only the knowledge of how to write and debug a computer program will have learned how to build web-based applications on the scale of Amazon.com. Unlike the desktop applications that most students have already learned to build, server-based applications have multiple simultaneous users. This fact, coupled with the unreliability of networks, gives rise to the problems of concurrency and transactions, which students learn to manage by using the relational database system.

The growing interest in data mining is motivated by a common problem across disciplines: how does one store, access, model, and ultimately describe and understand very large data sets? Historically, different aspects of data mining have been addressed independently by different disciplines. This is the first truly interdisciplinary text on data mining, blending the contributions of information science, computer science, and statistics.

Information design is the newest of the design disciplines. As a sign of our times, when the crafting of messages and meaning is so central to our lives, information design is not only important—it is essential. Contemporary information designers seek to edify more than to persuade, to exchange more than to foist upon. With ever more powerful technologies of communication, we have learned that the issuer of designed information is as likely as the intended recipient to be changed by it, for better or worse.
