Creating web pages was fairly straight-forward—in the early 1990's. Today, there are many, often competing technologies available for creating a web experience. Remarkably, all these differing technologies and strategies interoperate in a relatively seamless way to serve the billions of people who use the World Wide Web and the Internet.

IBM's Lotus Notes and Domino product set—the subject of this book—is a feature-rich, application development technology that has been used to create web-enabled applications since the late 1990's. Since then, it has evolved substantially through several major software versions, and it will continue to advance into the foreseeable future, adapting to the changing web landscape and incorporating new technologies and methods as appropriate.

One of the delightful aspects of Domino is its backwards compatibility. With few or no changes, applications written with previous versions of the software, untouched for a decade or more, will run as expected on the newest Domino server.

It is also important to understand that useful applications can be crafted and deployed on a wide range of platforms with relatively little work. A simple application can be cobbled together and rolled out in less than an hour. It would not be a complex application, of course, but it might suffice for basic data collection or an informational website. After that first version rolls to production, providing immediate benefit to users, features and improvements could be added incrementally with little or no downtime.
