This tutorial series teaches you how to create proof-of-concept applications to access relational and XML data in IBM DB2 9, using Microsoft Visual Studio .NET 2005. Part 1 explains the application specifications, database design, and how to create DB2 relational database objects required in the applications.

Discover three Ajax data transport mechanisms (XMLHttp, script tags, and frames or iframes) and their relative strengths and weaknesses. This tutorial provides code for both the server side and the client side and explains it in detail to provide the techniques you need to put efficient Ajax controls anywhere you need them.

In the creation of a database, a data model and integrity constraints can create certainty in the structure and content of the data. But how do you enforce that kind of control when your data is just text in hand-editable files? Fortunately, validating files and documents can make sure that data fits constraints. In this tutorial, you will learn what validation is and how to check a document against a Document Type Definition (DTD) or XML Schema document.

This tutorial shows you how to use IBM-backed open source and free software to kick-start your Java Web-based application development. You'll learn exactly where to download such components, install them, and get them working for you today.

Cover your back in the worst-case scenario with the techniques in this tutorial. Learn how to protect yourself from losing huge amounts of critical data.

Ever wish you had a place to let your Linux applications playwhere they wouldn't hurt anything else? Do your killer apps spend too much time killing each other? Originally conceived as a kernel developer's tool, UML lets you set up multiple virtual machines that are isolated from each other and from the hardware. Now you can test applications all the way to failure without breaking the host systemor even requiring a reboot. Veteran administrator Carla Schroder shows you how.

Earlier we learned the basic techniques for using Cascading Stylesheets (CSS) to display XML in browsers. Now let's look at some tricks, traps, and nuances.

See how they pass parameters that not only determine the properties to analyze but also change the desired criteria using Web-based forms.

If you're a programmer who wants to learn how to use PHP to build Web-based applications, start here. Begin with the most basic PHP script, end up working with databases and streaming from the file system. In this part, we look at the basics of building a PHP script, including syntax, HTML forms, and database connections.

This tutorial explains how to use Ajax with PHP and introduces the Simple Ajax Toolkit (Sajax), a tool written in PHP that lets you integrate server-side PHP with JavaScript that makes this work.

Using easy-to-follow, step-by-step instructions, this tutorial samples some of the visual UML 2.0 modeling capabilities. By the end, you'll know how to create a variety of different UML 2.0 diagrams, import existing modeling projects, and edit models.

Learn to identify design problems in your code with the Code Review tools within Rational Software Architect. This tutorial shows you how to use the Code Review rule engine to highlight low-level and high-level coding and design issues.
