Now on IBM developerWorks: The Web's future: XHTML 2.0 -- Over the years, HTML has only become bigger, never smaller, because new versions had to maintain backward compatibility. That's about to change. On 5 August 2002, the first working draft of XHTML 2.0 was released and the big news is that backward compatibility has been dropped -- the language can finally move on. So, what do you as a developer get in return? How about robust forms and events, a better way to look at frames and even hierarchical menus that don't require massive amounts of JavaScript.
Now on IBM developerWorks: Building database applications with WebSphere and DB2 (Tutorial) -- One common use for Web services is the enabling of remote access to DB2 database information. Using parts of a simple commodity trading system, this tutorial teaches you how to select from, insert into, and update a DB2 database from WebSphere Studio and from a Java application. You will then convert this application to a Web service with the help of WebSphere Studio. The tutorial also discusses DB2 user-defined functions and stored procedures.
Now in IBM developerWorks: Process XML using XML Query (Tutorial) -- For years developers have been using SQL to retrieve data from structured sources such as relational databases. But what about unstructured and semi-structured sources, such as XML data? To be viable as a data source, XML needed a means for conveniently retrieving the data. XQuery provides this means, allowing developers to write a statement that both extracts data and (if necessary) structures the results as XML. This tutorial shows you how to use XQuery to retrieve information from an XML file. It also explains the ways in which XPath changes with version 2.0, and what those changes mean for data management.
