a source and target data source for InfoSphere DataStage jobs.
Source: developerWorks : XML : Technical library As you create cross-platform desktop applications using XUL, you also can
enhance your skills with JavaScript, CSS, and even HTML. XUL's cross-platform
capabilities are not a collection of least common denominator features. Instead,
XUL gives you the kind of power that you might expect from a desktop application
toolkit, including access to native threads. You can even access native threads
directly from JavaScript, writing code that executes in parallel. In this article,
you will examine the multithreading capabilities of XUL, and create an application
that uses multiple threads to retrieve data. You will take a classic IO-bound
application, one that accesses multiple remote data sources over the Internet, and
speed it up through multiple threads in XUL. The application will allow users to
view and compare anonymous results of three popular search engines: Google,
Yahoo, and Bing from Microsoft(R).
Source: developerWorks : XML : Technical library Writing GUIs in program code can often lead to messy design choices, which
in turn results in a blurring between business logic and UI code. Discover how to create a
declarative XML UI tag set with an accompanying Java(TM) framework that parses, validates,
constructs, and finally binds the declared GUI components to business logic at runtime.
Source: developerWorks : XML : Technical library Discover how to leverage XML serialization and XSL-FO to generate dynamic PDF
documents from Java(TM) business objects. Through XSL-FO stylesheets, you can separate the
presentation (view) of data from the data and Java code, allowing for modifications to PDF
format and layout without changes to the Java code.
Source: developerWorks : XML : Technical library DB2 introduced pureXML technology in Version 9. This technology allows you to store XML data in its native
form, maintaining the hierarchical structure and permitting you to query it using SQL/XML and XQuery. Just as with relational data, the ability to
ensure the integrity of XML data stored in DB2 is mandatory. The methods and mechanisms for ensuring the integrity of XML data, however, are a bit
different than the methods for traditional relational data integrity.
In this article, you'll learn about XML data integrity in the context of DB2, and explore the various options you have to guarantee integrity in
different scenarios.

Source: developerWorks : XML : Technical library Today, there is a great deal of interest in energy, and its less-desirable
environmental shadow, carbon dioxide. To create a more sustainable world,
individuals, companies, and governments are focusing attention on energy and how
we use it. The route to understanding our usage of energy (and therefore carbon)
is to measure and analyze it, to understand the results, and then act on that
information. AMEE is a neutral aggregation platform for all forms of energy and
activity data, and associated carbon models. In this article, you learn how to use the AMEE platform in your applications to deliver a high quality energy management and carbon calculation solution to your clients.

Source: developerWorks : Open source : Technical library Developing for mobile devices has been a high cost, low return
proposition for many years, despite the hype around it. The latest generation
of smartphones powered by the iPhone OS and Google's Android provide a much
simplified solution: just build Web applications. This gives you a one build for
