Cloud computing will fuel growth in open source software as companies try to manage costs, according to database heavyweight Ingres. Tom Berquist, former managing director of financial powerhouses Citigroup and Goldman Sachs and now CFO of open source database firm Ingres, made the prediction last week. Ingres, the second largest open source company, counts the likes of BAE Systems, Cathay Pacific and Lufthansa among its customers. Berquist said the cloud computing model --of companies' serving applications over the Internet--requires vendors to spend large amounts of cash buying and maintaining servers, telecoms infrastructure and software such as operating systems, Web, application and database servers to support their software as a service (SaaS) operation. He added because SaaS vendors needed to invest in more hardware and software than traditional software vendors--where applications are sold to customers to install on their own ma...

Cloud computing is a computing paradigm in which tasks are assigned to a combination of connections, software and services accessed over a network. This network of servers and connections is collectively known as "the cloud." Computing at the scale of the cloud allows users to access supercomputer-level power. Using a thin client or other access point, like an iPhone, BlackBerry or laptop, users can reach into the cloud for resources as they need them. For this reason, cloud computing has also been described as " on-demand computing ." This vast processing power is made possible though distributed, large-scale cluster computing , often in concert with server virtualization software, like Xen , and parallel processing . Cloud computing can be contrasted with the traditional desktop computing model, where the resources of a single desktop computer are used to complete tasks, and an expansion of the client/server model. To paraphrase Sun Microsystems' famous ad...

<p><strong>In the good old days when building web sites was as easy as knocking up a few <a href="http://www.sitepoint.com/glossary.php?q=H#term_75" class="glossary" title="HTML stands for HyperText Markup Language.">HTML</a> pages, the delivery of a web page to a browser was a simple matter of having the web server fetch a file.

Intended Audience This tutorial is intended for developers who wish to extract data from a database and insert it into XML files so that it can be processed in some way, usually by transforming it into HTML using an XSL file. This method completely splits the presentation layer (i.e. the generation of HTML documents) from the business layer (the application of business rules using a language such as PHP) so that any one of these layers can be modified without affecting the other. In the samples below the code is generic in that no column names are ever hard coded. Data is retrieved from the database as an associative array (a series of 'name=value' pairs), and every element of the array is extracted and transferred to the XML file. The contents of the associative array are therefore governed entirely by the SQL 'select' statement. In the samples below I will show how to deal with data from a single table, and then data from two tables with a one-to-many relation...
