Microsoft's SharePoint Server 2010 is a significant improvement over SharePoint 07, providing IT execs with multiple ways to streamline their infrastructure and cut costs.

Based on our hands-on testing of the public beta of SharePoint Server 2010, which was officially released today, this product allows IT departments to run applications such as enterprise search, content management, collaboration and business intelligence on a single platform.

Together with improved Internet site capabilities, SharePoint 2010 means companies can avoid the licensing and training costs associated with separate apps. SharePoint 2010 also offers improved developer and administration capabilities, which will likely speed application creation while easing server management.

We tested beta versions of SharePoint Server, and two related apps, Visual Studio and Office 2010, in a virtualised environment and found that SharePoint Server 2010 is faster and more intuitive than the previous version, Microsoft Office SharePoint Server (MOSS) 2007.

The now-familiar ribbon user interface, introduced with Office 2007, is integrated throughout SharePoint 2010. The beta let me take a complex Word 2010 document with tables and paste it into a SharePoint website without losing any of the original design – and then use identical formatting commands in SharePoint to further refine the layout. By contrast, MOSS offered very limited formatting options.

Microsoft has woven Silverlight (a tool for creating interactive web apps) and AJAX functionality throughout, giving business users easy ways to add rich media and interactivity.

I dropped a Silverlight Web Part onto a page to display a Windows Media Video file (contained in the new video asset library) – something that wasn't possible in the past. Companies can employ this capability to build You-Tube-like sites, but without the need for programming or additional applica-tions.

According to Microsoft, accessibility was a highly requested new feature, and from my testing the company listened. I had no trouble viewing my SharePoint sites and editing them using Internet Explorer 8 on a PC and Safari on a Mac, and viewing them through Safari on an iPhone.

SharePoint Workspace 2010 (formerly Microsoft Office Groove) worked without problem in transferring my documents offline (or creating new ones), letting me make edits, and then synchronising changes once I connected back to my network.
