Microsoft Office Live Small Business is built on Microsoft Windows SharePoint Services 3.0 technology however, you work with them in slightly different ways.
In Windows SharePoint Services you can define a custom site by using a site definition or a custom template. Site definitions consist of multiple files on a front-end Web server that contain XML tags that define a template for a site. Custom templates are created through the user interface or through the object model, and are stored in the database.
However, site definitions and the object model are not accessible to Office Live Small Business developers. Additionally, custom sites that you create and save as a template by using the Windows SharePoint Services interface may encounter problems when uploaded to Office Live Small Business, because these sites do not support Office Live Small Business navigation features. For these reasons, it is recommended that you start with an Office Live Small Business template to create an application or workspace. For more information, see How to: Choose a Template.
Server-side programs that implement the Windows SharePoint Services object model will not work with Office Live Small Business. However, you can use Windows SharePoint Services Web services and Remote Procedure Call (RPC) methods to work with them remotely. For more information, see the following:
