Microsoft Office Project Server 2007 integrates with the core platform and advanced components of MOSS. MOSS includes several server products and components that are built on the Microsoft Windows SharePoint Services 3.0 platform.
Because PS 2007, MOSS , and related products are built on the common SharePoint Products and Technologies platform, developers can use a common set of development tools and techniques to integrate and extend all of the products.
Components of MOSS
MOSS aggregates services and applications that were previously separate products. For example, the functionality of Microsoft Office SharePoint Portal Server 2003 and Microsoft Content Management Server (MCMS) 2002 are now part of Office SharePoint Server 2007. In addition, MOSS adds new administrative, collaboration, business process management, and business intelligence features along with Excel Web Services, Enterprise Content Management, a common search architecture, and workflow.
