SharePoint Portal Server (SPS) is Microsoft's enterprise-class portal solution. It facilitates collaboration, document management, enterprise consolidation, content targeting, and search across WSS sites, file shares, and intranet sites. SPS technology is built on WSS but gives you some important features not available in WSS, such as aggregated search, categorizing information into topics, personalization, and My Site. This section reviews some of the important integration points between SPS and the EPM solution.
As a convention in this section, the term project workspace refers to a WSS site that has been automatically created for a project when the project is published to Project Server.
