SharePoint Portal Server creates portal pages for people, information, and organizations. The portal also extends the capabilities of Windows SharePoint Services sites with organization and management tools, and enables teams to publish information in their sites to the entire organization.

Content Management
SharePoint enables a single point of access to multiple systems such as Microsoft Office System programs, business intelligence and project management systems, and existing line-of-business applications, including third-party and industry-specific programs.

Collaboration
Provides a powerful team collaboration environment that enables organizations to aggregate, organize, find, and provision SharePoint sites across the enterprise. SharePoint sites for teams, documents, and meetings can also be extended to customers and partners, augmenting the reach and efficiency of existing collaboration methods.
