First introduced in 2001, Microsoft SharePoint is a web based business platform used for document management and content management. SharePoint allows permissions to be assigned to a page of content. SharePoint integrates specifically to Active Directory, which is the Microsoft management tool for these lists. Different functions can be setup on specific pages. For example, a department can setup a team calendar to track who is currently on call. Another page can contain forms which employees need to fill out, perhaps for a vacation time request. Keeping official documents for policy and procedure in one site that can be accessed from the Internet also allows for continuity in knowledge.
Visio can also offer intranet portals that offer content and applications within a company; extranet sites – which are password protected sites a business would want accessed outside of the building; and Internet sites – which would allow for the management of a company's external website.
