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 set up on specific pages. For example, a department can set up 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 are password protected sites a business would want accessed outside of the building. Internet sites would allow for the management of a company's external website.
