Microsoft SharePoint is made up of a platform for several different kinds of programs. To simplify it, it is a web-based Content Management System used by companies to have a secure place to collaborate and streamline the management and access of data.
Microsoft SharePoint is also a portal to run a company intranet site where information can be accessed by anyone within the organization. Permissions can be assigned to different levels of security based on the corporate infrastructure.
Traditionally we store documents in folders to organize them. The problems we face is when someone makes changes to a document, we do not have any version history of what was changed and who made the changes. With SharePoint, one of the most important features is the version control. It allows you and your coworkers to work simultaneously on a single document, saving previous versions, and tracking updates.
