SharePoint 2013 is a collaboration tool at its heart. Its primary goal is to make it easy for users to find and share information, and there are many features built into SharePoint to facilitate this. SharePoint's library system feature can provide a superior alternative to the traditional file server. SharePoint lists can be an easy-to-design and easy-to-use alternative to sharing spreadsheet files or more formal database tables. Both lists and libraries can be customized and extended to provide enhanced appearances and functionality, such as calendars and discussion boards, to name a couple. All of this collaboration can be done through a browser interface and in some cases through integration with Microsoft Office applications.
