A content management system (CMS) is the collection of procedures used to manage work flow in a collaborative environment. These procedures can be manual or computer-based. The procedures are designed to do the following:

• Allow for a large number of people to contribute to and share stored data
• Control access to data, based on user roles (defining which information users or user groups can view, edit, publish, etc.)
• Aid in easy storage and retrieval of data
• Reduce repetitive duplicate input
• Improve the ease of report writing
• Improve communication between users

In a CMS, data can be defined as nearly anything: documents, movies, pictures, phone numbers, scientific data, and so forth. CMSs are frequently used for storing, controlling, revising, semantically enriching, and publishing documentation. Serving as a central repository, the CMS increases the version level of new updates to an already existing file. Version control is one of the primary advantages of a CMS.
