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 (the user roles define which information each user can view or edit)
- 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.
Enterprise content management systems
An enterprise content management system (ECM) is concerned with content, documents, details and records related to the organizational processes of an enterprise. The purpose and result is to manage the organization's unstructured information content, with all its diversity of format and location.
Web content management systems
A web content management (WCM) system is a CMS designed to simplify the publication of web content to web sites and mobile devices—in particular, allowing content creators to submit content without requiring technical knowledge of HTML or the uploading of files.
Several web-based content management systems exist both in the Open Source and commercial domains.
