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.

The purpose and result is to manage the organization’s unstructured information content, with all its diversity of format and location. The system manages the content related commercial organizations.
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.
Web group content management systems
The web group content management system (mostly known as GMS) is very similar to the WCM, with the main difference being the fulfillment of some specific requirements. These requirements aim to satisfy the needs of groups or small organizations that often have difficulty managing their online image, communicate with their members, plan events, set schedules and assign tasks to internal projects. Typically these tasks are distributed by different tools and the GMS unifies them into one.
Component content management system
In a component content management system (CCMS), the content is stored and managed at the sub-document (or component) level for greater content reuse.
CMS has four main functions:
