A web content management system (WCM or WCMS) is a CMS designed to support the management of the content of Web pages. Most popular CMSes are also WCMSes. Web content includes text and embedded graphics, photos, video, audio, and code (e.g., for applications) that displays content or interacts with the user.
Such a content management system (CMS) typically has two major components:
A content management application (CMA) is the front-end user interface that allows a user, even with limited expertise, to add, modify and remove content from a Web site without the intervention of a webmaster.
A content delivery application (CDA) compiles that information and updates the Web site.
Digital asset management systems are another type of CMS. They manage such things as documents, movies, pictures, phone numbers, scientific data. CMSes can also be used for storing, controlling, revising, and publishing documentation.
