A content management system is a computer application that supports the creation and modification of digital content using a common user interface and thus usually supporting multiple users working in a collaborative environment. A web content management (WCM) system 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.
