A Content Management System (CMS) is a computer program that allows publishing, editing and modifying content as well as maintenance from a central interface. Such systems of content management provide procedures to manage work flow in a collaborative environment. These procedures can be manual steps or an automated cascade. CMSs have been available since the late 1990s.
CMSs are often used to run websites containing blogs, news, and shopping. Many corporate and marketing websites use CMSs. CMSs typically aim to avoid the need for hand coding, but madly support it for specific elements or entire pages.
