Content management, or CM, is the set of processes and technologies that support the collection, managing, and publishing of information in any form or medium. There are many types of content management systems (CMS) that include a wide variety of functions in addition to content management. Categories of content management systems include Enterprise Content Management (ECM),  Web Content Management (WCM), and Digital Asset Management (DAM). 

Most CMSs are currently marketed as “Digital Experience Management” (DEM or DXM), and “Customer Experience Management” (CEM or CXM or DXP) systems or platforms, and may include additional marketing technology functions.
