A content management system (CMS) manages the creation and modification of digital content. These systems typically support multiple users in a collaborative environment, allowing to perform document management with different styles of governance and workflows. Usually the content is a website (or part of it) and the term commonly refers to web content management systems. Web content may include text and embedded graphics, photos, video, audio, maps, and program code (such as for applications) that displays content or interacts with the user. By their nature, CMSs support the separation of content and presentation.
