A content management system (CMS) allows publishing, editing, and modifying content from a central page. It provides procedures to manage workflow collaboratively, either manually or via computer. A CMS features include web-based publishing using templates, format management, revision control, indexing and search. It defines data that can be contributed and stored, and controls access and data validity. While a CMS provides benefits like easier maintenance and SEO, it also requires computer skills and resources to implement and maintain properly.
