A content management system(CMS) is a computer application used to create, edit, manage, and publish content in a consisitently organized fashion. CMSs are frequently used for storing,controlling,versioning, and publishing industry-specific documentation such as news articles,operators’ manuals, technical manuals,sales guides, and marketing brochures(小册子).The content managed may include computer files,image media, audio files, video files, electronic documents, and Web content.
A CMS may support the following features:
identification of all key users and their content management roles;
the ability to assign roles and responsibilities to different content categories or types;

the ability to track and manage multiple versions of a single instance of content;
the ability to capture content(e.g. scanning);
the ability to publish the content to a repository to support access to the content(Increasingly(越来越多地), the repository is an inherent part of the sytem, and incorporates（包含，加上） enterprise search and retrieval.);
