CMS (Content Management System)
Content Management refers to the arrangement of all available information within the company. Attention is rivetted more on electronic files than on documents. By default, versions and content of Office files, for instance, are managed in a central application.
Some Content Management Systems (CMS) contain a Document Management System, others simply follow the data-committed approach to information acquisition and processing in the company. Some Content Management Systems help joint working on HTML documents and websites.
An Enterprise Content Management System (ECM) on the other hand manages all documents generated in a company. It typically includes the functions of a digital archive and complements them with workflows, version control, Check-In / -Out and much more.
