How is Content Management different from Document Management ?
Content is the actual units of information, this could be a chart, a diagram, a table or text. A specific document could be a collection of these content units, in fact a given version of a document will contain a specific version of these content units. In a simple case a document may contain only one content unit, however in large documents (e.g. Instruction Manual) it is usual to have a number of text content units and several diagram content units. Document Management is about managing the Documents in terms of versions, access control, distribution, etc. whereas Content Management is about managing the content units in terms of versions, access control, re-use, etc. So Content Management separately manages the content from the presentation whereas Document Management controls the content and presentation as a pair.
