Enterprise Content Management
ECM is not a solution consisting of a single technology, tool or technique. Rather, it's the integration of multiple technologies & disciplines into a solution designed to solve a specific problem.
According to AIIM, the Enterprise Content Management Association, ECM consists of technologies used to Capture, Manage, Store, Preserve & Deliver content & documents related to organizational processes. ECM tools & techniques allow you to store your organization's unstructured content, wherever that content exists.
