Abstract
This paper reviews the development and changes in the processing of large volumes of unstructured information. Author focuses on Enterprise Content Management (ECM) system and identifies three periods of its evolution. During this time ECM evolved to be high-quality and widely available technology, but many organisations have still not implemented ECM systems. The paper contains findings of a survey about the barriers and benefits of adoption of ECM systems, conducted in February 2010 in various organisations in Czech Republic.
