Progression from Data to Information to Knowledge
Data: Unprocessed or raw facts; a static set of transactional element, such as 0211102345
Information: Processed data; an aggregation of data that have meaning. For example, a financial analysis report that begins with account number 021-110-2345.
Knowledge: A person's range of information, embracing a wider sphere than information. It includes perception, skills, training, common sense, and expert. For example, a financial analyst might say, "All indicators tell me that I'd better pull out of XYZ stock before year end."
