The Characteristics of Data, Information and Knowledge
Data: Raw facts and figures with no meaning. E.g. data coming from a weather station as a series of 1's and 0's before being processed.
Information: Data that has been processed to give it meaning and put into context. E.g. Data from a weather station is processed so that the temperature and pressure can be read.
Knowledge: Applying rules to information which enables decisions to be made. E.g. If the temperature is high you don't need to wear a jumper to the shops.

Indirect Data Sources: Data used for a purpose other than it was intended. E.g. Information about the types of drinks wanted at a school disco was collected, it was used weeks later to decide if a healthy drinks campaign should be mounted as many students chose fizzy drinks which are bad for your teeth.
