Historic information

This is information gathered and stored over a period of time. It allows decision makers to draw comparisons between previous and present activities. Historic information can be used to identify trends over a period of time.


This is information created from activities during the current workwindow (day, week or month). In real-time systems this information would be created instantly from the data gathered (for example, the temperature in a nuclear power plant turbine), giving accurate and up-to-date information.


This is information that is created using present and historic information to try to predict the future activities, trends and events relating to the operation of an organisation. An example would be sales figures for a company: if the sales figures are up 10% from those recorded this time last year it might be anticipated that next month’s sales figures will also be up by 10%.
