Frequency of Information


This is information created from data gathered several times a second. It is the type of information created by a real-time system. For example, sensors may be set up to collect temperature and humidity readings in a large commercial greenhouse.  It will be important for that information to be collected constantly because any variation in either the temperature or the humidity could point to the failure of some machinery and an alarm could be sounded to alert the staff.  A very important system exists on modern aircraft where the navigation and flight-control systems are continuously monitoring and making adjustments; another is on a computerised production line where constant monitoring allows the system to correct faults. Obviously many other types of realtime systems exist but a feature of them all will be that they check data continuously.


This is information created at regular timely intervals (hourly, daily, monthly, annually). Different examples of information generated by an organisation are needed at specific periods of time.

  • Annually – On an annual basis a company must submit its report and accounts to the shareholders.
  • Monthly – Banks and credit-card companies produce monthly statements for the majority of their customers.
  • Daily – A supermarket will make daily summaries of its sales and use the product information to update its stock levels and to reorder stock automatically.
  • Hourly – A busy call centre will often update totals for each operator on an hourly basis and give the top employee for the hour some reward.
