For the demonstration network, it is envisaged to set up an automatic procedure checking that data and their variations are within meaningful ranges. This quality check does take a little time, which means that there is a small delay between the collection of data and their display. Hence, the term near real-time data . When data has been checked they are stored in a database from which they are published on the Internet so they can be accessed by a web browser, downloaded etc. However, it is not necessarily the raw data themselves that are published.
Most users prefer some digestion of the data in the form of filtering, processing , or mapping.
At the very least, some graphical mapping of the data as curves, diagrams, or animations is needed. However, even further interpretation is often needed, for example, by giving alarms when critical combinations of data are found or by providing other forms of decision support. Data mining technology is becoming increasingly useful for practical applications. It is, for example, possible to reveal long-term trends in a data set that might not otherwise be visible. The database is organized to give different access rights to different groups of users.
