Data Storage

There are three different types of data storage in ProviewR, trends, fast curves and historical
data storage. Trends are storing data cyclic during a shorter period of time in the realtime
database. Fast curves are triggered by some event and stores data for a period of time after
the trigg event, and in some cases also before. The historical storage is made on disk in a
relation database and is able to cyclically store data in several years.
