please could you give me real live examples for application of the four cases of tracking
history or mention a source where those given.
case 1 : yesterday is today --> Report all fact data according to today?s value
constellation of a characteristic and a dependent attribute
case 2 : today is yesterday --> Allow to report the fact not only to today?s but
also according to yesterday?s constellation of characteristics and attribute value
case 3 : historical truth --> Report the data according to the constellation of
characteristics and attribute values that was valid when the data occurred.
case 4 : true yesterday and today --> Report only on the data for constellations
of characteristic and attribute values that existed yesterday and still exist today
Thanks in advance
