In temporal databases some attribute values depend on the associated timestamps while other attribute values are independent of them. An attribute is temporally independent if it has a value for a given time period and if this value also holds for periods contained in the original period. In contrast, the value of a temporally dependent attribute holds for the given time period only. Different values hold for its sub-periods. The completed database provides information for each sub-period of a database fact. In this paper we extend ATSQL to support temporally dependent information and report experiences from a prototype implementation.
