Definition
Atelic data is temporal data describing facts that do not involve a goal or culmination. In ancient Greek,
telos means “goal,” and α is used as prefix to denote negation. In the context of temporal databases, atelic data is that data for which both
upward and
downward (temporal)
inheritance hold. Specifically,
Downward inheritance. The downward inheritance property implies that one can infer from temporal data d that holds at valid time t (where t is a time period) and that d holds in any subperiod (and sub-point) of t.
Upward inheritance. The upward inheritance property implies that one can infer from temporal data d that holds at two consecutive or overlapping time periods t1 and t2 and that d holds in the union time period t1 ∪ t2.
Atelic data is differentiated from telic data, in which neither upward nor downward inheritance holds.
