Determining the Currency of Data
Summary: Proposes a constraint-based model of partial currency orders and copy functions that capture how values are copied across correlated attributes to determine current values without timestamps. Formalizes consistency, pairwise currency, certain-current-query answers and copy-function decision problems, and proves matching upper/lower bounds for combined and data complexity across query languages, highlighting tractable special cases.
