In this paper, we clarify the concept of FDs in probabilistic relations and present an efficient chase algorithm LPChase(r, F) for maintaining consistency of a ...
The problem of maintaining consistency via functional dependencies (FDs) has been studied and analyzed extensively within traditional database settings.
