    • Query Answering over Functional Dependency Repairs 

      Galiullin, Artur (University of Waterloo, 2013-09-23)
      Inconsistency often arises in real-world databases and, as a result, critical queries over dirty data may lead users to make ill-informed decisions. Functional dependencies (FDs) can be used to specify intended semantics ...
    • Query Evaluation in the Presence of Fine-grained Access Control 

      Zhang, Huaxin (University of Waterloo, 2008-05-20)
      Access controls are mechanisms to enhance security by protecting data from unauthorized accesses. In contrast to traditional access controls that grant access rights at the granularity of the whole tables or views, ...
