Locally Consistent Transformations and Query Answering in Data Exchange
Summary: Define 'locally consistent transformations' capturing universal solutions/cores and show they preserve local source neighborhoods, yielding negative results for many data-exchange transformations. From this, derive a neighborhood-based necessary condition for target-query rewritability, robust to aggregates/grouping and two semantics of query answering.
