| Abstract: | An important aspect of data integration involves answering queries
using various resources rather than by accessing database relations.
The process of transforming a query from the database relations to the
resources is often referred to as query folding or answering queries
using views, where the views are the resources. We present a uniform
approach that includes as special cases much of the previous work on
this subject. Our approach is logic-based using resolution. We deal
with integrity constraints, negation, and recursion also within this
framework.
