A Logic-Based Approach to Data Integration

dc.contributor.authorJ. Grant, J. Minkeren_US
dc.description.abstractAn 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. (Also cross-listed as UMOIACS-TR-2000-61)en_US
