A schema mapping is a specification that describes how data structured under one schema (the
source schema) is to be transformed into data structured under a different schema (the target
schema). The data exchange problem is to take an instance of the source schema and transform it
into an instance of the target schema such that the schema mapping is satisfied.
We investigate several research issues that arise in this framework.
