Abstract

I will discuss two fundamental problems in information integration: (1) how to answer a query over a public interface which combines data from several sources and (2) how to create a single database conforming to the public interface which combines data from several sources. I consider the case where the sources are relational databases, where the public interface is a public schema (a specification of the format of a database), and where the sources are related to the public schema by a mapping that is specified by constraints.
