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.
