Data integration is the problem of combining data residing
at di‹erent sources, and providing the user with a unified
view of these data. The problem of designing data integra-
tion systems is important in current real world applications,
and is characterized by a number of issues that are interest-
ing from a theoretical point of view. This document presents
on overview of the material to be presented in a tutorial on
data integration. The tutorial is focused on some of the the-
oretical issues that are relevant for data integration. Special
