Schema mapping as query discovery. In Proceed-

(pp. 77-88).

Data Integration: In this chapter, data integra-
tion means data reconciliation.
Data Warehouse: It contains data defined
in terms of an ontology. These data come from
different heterogeneous sources, are transformed
according to the ontology of the data warehouse
and then reconciled.
Mappings: correspondence relations between
a global schema or ontology and the schemas of
data sources.
Mediator-Based Approach: An approach
integrating multiple data sources which can be
syntactically or semantically heterogeneous while
related to a same domain (e.g., tourism, culture). It
