Information Integration Overview

Information Integration Overview

Much of the recent development of database systems has been toward capabilities that allow different data sources, which may be databases and / or information resources that are not controlled by a DBMS, to work together in a larger whole. We introduced you to these issues in brief, in "Information Integration". Thus, in "Information Integration", we study important aspects of information integration. We discuss the major modes of integration, including translated and integrated copies of sources called a "data warehouse", and virtual "views" of a collection of sources, through what is called a "mediator".
