Abstract
The use of database management systems (DBMS) to
replace conventional file processing systems has dramatically
increased in the past years. Although the use of
DBMSs overcomes many of the limitations of file processing
systems, many important applications require access to
and integration of information among several and often
incompatible DBMSs. In this paper we discuss an approach,
known as the federated database approach, that allows
users and applications to access and manipulate data
across several heterogeneous databases while maintaining
their autonomy. We discuss the requirements and objectives
of a federated database management system, and outline
the major issues and challenges for building and using such
a system. In particular, we address the design issues from
three angles: transaction management, system architecture,
and schema integration. Also, we present a five-step
integration methodology followed by a comprehensive
example to illustrate the concepts and techniques involved
in this integration methodology.
