Abstract
Accessing and managing data from several existing independent databases pose complex problems that can be classified into platform, DMS, location
and semantic levels. This paper describes a general architecture, a methodology and a CASE environment intended to address the problem of providing users and
programmers with an abstract interface to independent heterogeneous and distributed databases. The architecture comprises a hierarchy of mediators that
dynamically transform actual data into a virtual homogeneous database. Each layer provides a certain kind of independence. The InterDB approach provides a
complete methodology to define this architecture, including schema recovery through reverse engineering, database integration and mapping building. The
methodology is supported by the DB-MAIN CASE tool that helps to generate the mediators and their repository.
