Abstract
This paper focuses on the interoperability of autonomous legacy databases with the idea of meeting the
future requirements of an organization. It describes a general architecture and a methodology intented to address
the problem of providing new client applications with an abstract interface defined from the new requirements and
the description of the legacy databases. The architecture relies on a hierarchy of mediators that provide the abstract
interface of the new system. The methodology integrates the processes of standard database forward design, data-base
reverse engineering and database federation. The discussion is illlustrated by a small case study.
