This paper presents a new approach to schema evolution,
which combines the activities of schema integration and schema evolution into one framework. In previous work we have developed a general
framework to support schema transformation and integration in heterogeneous database architectures. Here we show how this framework also
readily supports evolution of source schemas, allowing the global schema
and the query translation pathways to be easily repaired, as opposed to
having to be regenerated, after changes to source schemas.
