Schema Evolution in Heterogeneous Database Architectures, A Schema Transformation Approach

... 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 ...

Comparing and Transforming Between Data Models via an Intermediate Hypergraph Data Model

... not only a schema, but also the data modelling language in which that schema is represented must be transformed between one data source ... an extension to the hypergraph data model (HDM), used in the AutoMed data integration approach, that allows constraint constructs ...

A General Formal Framework for Schema Transformation

... for integrating database schemas have been proposed in the literature, using various common data models (CDMs). As part of these ... have been defined that map between schemas which are in some sense equivalent. This paper describes a general framework for ...
