Schema Evolution publication categorizer

This paper describes the AutoMed repository and some asso-
ciated tools, which provide the first implementation of the both as view
(BAV) approach to data integration. Apart from being a highly expressive data integration approach, BAV in additional provides a method to
support a wide range of data modelling languages, and describes transformations between those data modelling languages. This paper documents
how BAV has been implemented in the AutoMed repository, and how
several practical problems in data integration between heterogeneous

Data integration is frequently performed between heterogeneous data sources, requiring that not only a schema, but also the data modelling language in which that schema is represented must be transformed between one data source and another.
