Schema Evolution publication categorizer

Abstract. There exist several recent approaches that leverages the use
of model transformations during software development. The existence
of different kinds of models, at different levels of abstraction, involves
the necessity of transferring knowledge from one model to another. This
framework can also be applied in the context of metadata management
for database evolution, in which transformations are needed both to
translate schemata from one level to another and to modify existing
schemata. In this paper we introduce the notions of translation rule and
elementary translation which are used within a forward database maintenance
strategy.
