Zusammenfassung

One of the most severe problems related to database evolution is how to reflect in the data level the changes that have occurred in the conceptual schema of a database. This is specially relevant when evolution operations affect ISA relationships. In this paper we present our view of the evolution of ISA relationships, focusing on the artifacts that generate the sentences for changing the data in a consistent way. © Springer-Verlag Berlin Heidelberg 2006.
