Abstract: Changing a database schema may affect the preexistent data instances and programs. Two major strategies has been followed to deal with schema changes side effects on data and programs. The first, called data restructuring consists in converting data to render them conform to the modified schema. However it doesn't concern the programs. The second approach allows the coexistence of several schema versions into the same database. Such an approach uses the emulation mechanism to achieve programs... (Update)
