How to Integrate Schema Evolution into the Persistent Garbage CollectionGarbage Collection
Englische Kurzfassung:
Schema evolution is an important functionality in object-oriented database
systems, because persistent objects can exist for a long time during which the
environment may change. Therefore it is often necessary to adapt the objects. In
most cases it is enough to change the values of some attributes, but sometimes also
the types of the objects have to be modified, for example, when attributes have to
be renamed or changed. This modification - called schema evolution - is often not
supported by database systems, because of high implementation effort and
increased run time delays. In this paper we demonstrate a very simple algorithm
for schema evolution that is integrated in the garbage collector of a persistent
object-oriented development environment. Thus, no additional delays are
produced, since garbage collection and schema evolution is done in concert. A
proof-of-concept prototype implementation is operational in the Oberon system.
