Abstract
In composite database systems, global transactions are decomposed by
the global transaction manager into several global subtransactions
that are executed at the corresponding component database systems.
This paper shows that the execution and termination of a
global transaction depend on the specified extensional assertions on
the local classes as well as on the given kinds of global requests.
In some cases, a global transaction is supposed to be successful if
exactly one global subtransaction is successfully executed. In
other cases, all global subtransactions have to be successful in
order to commit the global transaction. We discuss various
termination rules for global transactions and thus provide new
insights into a complex problem.
