Abstract :
The performance is studied of atomic updates across different database management systems (DBMSs). An optimistic concurrency-control algorithm is proposed that allows a subclass of global transactions to concurrently retrieve and update the multiple databases, while it places no restriction on the concurrency-control mechanisms used by each of the local DBMSs, thus maintaining local autonomy
