Trying to Cater for Replication Consistency and Integrity of Highly Available Data

Replication increases the availability of data. Availability, consistency and integrity are competing objectives. They need to be reconciled, and adapted to the needs of different applications and users, by appropriate replication strategies. We outline work in progress on a middleware architecture for replicated databases. It simultaneously maintains several protocols, so that it can be reconfigured on the fly to the actual needs of availability, consistency and integrity of possibly simultaneous applications and users
