Abstract: The use of meta-level architectures for the implementation of faulttolerant systems is today very appealing. Nevertheless, all existing fault-tolerant systems based on th...
The primary-backup replication model is one of the commonly adopted approaches to providing fault tolerant data services. Its extension to the real-time environment, however, impo...
A major cost in executing queries in a distributed database system is the data transfer cost incurred in transferring relations (fragments) accessed by a query from different site...
Checkpointing and rollback recovery is a very effective technique to tolerate transient faults and preventive shutdowns. In the past, most of the checkpointing schemes published i...
