Dependable and Secure Database Systems:
Ubiquitous Access, Synchronization, Recovery and Data Security

Subhash Bhalla Curriculm

A possibility of a temporary disconnection of database service exists. It is a common need to permit a participating site to lag behind and re-initialize to full recovery. It is also necessary that active transactions view a globally consistent system state for ongoing operations. We study algorithms for on-the-fly Synchronization and Recovery in Distributed Computing Environment for backup and site-initialization. The algorithms need to be non-blocking in the sense that house-keeping steps do not interfere with ordinary transactions. Similarly, many applications require that user data is protected from accidents.
