Abstract
The coordination of distributed services and the integration of data repositories that are maintained by autonomous distributed databases requires flexible transaction management. Recently numerous advanced transaction models have been proposed that extend traditional transaction models by releasing one or more of the classical ACID (atomicity, consistency, integrity, durability) properties of transactions. Advanced transaction processing requires a notation for the specification, a high-level communication mechanism to control the traffic between the different sites as well as a flexible scheduling mechanism. In previous work we have shown how our parallel logic based coordination language V PL can serve as transaction specification language and support reliable communication. The main concern of this paper is to demonstrate that the V PL control constructs for AND/OR concurrency can be employed directly for the scheduling of compensatable and non-compensatable distributed transaction...
