Abstract Transaction Construct: Building a Transaction Framework for Contract-Driven, Service-Oriented Business Processes

摘要

Transaction support is vital for reliability of business processes which nowadays can involve dynamically composed services across organizational boundaries. However, no single transaction model is comprehensive enough to accommodate various transactional properties demanded by these processes. Therefore we develop the Business Transaction Framework, which is built on Abstract Transactional Constructs (ATCs). ATCs are abstract types of existing transaction models that can be composed and executed in a service-oriented transaction framework according to the ATC algebra. By selecting and composing ATCs on demand, flexible and reliable process execution is guaranteed.
