Abstract:Current web-services technology and standards provide minimal
support for creating reliable, meaningful e-business
applications. It only provides rudimentary mechanisms for
appropriately connecting together and coordinating complex,
long-lived business activities performed on the basis of web
services.
To remedy this situation, we propose to develop a conceptual
transaction model and support mechanisms for advanced transactional
behavior of complex service-oriented business processes that span
organizations. The model allows expressing unconventional atomicity
criteria, e.g., payment atomicity, conversation atomicity, contract
atomicity, and possesses the ability to express collaborative
agreements and business conversation sequences that rely on
transactional support. The model relies on a phased approach to
business transactions so that all exchange of information between
partners on the terms they could commit to, e.g., to fix price and
quantity, are kept outside the "pure" transaction protocol. This
results in enhancing flexibility and reducing latency and expensive
transaction compensations and rollbacks in business interactions.
