In this paper, we present an approach to easily define flexible and reliable services compositions. We introduce a new concept called transactional patterns to specify flexible and reliable composite Web services. A transactional pattern is a convergence concept between workflow patterns and advanced transactional models. It can be seen as a coordination pattern and as a structured transaction....

A major challenge of Transactional memory implementations is dealing with memory accesses that occur outside of transactions.

However, we did not capture non-transactional memory accesse...
