At present, most of the work has focused onWeb services composition from the QoS side, little work being done on investigating how to implement service selection based on transactional and QoS requirements. In complicated network environment, composite services need transactional support for correct and reliable execution. Therefore, how to design a composite service to ensure not only correct and reliable execution but also optimal QoS is a challenging issue. This paper addresses the problem of selecting services by aggregating the transactional and QoS requirements.
