Abstract

In Service-Oriented Computing (SOC), a business transaction comprises of several web services provided by multiple enterprises. The transactional behaviour of individual web services must be considered for service selection so that the composition of web services results in a reliable execution. It is difficult for a business analyst to envisage the desired business policies of a process in terms of transactional properties of the corresponding service. Hence, an abstract mechanism that enables the business analyst to specify the transactional properties in a simple manner must be introduced. Towards this objective, it is proposed to express the transactional properties in terms of the recoverability of services. The transactional web services are grouped into different levels of recoverability based on their recovery cost. The estimated recovery costs are empirically verified and validated.
