“…BPEL based composition is stateless and hence is not suitable for dynamically composed nested workflows where stateful communication is essential across organizations. The frameworks which depend on BPEL for composition of services (Pires et al 2003;Liu et al 2010;Jiuxin et al 2010) support composition only at design time. In addition, these frameworks require specification of functional parameter values of all the component services prior to the composition process.…”

A key challenge in B2B and B2C applications involving dynamic composition of workflow activities is to ensure their reliable execution, in view of frequent failures in the internet environment where a composed service is executed. Existing approaches for transactional coordination of composite web services, consider forward and backward recovery alone, in order to maintain consistency in the case of failures. However, while achieving reliable execution, service cancellability is important due to the predominance of long running processes in business applications and frequently changing user requirements and business policies. If the execution of a long running process is not cancelled in the case of a changed requirement, the completion of the process results in wastage of resources and the outcome may no longer be useful. Hence, a transactional coordination framework named as Tx-FAITH is proposed to handle the cancellation recovery under the external interruption and cancellation of transactions. Tx-FAITH considers hierarchically composed web services whose components are recursively nested to form a composition and adapts a coordination approach based on context information. The proposed coordination and recovery approach when tested with 200 simultaneous users and with a database size of 0.35 million records, incurs only 10 seconds to process a request.

“…The transactional behaviour type or property does not provide any abstraction for the business analyst to choose a service with an appropriate behaviour. Jiuxin et al (2010) defined conceptionconstrained rules for expressing the business logic of a transaction. In the absence of a suitable abstraction, it is a tough task for the business analyst to express the business requirements in the form of constraint rules.…”

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.
