“…Research in the business transactions area is also related to the creation of meta-models for Web service transaction models as for example reported in [13,14]. In [13] the authors propose to combine multiple transaction models as WS-C coordination types into BPEL specifications that can support transactional workflows.…”

“…In [13] the authors propose to combine multiple transaction models as WS-C coordination types into BPEL specifications that can support transactional workflows. In [14] a meta-modeling approach to transaction management is proposed, however, this approach focuses on the modeling and representation of transaction models driven purely from database technology perspective without taking into account business and workflow requirements.…”

Web services technology in support of business transactions

Advanced business applications typically involve well-defined business functions such as payment processing, shipping and tracking, determining new product offerings, granting/extending credit, managing market risk and so on. These reflect commonly standard business functions that apply to a variety of application scenarios. Although such business functions drive transactional applications between trading partners they are completely external to current Web services transaction mechanisms and are only expressed as part of application logic. To remedy this situation, this paper proposes a business-aware Web services transaction model and support mechanisms, which is driven by common business functions. The model allows expressing business functions such as payment and credit conditions, delivery conditions, business agreements stipulated in SLAs, liabilities and dispute resolution policies. It allows blending these business functions with QoS criteria such as security support to guarantee integrity of information, confidentiality, and non-repudiation.

“…Currently the most important standards are WS-Transaction and more recent but not yet widely used WS-TransactionManagement [39]. In general, there are different transaction models for direct, queued and compensationbased transaction processing [40]. While direct processing is useful for short lived transactions and compensation-based for long lasting, queued processing lays in-between.…”

On the one hand, Web services are increasingly gaining attention. Standardization efforts have improved their stability and range of applications. Composition and coordination techniques for Web services enable an application integration effort beyond loosely coupled systems. On the other hand, medical Web services are covered by the DICOM and HL7 communication protocols and are profiled by the IHE (Integrating the Healthcare Enterprise) technical framework. Standardization is more extensive, most workflows are well defined, and integration is tighter than in most other domains. Nevertheless, so far standardization focused on conventional workflow systems. In an Internet-based medical environment with high security standards, communication is strongly restricted and conventional systems fail to deliver. This paper proposes a modeling process for medical Web services. The IHE patient administration process flow serves as a well defined example. Furthermore, the paper defines requirements of a Web service based middleware for the execution of medical Web services by investigating currently relevant Web service protocols. The technique should enable building medical applications for Internet-based workflow execution. Finally, Biztalk 2004 is used to evaluate the implementation of the analyzed sample functionality.

Abstract. The Web services architecture defines separate specifications for the composition and the coordination of Web services. BPEL is a language for creating service compositions in the form of business processes, whereas the WSCoordination framework defines coordination protocols for distributed activities. In this paper, we investigate the combination of these two aspects to compose coordinated Web services. We argue for a policy-based approach to address this problem and introduce a new model and middleware that enables the flexible integration of diverse coordination types into (existing) process-based Web services compositions.
