Model-driven business process recovery

Abstract: A business process attempts to encapsulate the delivery of a sequence of tasks, typically starting from accepting a service request and ending at certain points, such as the completion of the service. We propose a model-driven business process recovery framework that captures the essential functional features representing a business process. The framework utilizes static tracing techniques and a number of heuristics to map source code entities to high-level business process entities. A case study is preformed to recover IBM/spl reg/ WebSphere/spl reg/ Business Integration business processes from IBM WebSphere Commerce code. The experimental result demonstrates the effectiveness of the proposed framework.

Towards a service-oriented MDA-based approach to the alignment of business processes with IT systems: From the business model to a web service composition model

Abstract: In recent years, the automation of business processes has become one of the most prominent and promising uses of Web service technology. Consequently several languages have been created for the execution of business processes, making it possible to define new and more complex services or business processes which are implemented for example by means of Web service composition. Nevertheless, these kinds of languages are not suitable for use in the early stages of the development process of information systems. Special methodologies or techniques are therefore necessary to allow systems analysts to understand services from a business point of view, while facilitating the design and development of Web service composition. In this paper, we present a service-oriented approach to information system development that starts by identifying, through business modeling, the services required by the customers of a business, to make it possible to create a Web service composition model. This model will facilitate the transformation to specific languages for business process execution, thereby reducing the development efforts made in service-oriented applications. The method proposed is illustrated by means of a Web application for the management of medical images, which we have taken as a case study.

A Novel Approach to Decentralized Workflow Enactment

Abstract: Web service orchestrations-expressed in the Web service business process execution language (WS-BPEL or BPEL for short)-are a manifestation of the two-level-programming paradigm where services, i.e. the business functions used by the composite application, are composed through BPEL's control flow constructs. BPEL processes Web service orchestrations, business functions therefore can be transparently accessed remotely, allowing to build composite applications that integrate business functions provided by different partners on different locations. As of today, execution of BPEL processes, i.e. the evaluation of the processes' control flow, is performed by a central workflow engine. In certain scenarios, such as complex collaborative cross-partner interactions, this approach of centralized workflow enactment leads to "un-natural" process models; process models that are not driven by the processes' original business goal but by infrastructural or organizational reasons. In this paper, we propose an alternative approach to enacting BPEL process control flow in a distributed, decentralized manner. We present the overall process lifecycle and give a detailed description of the underlying process model.
