“…This composition is discussed in the literature with mixed objectives. Some approach a composition as an opportunity to engage in the engineering of protocols enabling web services to be self-connecting (perhaps dynamically at execution) (e.g., Bulton et al, 2003, Singh, 2003VanderMeer et al, 2003;Zeng et al, 2003), while others have postulated higher level programming constructs for orchestrating web services using a workflow metaphor as a basis (Ganesarajah and Lupu, 2002). One umbrella effort to characterize aspects of web services composition is in the standard BPEL4WS.…”

Database Schema Design for a Web Services Supply Chain Manager: Requirements and Proposed Infrastructure

Web services enable the commoditization of computer code components for distributed system execution in crossorganizational platforms via the Internet. At any point in time, the state of a set of composite applications and the web services they are consuming constitutes an instance of a new type of dynamic software supply chain. Proper management of what we refer to as this "web services supply chain" requires seamlessly integrated and automated B2B relationships with responsibilities for procurement, performance monitoring, benchmarking, cost allocation and ongoing relationship maintenance requiring new hybrid organizational infrastructure constructs. To cope with the increased complexity of managing this dynamic supply chain, we elaborate requirements and propose an exemplar database schema design with web-scripts as a means for prespecifying and monitoring organizationally approved patterns of web service invocations. The database research challenges associated with long-running transactions are discussed in our schema design, including reflections of the realities associated with web-script failure, variable quality-of-service (QoS) levels, the share-ability of web-scripts between organizational business processes, the need for continuous updating of web-scripts by agents (human or automated), and the scalability of designs to accommodate evolutionary change.

“…One of the advantages of the use of the service oriented paradigm for a KDD support system is to view the formation of a KDD process as a composition of services. This allows to borrow all the theoretical results on generic web service composition from the literature [8,14]. We define two basic composition service types: those related to generic processes, let call it workflow-like, and those more specifically designed for KDD processes.…”

Knowledge Discovery in Databases (KDD) is a highly complex process where a lot of data manipulation tools with different characteristics can, and in fact have to, be used together in an interactive and iterative fashion, to reach the goal of previously unknown, potentially useful information extraction. In this paper we analyze the major sources of complexity in the framework of network organizations, pointing out the necessity to give support to the user in many different ways and at very different levels of granularity, from the use of a single tool, to the management of whole, distributed, KDD projects. Unfortunately, currently available systems lack to support the users in at least some of these features. We then propose a solution based on the Service Oriented Computing paradigm, arguing that the advantages ofthis paradigm, namely openness, modularity, reusability and transparency, as well as ubiquity, can help in the design of an effective support system for Knowledge Discovery in Databases in network environments.

“…As in the case of BPM, efficient workflow design has been also a challenging problem. Workflow languages [8] consider a workflow as a graph problem, with control flow and data flow described in terms of lines in a graph, and those flows need to be described precisely in a professional manner [9][10], such as in the integrated development environment (IDE) used for software manufacturing. Thus, BPM and workflow design researchers have studied how to design service composition efficiently.…”

Ubiquitous service composition provides new services and applications seamlessly by establishing cooperation among any devices in home networks and any services in service provider networks. Since users can utilize whichever of these entities they want at a particular moment, they will be inspired to determine what kinds of entities they want to use as service components and, by themselves, design how those entities are orchestrated. However, designing a composite service scenario is difficult for the majority of general users because it requires professional skills related to web service technology, data flow, programming languages, etc. In addition, there is the specialized problem of matching the different interfaces of the service components. We are developing a novel scenario design support system that includes Service Flow Information, which adds a semantic description of data flow and control structure for two or more sequential service components in order to generate composite scenarios including those service components. It conceals the above difficulties and flexibly describes the interface binding. We implemented the system and evaluated it in terms of the reusability of interface binding and the user-friendliness for general users.
