Modeling and Execution of Multienterprise Business Processes
We discuss a fully featured multienterprise business process plattform
(ME-BPP) based on the concepts of agent-based business processes. Using the
concepts of the subject-oriented business process (S-BPM) methodology we
developed an architecture to realize a platform for the execution of
distributed business processes. The platform is implemented based on cloud
technology using commercial services. For our discussion we used the well known
Service Interaction Patterns, as they are empirically developed from typical
business-to-business interactions. We can demonstrate that all patterns can be
easily modeled and executed based on our architecture. We propose therefore a
change from a control flow based to an agent based view to model and enact
business processes.Comment: arXiv admin note: substantial text overlap with arXiv:1404.273
Can Component/Service-Based Systems Be Proved Correct?
Component-oriented and service-oriented approaches have gained a strong
enthusiasm in industries and academia with a particular interest for
service-oriented approaches. A component is a software entity with given
functionalities, made available by a provider, and used to build other
application within which it is integrated. The service concept and its use in
web-based application development have a huge impact on reuse practices.
Accordingly a considerable part of software architectures is influenced; these
architectures are moving towards service-oriented architectures. Therefore
applications (re)use services that are available elsewhere and many
applications interact, without knowing each other, using services available via
service servers and their published interfaces and functionalities. Industries
propose, through various consortium, languages, technologies and standards.
More academic works are also undertaken concerning semantics and formalisation
of components and service-based systems. We consider here both streams of works
in order to raise research concerns that will help in building quality
software. Are there new challenging problems with respect to service-based
software construction? Besides, what are the links and the advances compared to
distributed systems?Comment: 16 page
Digital Preservation Services : State of the Art Analysis
Research report funded by the DC-NET project.An overview of the state of the art in service provision for digital preservation and curation. Its focus is on the areas where bridging the gaps is needed between e-Infrastructures and efficient and forward-looking digital preservation services. Based on a desktop study and a rapid analysis of some 190 currently available tools and services for digital preservation, the deliverable provides a high-level view on the range of instruments currently on offer to support various functions within a preservation system.European Commission, FP7peer-reviewe
THE (LACKING) BUSINESS PERSPECTIVE ON SOA – CRITICAL THEMES IN SOA RESEARCH
Service-oriented architecture (SOA) has gained much popularity lately, in both practice and academia. Since SOA concepts and technology are maturing, companies have started to engage in projects that will fundamentally transform IS landscapes over the next decade. While the growing body of SOA research is mostly technology-oriented, the IS community needs to investigate the strategic, organizational, and managerial issues associated with SOA implementation. This paper profiles SOA and Web services research since 2000 with a focus on practices, adoption, and impact. Drawing on a sample of 175 papers in academic journals and conference proceedings, we establish transparency of the current state of research. Our analysis finds that the science base for SOA research from an IS perspective is still under construction thereby reflecting the novelty of the underlying technologies. We conclude that business aspects remain underserved and derive a number of recommendations for the IS community on how to proceed with SOA research
Multinational perspectives on information technology from academia and industry
As the term \u27information technology\u27 has many meanings for various stakeholders and continues to evolve, this work presents a comprehensive approach for developing curriculum guidelines for rigorous, high quality, bachelor\u27s degree programs in information technology (IT) to prepare successful graduates for a future global technological society. The aim is to address three research questions in the context of IT concerning (1) the educational frameworks relevant for academics and students of IT, (2) the pathways into IT programs, and (3) graduates\u27 preparation for meeting future technologies. The analysis of current trends comes from survey data of IT faculty members and professional IT industry leaders. With these analyses, the IT Model Curricula of CC2005, IT2008, IT2017, extensive literature review, and the multinational insights of the authors into the status of IT, this paper presents a comprehensive overview and discussion of future directions of global IT education toward 2025
