Between Service Science and Service-Oriented Software Systems

Innovations in Information Technology ( …, 2012

Service-oriented software engineering (SOSE) is a software engineering approach for building service-oriented solutions by utilizing service-oriented computing paradigm constructs and concepts. Different methods exist to develop service-oriented software. However, no standardized set of service-oriented principles has been defined yet. This paper surveys current principles and provides a comparison framework to identify which are most considered by different SOSE methods at various stages of solution life cycle.

Context: The use of a Service Oriented Architecture (SOA) offers a new and distinct approach to creating software based applications (SBAs) around the idea of integrating distributed autonomous computing resources. A widely available realisation of an SOA exists in the form of web services. However, to date no standard techniques have emerged for developing SBAs. There is also a lack of consistency in describing the concept itself, and the published literature offers little evidence derived from the experience of developing `real world examples. Aims: The objective of the work described in this thesis was to conduct a series of studies to explore systematically the concept of what constitutes an SOA by using the published literature, to employ this to construct a proof of concept SOA design model based on a real world problem, and in doing so, to investigate how well existing design notations are able to support this architectural style. Method: The research described in this thesis...

Service-Oriented Architecture (SOA) constitutes a modern, standards-based and technology-independent paradigm and architectural style for distributed enterprise computing. The SOA style promotes the publishing, discovery, and binding of loosely-coupled, network-accessible software services. With SOA systems operating in distributed and heterogeneous execution environments, the engineers of such systems are confined by the limits of traditional software engineering. In this position paper, we scrutinize the fundamental tenets underpinning the development and maintenance of SOA systems. In particular, we introduce software service engineering as an emerging discipline that entails a departure from traditional software engineering disciplines, embracing the 'open world assumption'. We characterize software service engineering via seven defining tenets. Lastly, we survey related research challenges.

Service-oriented software engineering (SOSE) aims to design, develop and maintain service oriented applications in a systematic approach. Due to the complexity that is introduced when software programs as services can be discovered, composed, instantiated, executed at runtime, SOSE poses new challenges in the way software is engineered as opposed to traditional software systems. In order for service-oriented systems to succeed, a well focused SOSE research agenda is needed. This paper proposes a model that can help researchers to identify the novelty of SOSE challenges and their research scope, and thus further helps to build the SOSE research agenda. To give an example of how to apply the proposed model, this paper explores the SOSE challenges that relate to business benefits by presenting a worked out instance of the model.

In this article we review the metaphor of service-oriented architecture for enterprise computing. In typical definitions service-oriented architecture appears as a single message and a consistent roadmap for building flexible software system landscapes. But it is not. Different communities have elaborated different SOA (service-oriented architecture) concepts to address different problem areas, i.e., enterprise application integration, business-to-business, business process management, and software productizing. If software architects and software managers are aware of these strands of SOA when talking about SOA in their projects they can avoid misunderstandings and detours better. This article contributes a clarification of the different strands of SOA concepts and technologies and their mutual dependencies and identifies particular SOA concepts as instances of more general software engineering principles.

Service-oriented Computing and Service-oriented Architec- tures aspire to better exploit existing middleware technologies. To this end, a more exible, platform independent software design methodol- ogy is suggested, to develop rapid, low cost, interoperable, evolving and massively distributed software systems. Intended application areas in- clude electronic commerce, information systems, supply chain control, and many other areas. Time is ripe to underpin this eort by theoretically well-founded concepts to model services, and to analyze such models. In this paper we suggest rst proposals and principles for a comprehensive theory of services.

Service-Oriented Architecture (SOA) constitutes an important, standards-based and technology-independent distributed computing paradigm and architectural style for discovering, binding, assembling, and publishing loosely-coupled and network-available software services. With SOA-enabled applications operating in highly complex, distributed, and heterogeneous execution environments, SOA practitioners encounter the limits of traditional software engineering. In this Dagstuhl seminar, we have discussed and explored the fundamental tenets underpinning the development and maintenance of SOA systems. As a result of our discussions, we position software service engineering as an evolving and converging discipline that embraces the open world assumption. Software service engineering entails a departure from traditional software engineering disciplines such as component-based development, supplementing them with techniques and patterns tailored to service enablement, composition, and management.

Service-oriented System Engineering (SOSE) is one of the emerging research areas that involves a number of research challenges in engineering service-oriented systems, the architecture and computing paradigm as well as the development and management of service-oriented systems. Service-Oriented Computing (SOC) exploits services as the fundamental elements for developing computer-based systems. It has been applied to various areas and promotes fundamental changes to system architecture, especially changing the way software systems are being analyzed, architected, designed, implemented, tested, evaluated, delivered, consumed, maintained and evolved. The innovations of SOC also offer many interesting avenues of research for scientific and industrial communities. In this paper, we present the concepts of the SOSE from the related work. The motivation, opportunities and challenges of the SOSE is highlighted thereafter. In addition to this, a brief overview of accepted papers in our Special Issue on SOSE is presented. Finally we highlight and summarize this paper.

The rationale behind service oriented computing is to lift inter-organisational integration on a higher level of effectiveness and efficiency. E-services promise to offer means for floating modularisation of arbitrary organisational assets into components that can be dynamically offered, discovered, negotiated, accessed and composed in an open environment. From a technical point of view electronic services are software systems that have
