Traditional organizational structures evolve towards online business using modern IT – such as cloud computing, semantic standards, and process- and service-oriented architectures. On the technology level, Web services are dominantly used for modeling the interaction points of complex Web applications. So far, development of Web services has matured on the technical perspective considering for example the development of standards for message exchanges and service coordination. However, business concepts, such as economic assets exchanged in transactions between cooperating actors, cannot be easily traced in final Web service specifications. As a consequence, business and IT models become difficult to keep aligned. To address this issue, the authors propose an MDD approach to elicit business services and further software services using REA business model as the starting point. The proposal focuses on a value-explorative elicitation of business services at the top level and model transformations using UML 2 to the system level by utilizing well-defined mappings.

Contemporary enterprises face strong pressures to increase competitiveness by engaging in alliances of several kinds. In a rapidly increasing degree, traditional organizational structures evolve towards online business using modern ICT – such as the Internet, semantic standards, process- and service-oriented architectures. For efficient applications of inter-organizational information systems, the alignment between business and ICT is a key factor. At the ICT level, Web services are used as the cornerstones for modeling the interaction points of Web applications. So far, development of Web services has focused on a technical perspective, such as the development of standards for message exchanges and service coordination. Thereby, business concepts, such as economic values exchanged among the cooperating actors, cannot be traced in Web service specifications. As a consequence, business and ICT models become difficult to keep aligned. To address this issue, the authors propose a MDA-based approach for design of software services which may be implemented using Web services and Web service coordinations. The proposal focuses on a value-explorative analysis and modeling of business services at the CIM level, and model transformations using UML 2 to the PIM level, by utilizing well-defined mappings.

Service-Oriented Architectures (SOA) enable the automatic creation of business applications from independently developed and deployed Web services. As Web services are inherently a priori unknown, how to deliver reliable Web services compositions is a significant and challenging problem. Services involved in an SOA often do not operate under a single processing environment and need to communicate using different protocols over a network. Under such conditions, designing a fault management system that is both efficient and extensible is a challenging task. In this article, we propose SFSS, a self-healing framework for SOA fault management. SFSS is predicting, identifying, and solving faults in SOAs. In SFSS, we identified a set of high-level exception handling strategies based on the QoS performances of different component services and the preferences articled by the service consumers. Multiple recovery plans are generated and evaluated according to the performance of the selected component services, and then we execute the best recovery plan. We assess the overall user dependence (i.e., the service is independent of other services) using the generated plan and the available invocation information of the component services. Due to the experiment results, the given technique enhances the service selection quality by choosing the services that have the highest score and betters the overall system performance. The experiment results indicate the applicability of SFSS and show improved performance in comparison to similar approaches.

Service Oriented

Highly developed economies are based on the knowledge society. A variety of software tools are used in almost every aspect of human life. Service-oriented architectures are limited to corporate-related business solutions. This chapter proposes a novel approach aimed to overcome the differences between real life services and software services. Using the design approaches for the current service-oriented architecture, a solution that can be implemented in open source systems has been proposed. As a result, a new approach to creating an agent for service composition is introduced. The agent itself is created by service composition too. The proposed approach might facilitate the research and development of Web services, service-oriented architectures, and intelligent agents.

In this data-centric world, as web services and service oriented architectures gain momentum and become a standard for data usage, there will be a need for tools to automate data retrieval. In this paper we propose a tool that automates the generation of joins in a transparent and integrated fashion in heterogeneous large databases as well as web services. This tool reads metadata information and automatically displays a join path and a SQL join query. This tool will be extremely useful for performing joins to help in the retrieval of information in large databases as well as web services.

Technology Trends

Service-oriented architectures (SOA), mostly based on Web services (W3C), provide an industrial standard for deploying, publishing, discovering, and invoking enterprise’s services. From its emergence, many specialists have predicted that SOA will revolutionize the distributed computing paradigm and it will make various kinds of e-business (e.g., virtual enterprises, inter-enterprise collaboration, and ASP paradigms) a reality. This article examines the service-oriented architectures (SOA) applied to innovative organization schemes such as virtual enterprises (VE) to resolve the enterprise organizational structure integration problem. The evolution of software architectures from traditional to SOA is presented, along with the characteristics, advantages and disadvantages, and problems and difficulties in applying the SOA, while also focusing on the compatibility between SOA and modern organizational structures. The new standard in the service orchestration level BPEL is considered as a language for business process modelling and its impact to the integration problem is examined. New messaging protocols and frameworks such as the enterprise service bus (ESB) or messaging service bus are also examined. The main focus is on the SOA technology trends of modern organizational structures with regards their formation and integration. The comparison between SOA and traditional architectures provides a clear path to their adoption in various cases.
