This chapter presents a framework that creates, uses, and communicates information whose organizational dynamics allow individuals to perform a distributed cooperative enterprise in public educational environments. The approach presented here assumes Web services (possibly offered over a grid) are the enacting paradigm used to formalize educational interactions as cooperative services on various computational nodes of a network. By examining a case study involving a well known micro-array experiment in the growing field of bioinformatics, this chapter will detail how specific classes of interactions can be mapped into a service-oriented model that can be implemented in a variety of e-learning contexts. This framework illustrated by this case study allows for a sophisticated degree of e-learning that can be applied to a range of local or international contexts.

A framework is proposed that would create, use, communicate, and distribute information whose organizational dynamics allow it to perform a distributed cooperative enterprise also in public environments over open source systems. The approach assumes the Web services as the enacting paradigm, possibly over a grid, to formalize interaction as cooperative services on various computational nodes of a network. A framework is thus proposed that defi nes the responsibility of e-nodes in offering services and the set of rules under which each service can be accessed by e-nodes through service invocation. By discussing a case study, this chapter details how specifi c classes of interactions can be mapped into a service-oriented model whose implementation is carried out in a prototypical public environment.

Scientific experiments are executed through activities that create, use, communicate and distribute information whose organizational dynamics are similar to processes performed by distributed cooperative enterprise units. On this premise, the aim of this article is to discuss how a portal-based approach can support the design and management of cooperative scientific experiments executed with a strong information and communication technologies (ICT) support and in a distributed manner, hence named e-experiments. The approach assumes the Web, Web services and the grid as the enacting paradigm for formalizing e-experiments as cooperative services on various computational nodes of a network. A framework is proposed that defines the responsibility of actors of the e-experiment and of the e-nodes in offering services, as well as the portal architecture through which the e-experiment resources can be accessed. By discussing a case study in the field of bioinformatics, the article shows how an e-experiment can be planned and executed starting from a set of Web services inserted in a portal and invoked upon the possibly underlying grid structure.

Generally True

A framework is proposed that creates, uses, and communicates information, whose organizational dynamics allows performing a distributed cooperative enterprise in public environments, even over open source systems. The approach assumes the web services as the enacting paradigm possibly over a grid, to formalize interactions as cooperative services on various computational nodes of a network. The illustrated case study shows that some portions, both of processes and of data or knowledge, can be shared in a collaborative environment, which is also more generally true for any kind of either complex or resource demanding (or both) interaction that will benefit any of the approaches.

Early Phases

For the foreseeable future, testing will remain the mainstay of software quality assurance and measurement in all areas of software development, including Web services and service-oriented systems. In general, however, testing Web services is much more challenging than testing normal software applications, not because they are inherently more complex, but because of the limited control and access that users of Web services have over their development and deployment. Whereas the developers of normal applications, by definition, have full control over their application until release time, and thus, can subject them to all kinds of tests in various combinations (e.g., integration testing, system testing, regression testing, acceptance testing, etc.), users of Web services can often only test them at run-time after they have already been deployed and put into service. Moreover, users of Web services often have to share access to them with other concurrent users. In order to effectively test Web services under these conditions special measures and approaches need to be taken to enhance their testability. Right from the early phases of development, the testability of services needs to be taken into account and “designed into” services. In this chapter we consider these issues and with the aid of a case study we present a methodology that can be used to enhance the testability of Web services.

Scientific experiments are supported by activities that create, use, communicate and distribute information and whose organizational dynamics is similar to processes performed by distributed cooperative enterprise units. The aim of this chapter is to describe the approach undertaken in the Advanced Lab for Bioinformatics Agencies (ALBA) project to the design and management of cooperative scientific experiments (Bosin et al., 2006). A framework is used that defines the responsibility of computational nodes in offering services and the set of rules under which each service can be accessed by networked nodes through invocation mechanisms in the service-oriented style of computing and collaborating (COOPIS, 2005).

Purpose Any computing architecture cannot be designed with complete confidentiality. As a result, at any point, it may leak the information. So, it is important to decide leakage threshold in any computing architecture. To prevent leakage more than the predefined threshold, quantitative analysis is helpful. This paper aims to provide a method to quantify information leakage in service-oriented architecture (SOA)-based Web services. Design/methodology/approach To visualize the dynamic binding of SOA components, first, the orchestration of components is modeled. The modeling helps to information-theoretically quantify information leakage in SOA-based Web services. Then, the paper considers the non-interference policy in a global way to quantify information leakage. It considers not only variables which interfere with security sensitive content but also other architectural parameters to quantify leakage in Web services. To illustrate the attacker’s ability, a strong threat model has been proposed in the paper. Findings The paper finds that information leakage can be quantified in SOA-based Web services by considering parameters that interfere with security sensitive content and information theory. A hypothetical case study scenario of flight ticket booking Web services has been considered in the present paper in which leakage of 18.89 per cent information is calculated. Originality/value The paper shows that it is practically possible to quantify information leakage in SOA-based Web services. While modeling the SOA-based Web services, it will be of help to architects to identify parameters which may cause the leakage of secret contents.

And Performance

Real time impact in many applications is the subject of a recent field of studies in information systems. Web services are a solution for the integration of distributed information systems that are autonomous, heterogeneous and auto adaptable to the context. This impact can resolve many problems in different systems based on Service Oriented Architecture (SOA) and web services. In this paper, the authors are interested in defining an approach to provide the different needs of self-adaptability of SOA to the context based on workflow, define the real time goal in their approach and show the feasibility and performance evaluation of their approach in an ambulance trajectory case study.
