    In addition to producing a pervasive standard and atechnology framework, the Web Service initiative hasprompted businesses to re-examine their service deliverychannels. Back-end systems are already in place tocapture business knowledge and manage operationalstrategies and procedures. Web Services enable access tosuch systems, as well as basic orchestration. Theinfrastructure is in place to recreate the business-levelnotion of an electronic service. However, the gap betweentechnology-oriented and business-oriented models forservices is still considerable.In this paper, we outline a model for electronic servicesas defined by the FRESCO project. The model constitutesan architectural blueprint of the technical and businessinfrastructure for an electronic service. The focus is onthe provisional aspects of electronic services

    The ability to rapidly find potential business partners as well as rapidly set up a collaborative business process is desirable in the face of market turbulence. Collaborative business processes are increasingly dependent on the integration of business information systems. Traditional linking of business processes has a large ad hoc character. Implementing situational enterprise services in an appropriate way will deliver the business more flexibility, adaptability and agility. Service-oriented architectures (SOA) are rapidly becoming the dominant computing paradigm. It is now being embraced by organizations everywhere as the key to business agility. Web 2.0 technologies such as AJAX on the other hand provide good user interactions for successful service discovery, selection, adaptation, invocation and service construction. They also balance automatic integration of services and human interactions, disconnecting content from presentation in the delivery of the service. Another Web technology, such as semantic Web, makes automatic service discovery, mediation and composition possible. Integrating SOA, Web 2.0 Technologies and Semantic Web into a service-oriented virtual enterprise connects business processes in a much more horizontal fashion. To be able run these services consistently across the enterprise, an enterprise infrastructure that provides enterprise architecture and security foundation is necessary. The world is constantly changing. So does the business environment. An agile enterprise needs to be able to quickly and cost-effectively change how it does business and who it does business with. Knowing, adapting to diffident situations is an important aspect of today’s business environment. The changes in an operating environment can happen implicitly and explicitly. The changes can be caused by different factors in the application domain. Changes can also happen for the purpose of organizing information in a better way. Changes can be further made according to the users' needs such as incorporating additional functionalities. Handling and managing diffident situations of service-oriented enterprises are important aspects of business environment. In the chapter, we will investigate how to apply new Web technologies to develop, deploy and executing enterprise services

    Evaluating the Performance and Quality of Web Services in Electronic Marketplaces

    Get PDF
    A Web service is a software interface that describes a collection of operations that can be accessed over the network through standardized messaging. Effective performance and quality measures of Web services on Web service electronic marketplaces should include both technical and business aspects and consider Web services as business services delivered through multiple channels. In this research, we integrate technical measures of e-service performance with established measures for evaluating service quality in a business. This integrated view of Web service performance is lacking in extant knowledge and is critically needed to evaluate the overall quality and performance of business environment where information services are delivered through Web services

    An Exploratory Study of Web Service Adoption

    Web Services have the potential to facilitate applications and information to be delivered over the Internet, which can be accessed by disparate devices from handhelds to large servers. Web Services offer a company the capability of conducting business electronically with potential business partners in a multitude of ways at a reasonable cost. Web Services technology is an emerging technology. As a result, there exists some technical papers in Web Services, but behavioral and attitudinal aspects toward Web Services have not been explored. To address behavioral issues, we apply diffusion theory (Moore and Benbasat 1991) and security related research in technology adoption and propose a model. Nine hypotheses are proposed

    How do goals drive the engineering of capacity-driven Web services?

    This paper discusses a goal-based approach for the engineering of capacity-driven Web services. In this approach goals are set to define the roles that these Web services could play in business applications, to frame the requirements that could be put on these Web services, and to identify the processes in term of business logic that these Web services could implement. Because of the specificities of capacity-driven Web services compared to regular (i.e., mono-capacity) Web services, their engineering in terms of design, development, and deployment needs to be conducted in a complete different way. A Web service that is empowered with several capacities, which are basically operations to execute, has to know which capacity it can choose from several capacities for triggering at run-time. For this purpose, the Web service takes into account different types of requirements like data and privacy that are put on each capacity empowering this Web service. In addition, this paper shows that the goals in the approach to engineering capacity-driven Web services are geared towards three aspects, which as business logic, requirement, and capacity. © 2010 IEEE

    Fierce competition in a market increasingly crowded and frequent changes in consumer requirements are the main forces that will cause companies to change their current organization and management. One solution is to move to open architectures and virtual type, which requires addressing business methods and technologies using distributed multi-agent systems. Intelligent agents are one of the most important areas of artificial intelligence that deals with the development of hardware and software systems able to reason, learn to recognize natural language, speak, make decisions, to recognize objects in the working environment etc. Thus in this paper, we presented some aspects of smart business, intelligent agents, intelligent systems, intelligent systems models, and I especially emphasized their role in managing business processes, which have become highly complex systems that are in a permanent change to meet the requirements of timely decision making. The purpose of this paper is to prove that there is no business without using the integration Business Process Management, Web Services and intelligent agents.business intelligence, intelligent agents, intelligent systems, management, enterprise, web services

    Semantic Web Services can be seen as remote Problem Solving Methods offered via the Web through platform and language independent interfaces. They can be seamlessly integrated to achieve more complex functionality by composing pre-existing software components. Despite technical advantages surrounding Semantic Web Services technologies, their perspective overlooks the commercial aspects of services in the real – non-IT – world, and is therefore incomplete and limiting. Real-world services – business activities such as insurances, medical services, ADSL etc – have nowadays an increasing social and economic importance. Important trends are the bundling of services and a growing customer-need orientation. Thus, there is a need for a computational background for describing real-world services and applying knowledge-based technologies for reasoning about them: configuring composite services and analysing them from a business perspective. We have developed ontologies and software tools to fill this gap, and applied them to industrial case studies. We present here a case study from the music industry, going from the analysis of a new business scenario to the development of an application called Xena that coordinates IT infrastructures in order to provide a profitable service that reflects major business principles. As opposed to currently proposed solutions in the Semantic Web Services community, our system is an automated implementation of a real-world service where important business decisions can be traced back

    ICCASA - A Context-Based Security Framework for Cloud Services

    Get PDF
    This paper discusses the use of Aspect-Oriented Programming (AOP) as an efficient way to handle cloud computing frontend security concerns. Without AOP, the necessary security code would be mixed with the business logic that the cloud service provider implements. This makes the maintenance of both code and business logic tedious and prone to errors. The proposed aspect-oriented approach in this paper is built upon a Web services frontend to the cloud service. Three types of context are taken into account when tuning the aspects (security services). The contexts contain various details on the environment of the Cloud and the Web services, which permit activating the necessary aspects in response to these details. A set of experiments validating this approach, are also reported in this paper
