Service-Oriented architectures and Service-Oriented Computing are the most recent approaches aiming at facilitating the design and development of applications on distributed systems. The primary goal of this paper is to investigate how the construction of mobile services can benefit from the Service-Oriented paradigm. The paper provides an elucidation of the ServiceOriented architecture. A gene...

Leveraging service oriented programming paradigm would significantly affect the way people build software systems. However, to achieve this goal a solid software design methodology should be grounded on proper mathematical foundations, specific service-oriented principles, concepts and patterns. This paper contributes to the above goal proposing a lightweight, but complete, mathematical framewo...

Information and Communication Technology (ICT) has helped to drive increasingly intense global competition. In turn, this intensity increases the need for flexibility and rapid changeability in ICT to support strategies that depend on organisational agility. We report a comparative, cross-cultural case study of the implementation of Service-Oriented Architectures (SOA) at a Scandinavian bank an...

This paper presents the implementation, using a Service Oriented Architecture, of an approach for dynamic flexibility and evolution in workflows through the support of flexible work practices, based not on proprietary frameworks, but on accepted ideas of how people actually work. A set of principles have been derived from a sound theoretical base and applied to the development of worklets, an e...

Although service-oriented architecture (SOA) is supposed to increase external integration capabilities, it is mostly applied within company boundaries. How companies should apply SOA to improve their inter-organizational relationships is not, as yet, well understood. Although there are several examples of service-oriented concepts in the B2B context, there has been little research in which the ...

Whereas the research in service-oriented architecture (SOA) in general is well-past the early phase, the research in the area of architectural or quality metrics for SOA is still in the early stages. A number of formal models for SOA have been proposed in the literature, and many metrics have been derived from them. This paper serves to project that such a recurrence of formal-model-proposals i...

This case describes major management and technology issues which arise when designing advanced service-oriented architectures in distributed networked environments used for e-learning. The organization at hand uses a mixed funding model and is preparing for a large expansion of its services and capacity. This case takes place after the initiation of a project and during the design phase where s...

The concept of Service-oriented Architecture (SOA) is becoming increasingly important not only in research, but also in practice. SOA has emerged as a major topic, especially in regards to the banking industry as it is one of the cutting-edge industries concerning service-orientation. SOA implementation in the German banking industry varies, with some still in the adoption phase and others alre...
