Specifying service-oriented system, which is a new type of Enterprise Information System, is critical with the rapid development of Web Services. For the purpose, this paper presents an approach to model ServiceOriented Architecture (SOA). We do not exclude the traditional opinions of software architecture description as the current specification approaches; on the contrary, some similar concep...

Nowadays, a major paradigm of large scale distributed processing is service-oriented computing (or SOA, Service Oriented Architecture). To improve availability and reliability of SOA based systems and applications, a Reliability Service (providing external support of web services recovery) is proposed.

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...

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...
