This project is aimed at the research on new methods, techniques and tools, as well as the adaptation of those already existing, in order to improve the quality of software processes and products, paying special attention to the applications based on service oriented architectures. The technologies to develop include new testing approaches and the elaboration of simulation models of both proces...

Today’s business environment pushes organizations to be adaptive and collaborative. This push drives the development of service-oriented enterprise architecture (SOEA) in support of the organization. To realise the advantages offered by SOEA, research on avoiding SOEA implementation failure is of considerable merit. In the review of literature on SOEA implementation failure, two research proble...

Services will be the economic driver for 3G mobile networks and beyond. For the provision of new services a charging architecture supporting fast and easy integration of new services on the one hand and enabling versatile tariff models on the other hand is of vital importance. In this paper we present a service-oriented charging architecture. The key idea of the architecture is the separation o...

Service oriented architecture (SOA) is gaining more momentum with the advent of network services on the Web. A programmable and machine accessible Web is the vision of many and might represent a step towards the semantic Web. This paper reflects upon existing Web services implementations and presents an abstract containment model as a basis to model Web services. A common model for Web services...

Services are the vital part of a service-oriented architecture. Their development and design are essential parts of the development and implementation of a service-oriented architecture. Thus, numerous approaches in research and practice exist that refer to different aspects of service design. These are focused on specific needs or aspects in service design. According to the literature review p...

Recovering and analysis of workflows executed in Service-Oriented Systems (SOS) can be expected to gain more and more relevance in service-oriented information technology in the not so distant future. Our work attempts to perform workflow mining in logs provided by service-oriented architectures. Firstly, we introduce the idea of Web Services Interaction Mining (WSIM) and give an overview of re...

The concept of collaborative commerce was put forward by Gartner Group in 1999, and Web Services becomes one of the best implementation technologies of collaborative commerce for that it is loose-coupled, based on open standards and etc. In this paper, based on service oriented architecture of Web Services, we construct collaborative commerce model, analyze business process integration of colla...

Service Oriented Architecture (SOA) is currently considered as one of the most advanced means to realize quickly modular and flexible applications. A key concern for flexibility in SOA is the variability. Several works on variability were conducted. However, few studies have proposed classifications on the variability in the composition of web services. In this article, we propose an original a...

Web Services and Service-Oriented Architecture in general are promising concepts to overcome difficulties such as heterogeneity, scalability, etc. In this paper we present an algebraic structure of Web Services which assist users in Web Service composition and formal description of their services. Using relation algebra, tests and iteration offer the possibility of an automatic composition of W...
