Service-Oriented Architecture (SOA) is a conceptual architecture that was proposed for supporting service-oriented computing. To obtain a successful design and development of service-oriented software, an architectural view model to represent and document various aspects of service-oriented software based on the SOA conceptual template is required. Various architectural view models have been proposed...
Location based services (LBS) are expected to play crucial role in future of e-commerce. Although, LBS consider service provision on the basis of location, but don't take into consideration time aspect and user's interests. We propose incorporation of time-awareness and demand-oriented contexts along with location to develop idea of community pervasive services (CPS).To identify appropriate service...
The heterogeneity, distribution and dynamicity of web services hamper WSRF (Web service resource framework) of grid to exert its excellences in resource integrations. In this paper, we propose our SOV (service orient virtualization) model for medical image grid (MedImGrid), which creates a virtual middle layer for grid to simplify the transformation from users' business aims to executable web-service...
As a practical method to simplify construction of distributed systems, Domain-Specific Modeling raises the level of abstraction beyond programming by specifying the solution directly using visual models to express domain concepts. This paper gives a visual metamodeling language which is suitable for specific domain modeling, namely XMML. It supports development and design of Domain-Specific Modeling...
At present, most of Web applications have multi-tier architectures. The Web application contains many components, which makes it become component-based Web application. This paper focuses on this kind of Web applications and constructs three dependency graphs based on structure relations and message call relations. Then we improve the path-based integration testing method, propose an extended MM-path...
Access control is important for protecting the information integrities in WfMS's. Compared to conventional access control models such as discretionary, mandatory, and role-based access control models, an access-control model based on both tasks and roles meets more requirements for modern enterprise environments. However, there are no discussions on delegation mechanisms for such a model. In this...
In this paper a new proactive customer relationship management system (CRM), BlueCRM, is proposed. The proposed system employs Bluetooth as an automatic identification token in addition to its common use as a communication channel. The system offers a low-cost proactive CRM system which is the future trend of such systems. The implementation of the prototype system comprises two sides: a database...
