As the need for more pervasive and more complex access controls grows, the challenge of ensuring the <bold> performance</bold> of access control systems is becoming apparent. Researchers have proposed several solutions to mitigate performance problems, including: adjusting the policy set; re-engineering the policy decision point (PDP); and decomposing the policies and distributing their...
A service system addresses the interactions and balances between the supplier communities and consumer communities with the help of appropriate infrastructure such as Service Oriented Architecture (SOA). This paper extends an existing service system prototype for e-business with the focus on in-memory processing of XML-based large volumes of data, information and knowledge without the I/O operations...
Through the introduction of SOA(Service Oriented Architecture), enterprises have recently had the benefit of legacy software reuse, heterogeneous environment integration, and ROI(Return On Investment) maximization. SOA consists of a service client, service provider, and service registry. Within this environment, we proposed a service with variability on the basis of a product line concept. Services...
For the key issues involved in the construction of logistics information system of flexible manufacturing enterprises (shortened as FME), this paper puts forward the corresponding solution. First of all, through the comparative analysis between the C/S and B/S, the authors hold that adopting B/S three-tier architecture is able to integrate service management and unify services to the client, thus,...
This paper presents a Capability Ontology (CapOnt) and a rule-based reasoning mechanism, which support service management within adaptable service systems. The ontology concepts comprise capability types, capability parameters and service management functions related to capabilities. Capability parameter values can be defined by constraints on other capability parameters. The service management functions...
Across-district emergency response is the mode of calling for different geographical emergency department to respond as a united system when the response area is insufficient force in tackling emergency situations. In this paper, which major in database layer and application layer, presents a scheme of emergency response transaction and information sharing system based on WebGIS and service technology...
During the last years, 3G standardization activities lead to new directions both in network and service provisioning architecture. As a result, new concepts of service portability have been defined (i.e., virtual home environment - VHE) and new topics related to security issues are gaining a significant impact. Taking into account such an input, we moved to promote the development of a new generation...
