We make use of the idle servers to set up a provincial tax Grid based on open Grid service architecture （OGSA）. We put forward practical methods to integrate databases, to define and create basic modular Grid services and apply agent to manage Grid services. This technical innovation scheme is of a service-oriented architecture （SOA） and succeeds in averting resources waste. Tests proved that it greatly improves the quality of tax services.展开更多

The architect can instead achieve reliability by properly planning the workflow architecture. To this end he must be able to evaluate and compare the reliability of multiple architectural solutions. In this paper we present a useful tool which allows to conduct reliability analysis on planned workflows, as well as to compare the reliability of alternative solutions in a what-if analysis. The tool is implemented as a plug-in for the widely adopted Active BPEL Designer and exploits the concept of reliability pattern to evaluate the reliability formula of the workflow. The effectiveness of the approach and the operation of the tool are demonstrated with respect to a case study of a business security infrastructure realized by orchestrating simple security services.展开更多

The Geo-position of the user’s mobile device is utilized to produce location information in shopping application (SAGO). The flow of the application is that user searches a product, and then SAGO identifies the location and searches the product on the closest electronic local stores. The idea is to get the prices from each local store with in stock information and smartly listed product list. With the proposed smart filtering algorithm, mobile shopping application achieves precise and minimum error based on searching and listing results.展开更多

文摘Many high performance database servers are becoming idle with the tax data being integrated to country tax data centers. We make use of the idle servers to set up a provincial tax Grid based on open Grid service architecture （OGSA）. We put forward practical methods to integrate databases, to define and create basic modular Grid services and apply agent to manage Grid services. This technical innovation scheme is of a service-oriented architecture （SOA） and succeeds in averting resources waste. Tests proved that it greatly improves the quality of tax services.
