In order to make the test questions library system between data integration to realize the information sharing and interaction, this paper puts forward to service oriented SOA based architecture, enterprise service bus ESB message bus, constructs the test model, and the existing questions of the Web services package, hierarchical design of open test questions library system framework.
JavaScript has empowered users of Web applications. Using tools like Greasemonkey they can customize the application according to their specific needs through the injection of user scripts. The implementation approach, however, usually involves either extensions in the browser or client side proxies which go against the very nature of a Web application. The reason is that the customized application...
The advance in web services (WS) and service oriented architecture (SOA) applications has led to the development of new types of systems in which different heterogeneous components and platforms can connect and collaborate to solve a business problem. This advancement adds a new level of abstraction to the existing stack of technologies and development methodologies, but it adds also new challenges...
In this paper, taking GIS desktop software as a starting point, the overall framework of the GIS smart client based on SOA (Service-oriented architecture) is propounded. The GIS smart client is loosely coupled, extensible, easy to realize modularization and easy for maintenance. Existing as a component container, on the premise of with function to manage geo-spatial data to a certain extent, the GIS...
In the design of PKI certificate server, the application Held, deployment scope and consumer requirements are often considered synthetically in order to select a compatible structure pattern. At the same time, to support future technology development and possible change in system requirements well, the certificate server structure needs have some good characteristics like flexibility and extensibility...
In an age dominated by information, information quality (IQ) is one of the most important factors to consider for obtaining competitive advantages. The general approach to the study of IQ has offered numerous management approaches, IQ frameworks and list of IQ criteria. There are many IQ measures proposed for several application domains; however organizations still are challenged to apply IQ frameworks...
This paper presents a reference framework for enterprise application that use SOA architectural style. Firstly, we review the characteristic of enterprise information systems and the evolution of IT technologies. So we can conclude that using SOA approach is inevitable. Then this paper summarizes the main concept, ideas and applicable areas of SOA. We detail to discuss the classical enterprise application...
The avian flu grid is a virtual organization dedicated to the discovery of novel inhibitors for the pandemic avian flu threat, leveraging grid technologies and computational resources provided by PRAGMA and its partners. In this context it is essential to adopt tools which increase the productivity of the computational scientists without advanced training on grid technologies. To reduce the learning...
In this paper, we describe a service oriented architecture and Grid abstraction framework that allows us to access Grids through JavaScript. Obviously, such a framework integrates well with other Web 2.0 technologies. The framework consists of two parts. A client Application Programming Interface (API) to access the Grid via JavaScript and a mediator service and API through which the Grid access is...
Collaboration on the storage, processing and visualisation of medical data via the Internet is a considerable challenge and one that is growing in importance due to the escalating interest in the Virtual Physiological Human. Investigations into possible approaches for distributed, realtime visualisation are important in this context. This paper presents a Web Services approach to distributed visualisation...
