With the development of educational information, the major concerns of the university are how to manage the current dispersed information unitedly and how to realize seamless share between information systems. This paper studies using web services to implement service-oriented architecture, puts forward data share model frame based on web service and XML technology, introduces the achievements of...
The loosely-coupled and dynamic nature of web services architectures has many benefits, but also leads to an increased vulnerability to denial of service attacks. While many papers have surveyed and described these vulnerabilities, they are often theoretical and lack experimental data to validate them, and assume an obsolete state of web services technologies. This paper describes experiments involving...
By SOA (service-oriented architecture) a summary and analysis of basic theory, proposed SOA technology in military command automation system, and information systems to SOA integration in the armed forces as an example of in-depth discussions.
Service-Oriented Architecture (SOA) is a new software architecture. This paper introduces relevant theory of SOA and Web Service as one of the measures to achieve SOA, and presents an integrated framework based on web services. Furthermore, aims at the problems aroused in daily computer facilities maintenance that the University Modern Education Technology Center faces, the paper carries out analysis...
Service-oriented Architecture (SOA) is increasingly relevant across several domains of application by promising systems openness and unification over a common design and communication paradigm. At device level, the application of SOA is carried, on one hand, by Devices Profile for Web Services (DPWS) and complementary web-based specifications oriented towards resource management, and, on the other...
SOA is a new kind of architecture design for system development. It can solve heterogeneous problem by decomposing software services module and integrating service module. Traditional logistics information system has poor scalability and reusability, it is easy to form information islands. E-business logistics information system based SOA provide an ideal framework for design and implementation of...
SOAP Web services create high network traffic because of its generated large XML messages resulting in poor network performance. Therefore, enhancing the performance of Web services by compressing SOAP messages is considered to be an important issue. Compression ratios achieved by most of the existing techniques and tools are not high enough, and even a tiny improvement could save tremendous amount...
In a Sensor Web environment, sensors are heterogeneous. The Sensor planning service offers a standardized interface for the control of sensors and simulations. But some complex sensors like satellite need midterm or long-term action to response a given task, so, adding asynchronous support in SPS is necessary. The workflow description language can chain asynchronous web service together while it has...
The shop-level information integrated system is the glue of system integration between enterprise upper management systems and the underlying process control systems, the basic of executing enterprises' agile manufacture strategy. The field management and shop information integration are given more and more attention by enterprises, the methods and technologies of traditional shop management can't...
Previous work on addressing the problems of scalability and limited autonomy of data sources arising from the semantic heterogeneity of peer schema has proposed a layered model/approach of ontology integration consisting of peer and coalition ontology and the mapping between them. In particular, the integration model for achieving semantic interoperability in Data and Knowledge Systems (DAKS) is accompanied...
In this paper, are presented some possibilities for application of an algebraic method which handles XML hierarchical data structures and makes faster the XML search mechanism. The article briefly presents the concepts of Web Services, Service-Oriented Architecture and other modern software paradigms for organization of the processes over internet. The accelerating techniques for XML navigation through...
Average information workers spend most of their time for searching, analyzing, reformatting and consolidating information. The recent advent of service-oriented architectures (SOA) built on Web services is a first attempt to streamline respectively automate those tasks in order to increase productivity. SOAP-based services work well within a company and are thus mainly used to for the integration...
While web services greatly reduce the cost and complexity of integrating systems; they also introduce a number of additional challenges for testing because web services require standards, API, communication protocols and architecture that are not fully supported by traditional software testing methods and tools. In this paper, we discuss a software framework for providing a variety of test inputs...
Internet-based E-government has become a new work model of government departments. But due to heterogeneous and autonomous between different business systems, there are barriers in E-government systems when they are interoperating. To eliminate information silos, building a unified information-sharing platform is a necessary choice for the work of the government's information. This paper studies service-oriented...
Power marketing system plays an important role in customer service marketing management system, because the system involves data sharing and information application concurrently of central departments in power enterprise. It is very difficult for power marketing system to implement information sharing across power enterprise, but creating an information integrated platform to achieve information integration...
As the internet developing, web-based applications are increasingly popular in service-oriented architecture. Web service has XML support, which is the most suitable technology to achieve service-oriented architecture. Web service is essentially an interface which enables the isolations between different sites to communicate with each other. In this paper, based on .NET platform for web service and...
A large number of enterprises are turning to service-oriented architecture (SOA) for designing, using and managing their information technology (IT) systems. SOAP-based web services are the most commonly found services in today's SOA implementations. This paper reviews different possible classes of vulnerabilities in web services and investigates the advantages and shortcomings of available solutions...
Extending the applications of SOA (Service-Oriented Architecture) to embedded/mobile service systems requires the asynchronous and lightweight messaging. However, conventional SOA focuses on the synchronous and heavyweight messaging such as SOAP. Furthermore, the lightweight messaging is diverse. Designing lightweight SOA, a class of SOA based on the lightweight messaging, is complicated. To accommodate...
Interoperable DEVS modeling and simulation is desirable to enhance model composability and reusability with DEVS models and non-DEVS models in different languages and platforms. The barrier to such interoperability is that DEVS simulators implement the DEVS modeling formalism in diverse programming environments. Although the DEVS formalism specifies the same abstract simulator algorithm, different...
With the rapid development of Internet technology today, B2B e-commerce quickly grows up. Enterprises only have their own business system, is unable to meet the rapidly changing business needs, which bring by corporate merger acquisition and fierce competition. Enterprises must be able to face to the market quickly, find a better approach of information systems integration, so that suppliers and partners...
