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...
This paper describes the results of the FP6 project SWIM-SUIT (System Wide Information Management -- Supported by Innovative Technologies) that currently integrates a number of existing ATM (Air Traffic Management) systems on top of a newly build prototype. As SWIM-SUIT has been identified to provide relevant inputs to SESAR, the authors give an overview on the prototype architecture and major software...
Praised as of future generation technology architecture of integration, SOA (Service-Oriented Architecture) can be used to resolve the difficult problem in exchanging of information system. Foreign software providers' products of SOA are not applicable to domestic enterprises in development from the aspects of ease and cost performance. Using the latest open-source architecture, the paper analyzes...
The programmable network envisioned in the late 1990s within standardization and research for the Intelligent Network is taking another attempt to come into reality using IP-based Next Generation Networks (NGN) and Application Programming Interfaces (API) for open developer access. Adopting technical concepts of providing high-level APIs for open service access from the Internet and World Wide Web...
Testing Service Oriented Architecture applications is a challenging task due to the high dynamism, the low coupling and the low testability of services. Web services, a popular implementation of services, are usually provided as black box and using testing techniques based on implementation is limited. This paper presents an approach to support the use of the structural testing technique on web service...
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...
Migrating legacy object-oriented system functionalities to SOA environment is a important problem that frequently arises in many system maintenance and integration tasks. A service is often implemented by complex collaborations of many objects in an object-oriented system. Such complexity brings impedance mismatch between service and object. Moreover, the delocalized nature of object-oriented system,...
Large scale Service Oriented Architecture (SOA) developments are becoming increasingly reliant on registry services that manage Web Services using taxonomic attributes. At present a registry stores a Web Services interface definition and protocol bindings in WSDL, along with one or more XML schema files that define the structure of a SOAP message exchanged between Web Services operations and client...
While many research projects in the world have been addressing challenges posed by digital preservation, digital libraries in China have their own native problems that have never been addressed before. Similar problems may occur in other countries, and their memory institutions may be less prepared to handle them. Quite often, information in the native special digital objects is also unique in world...
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.
Current theories and systems do not satisfy the requirements of P2P streaming on Internet in aspects of large scale, high quality and low cost. The transmission model of overlay network is the key factor. This paper proposes Regular Structured Model for P2P streaming including overlay network theory and management mechanisms. We developed ClusterStream a high service quality streaming system based...
This paper presents a methodology for composing a SOA service chain by evaluating and selecting a service for the purpose of business result optimization. The methodology requires the business performance model for applied services to measure the value produced by services in a specific business context. Understanding the business characteristics where services are applied is a prerequisite for evaluating...
The development of web 2.0 increases the call for agile and simple Business process support. SOA (Service oriented Architecture) provides companies with a new model to build their IT applications around their business processes and combine them dynamically and flexibly with the services of partner companies. In this open and distributed context, it is required to implement an appropriate security...
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...
The commercial exchanged procedure among enterprises is complicated, and adopting information system of each other is mostly different. The circulation of each other's information and merger of the workflow are a complicated problem, for instance: trades, orders, stocks up etc., include a lot of trade files and goods information among them. Under the environment of global commercial competition, how...
Version management of WS-BPEL (Business Process Execution Language, BPEL) processes in SOA is not supported in a consistent way. Therefore, in this paper we propose specific extensions for BPEL to support versioning of processes and partner links. We introduce new activities and extends existing activities, including partner links, invoke, receive, import, and on-message activities. We propose version-related...
Although there have been many benefits of Domain-Specific Languages (DSLs) reported from both academia and industry, implementation of DSLs continue to face challenges with respect to frequent evolution of both syntax and semantics. Techniques for implementing DSLs also lack interoperable capabilities among base languages and limited tool support. Such challenges result in increasing DSL development...
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...
With the popularity of SOA, SOA policy becomes one of the core technical enablers for SOA governance and management. Different in several aspects from traditional policy for distributed system management, policy applied in SOA solutions needs to take into account various policy types and enforcement points in different layers of SOA solution stack and different phases of SOA lifecycle. As well, it...
Considering the current situation of the data on oil and gas resources in China, which is relatively multi-sourced, heterogeneous and decentralized, as well as the actual demand of OLAP, MVC model is employed as the system constructing model. Besides, ODBC and XML technology are combined to achieve dynamic mapping on database connection. Thus the National Petroleum Resource Database ETL System which...
