This paper proposes a novel Web Services enhancement method, which enhances XML based e-commerce and Web Services securely and efficiently. Recently, the ratio of XML Denial of Services (XDOS) is increased significantly However, XML data is visible only at the target application site or the application layer. Thus, an efficient and secure mechanism handling XML data on the network layer to provide fast performance on the server and protect XDOS at network level is strongly required basic component. This paper presents many issues and gives useful results from the various experiments to support an implemented XAN platform.

Especially, MTO(Make-To-Order) companies take collaborative approaches with their partner companies to make low-price products and/or technologically low intensive products. The collaborative approach to manufacturing requires collaboration with partner companies for inventory review, production plan, and manufacturing to fulfill customer's orders. However, frequent changes of partnerships binder partner companies from sharing production information in effective ways since their information systems have different data architectures and platforms. Therefore, it is required flexible and standardized system integration approach fir effective information sharing. This research studies current status and problems of collaborative production system, proposes an architecture for collaborative production systems based on Web Services which is a standard information technology, and discusses expected effects and the vision of Web Services.

In this study, system of opening of archival documents and providing reference services and archives web service in China have been reviewed. Throughout laws and regulations of archives management since found the People's Republic of China, related to opening of archival documents and providing reference services are analyzed. This paper also consider the present condition of archives web service in China and web service of Beijing archives.

The Web Services Choreography Description Language (WS-CDL) is an XML-based language that describes peer-to-peer collaborations of parties by defining, from a global viewpoint, their common and complementary observable behavior; where ordered message exchanges result in accomplishing a common business goal. In this paper, we survey and analysis the functionality of the WS-CDL, and propose new language, which enhance the WS-CDL for the conversation the message between entities

Conventional command-based communication services are rapidly substituted by multimedia web-based communication services at most recent times. As the result, many valuable database and services developed by investing lots of human and material resources become to be useless. Therefore in this paper we researched the implementation methods and techniques for making the updates efficiently from the conventional command-based database services to a multimedia web-based database system that made users easily access to database and services.

Because of paradigm change to web service, numerous institutes have been suggested supporting solution about web service, and actively developed system using web service but it is hard to find out a systematic study for web service performance enhancement. Generally, there are SOAP message processing improvement and configuration optimization of server viewpoint for web service performance enhancement. Web service performance enhancement through SOAP message processing improvement have been studied related research but configuration optimization of server is hard to find out a systematic tuning model and performance criteria. In this paper, I suggested performance testing based tuning model and criteria of configuration optimization of server viewpoint. We executed practical analysis using tuning model about web service in internet. This paper show that the proposed tuning model and performance criteria is applicable to web service performance enhancement.

Web service should be to connect business between enterprise through the Internet, promotion of construction speed and decrease of development expense of service construction are possible. Also, unification with other domain is possible easily, and update or correction is easy by offering reusability and replaceability through component based development. In this paper, We suggest development process to build architecture and this to integrate consisted component efficiently to develop web service that is embodied in supplier side on service oriented architecture(SOA). The suggest architecture to integrate component that is consisted for this efficiently, and describes development process. So that component develops web service to base structure of web service because do command stratification logically function in each hierarchy define, and presents architecture based on logical hierarchy. The web services consist of Facade and Backside component; The Facade component have web service functions. We describe process that develop to Facade component and present mailing web services as case study. It can be decrease production cost and development time. The web service based on component will improve reliability for reuseability and replaceability.

In this paper, we are to overcome the latency problem of current Web 2.0 Web Services system. To overcome the standard mobile web services implementation, a SOAP message processing system (SMSP) was proposed in which the SOAP request and response messages are directly processed without using Servlet engine. Our system can completely support standard Web Services protocol, reducing communication overhead, message processing time, and server overload.

Nowadays, with the proliferation of Web services, developer and user can implement a complex application by composing registered Web services. In this trend, the quality of service of a composite Web service is of crucial importance for today's Service Oriented Computing (SOC) environment. But the global optimization of a composite Web service satisfying given QoS is classified to NP-hard problem. To solve this problem, we propose K-way Super node approach and show the effect of it from experimental results.
