SOAP is a protocol used for information exchange in distributed computing environment and defines mechanisms for message transferring between distributed system and remote procedure cai]/response process. This SOAP is able to be used independently on operating systems and program languages because it is a protocol using text-based XML. Therefore ebXML that is a standard for I-Commerce adopts SOAP for message exchange. In this paper, we developed XML Hub System based on SOAP By this in Hub System we can more easily exchange messages for B2B. Accordingly we can manage and integrate a lots of business partners.

With the recent development of the ubiquitous computing technology, there are increasing interest and research in technologies such as sensors and RFID related to information recognition and location positioning in various ubiquitous fields. Especially, RTLS(Real-Time Locating Services) dealing with spatio-temporal data is emerging as a promising technology. For these reasons, the ISO/IEC published the RTLS standard specification for compatibility and interoperability in RTLS. Therefore, in this paper, we designed and implemented Spatio-temporal Query Processing Systems for efficiently managing and searching the incoming Spatio-temporal data stream of moving objects. Spatio-temporal Query Processing Systems's spatio-temporal middleware maintains interoperability among heterogeneous devices and guarantees data integrity in query processing through real time processing of unceasing spatio-temporal data streams and two way synchronization of spatio-temporal DBMSs. Web Server uses the SOAP(Simple Object Access Protocol) message between client and server for interoperability and translates client's SOAP message into CQL(Continuous Query Language) of the spatio-temporal middleware. Finally, this thesis proved the utility of the system by applying the spatio-temporal Query Processing Systems to a real-time Locating Services.

A collaboration supporting system, which enables multi-user collaboration and communication in Internet environment, is being a new indispensable tool to compete and collaborate with business peers. A collaboration supporting system in distributed environment requires scalable and open system architecture to rapidly deploy a new technology and trends. In this paper, we propose such a collaboration supporting system where communication API is using XML(Extended Markup Language)-based SOAP(Simple Object Access Protocol)protocols, which Is independent on programming language and platform. In our system, server components are developed with EJB(Enterprise Java Beans). System analysis, design, and development are based on UML(Unified Modeling Language).

An XML is widely used for web services, such as SOAP(Simple Object Access Protocol) and REST (Representational State Transfer), and also de facto standard for representing data. Since the XML parser using DOM(Document Object Model) requires a preprocessing task creating a DOM-tree, and then storing it into memory, embedded systems with limited resources typically employ a streaming XML parser without preprocessing. In this paper, we propose a new architecture for the streaming XML parser using an APSearch(Adaptive Parallel Search) on FPGA(Field Programmable Gate Array). Compared to other approaches, the proposed APSearch parser dramatically reduces overhead on the software side and achieves about 2.55 and 2.96 times improvement in the time needed for an XML parsing. Therefore, our APSearch parser is suitable for systems to speed up XML parsing.

최근 인터넷 기술의 급속한 보급과 발전은 컴퓨팅 패러다임의 변화를 촉진시키고 있다. 이러한 컴퓨팅 패러다임 변화의 중심에는 인터넷을 기반으로 네트워크화 되는 e비즈니스가 등장하였다. e비즈니스 환경에서 기업들은 다양한 거래 파트너를 관리하게 된다. 이로 인해 보다 효율적인 관리가 필요하며 자주 발생하는 거래 파트너의 변화에 신속히 대처하기 위해 이를 관장하고 처리해주는 시스템이 필요하다. 또한 거래 파트너와의 메시지 교환에 있어서 메시지 전송에 대한 요청/응답을 담하고 응답 지연과 실패에 대한 처리가 필요하다. 따라서 본 논문에서는 SOAP(Simple Object Access Protocol)을 이용한 XML Hub 시스템을 설계하여 이를 해결하고자 한다.

다양한 어플리케이션 간의 분산 객체를 사용하고자 할 때 지금까지는 DCOM/CORBA bridge를 사용하여 문제를 해결해 왔다. 그러나 이러한 분산 객체 프로토콜을 인트라넷이 아닌 인터넷에서 사용할 때는 임의로 할당받은 프로토콜을 사용하여 상호접근하게 되므로 보안상의 문제를 갖게 된다. 따라서 이러한 문제를 해결하기 위하여 방화벽을 설치한다. 하지만 여러 조건을 바탕으로 들어오는 트래픽을 블로킹함으로써 효과적인 분산 객체 프로토콜을 사용하는데 또한 문제를 갖게 된다. 본 논문에서는 기존의 인터넷 인프라스트럭처에 그대로 사용할 수 있고, 이기종 환경에 관계없이 메시지를 교환할 수 있는 SOAP(Simple Object Access Protocol)에 대한 연구와 그 적용 사례로 인터넷 서점을 구현하여 제시하였다.

In this paper, we propose a design methodology of RESTful SOAP-based web services which try to solve extensibility problem of SOAP-based Web service by adopting REST concept into SOAP. And, we apply the proposed RESTful SOAP-based web services design methodology in constructing slip data processing web services, compare it with simple SOAP-based slip data web services, and try to propose a model for building Web Services in the future. REST is a model about architecture type of web distributed computing , the biggest distributed application in the world. In REST, identification of resources are made by URI, states(resources) are represented by document described by XML and transferred through HTTP our proposed RESTful SOAP-based web services are expected to contribute to constructing useful world wide web services which are essential in building E-Commerce society.

A Web Service is an URL addressable set of functionality that is exposed over a network to serve as a building Hock for creating distributed applications. SOAP is a protocol that Web Service consumers often use, when they request and response to a Web Service, and it is a lightweight, XML-based protocol over HTTP for exchange to information in decentralized, distributed environments. A Web Service is very useful forimplementing common functions in especially a large size business area, because it is invoked by a protocol like HTTP or SOAP that we easily use, and by an XML-based data format In this paper, we implement Web Services that process dip data by computers in enterprise accounts in order to enhance the transparency and productivity of enterprises. we analyse the structure of slip data, design dip database, implement stored procedures for manipulating data of slip database, and make thorn controlled by Web Services. The result of this paper will contribute to the standardization and activation of accounting process systems for e-business area.

Web services are key applications in business­to-business, business-to-customer, and enterprise applications integration solutions. As the mobile internet becomes one of the main methods for information delivery, mobile Web Services are regarded as a critical aspect of e-business architecture. In this paper, we proposed a mobile Web Services middleware that converts conventional internet services into mobile Web services. We implemented a WSDL (Web Service Description Language) builder that converts HTML/XML into WSDL and a SAOP (Simple Object Access Protocol) message processor that performs SOAP message handling, chain and handling of server requests. The former minimizes the overhead cost of rebuilding mobile Web Services and enables seamless services between wired and wireless internet services. The latter enhances SOAP processing performance by eliminating the Servlet container (Tomcat), a required component of typical Web services implementation. Our main contributions are to overcome the latency problem of current Web Services and to provide an easy mobile Web service implementation. Our system can completely support standard Web Services protocol, minimizing communication overhead, message processing time, and server overload. Finally we compare our empirical results with those of typical Web Services.
