The fundamental technology to the b2b e-commerce framework is Registry. Although Registries have developed, it is yet difficult to apply in actual e-business . That is, the e-business information was stored in physically and/or logically distributed and heterogeneous Registries. And Registry uses the keyword-based search to discovery the information stored. But, the keyword-based search technology can't provide the discovery the business information necessary for parties and trading partners. As spreading the understand of this problem, it requires the technologies for the integration of distributed and various Registries and the systematic definition and intelligent discovery of the e-business information. In this paper we propose the architecture of intelligent and integrated e-business registry system for solving these problems . This system composed of the Registry Integration Query Manager for integrating various registries and the Intelligent Registry Agent providing the systematic organization and discovery of e-business information.

Recently many corporations are introducing web services which supports mutual smooth information exchange without depending on platform or programming language and new distributed computing environment based on U standard technology and internet standard protocol such as HTTP. However they are suffering difficulty in interoperability because of the problem of version inconsistency of standards supported by platforms that each vender offers. To solve these interoperability problem, although WS-I is progressing a consecutive standardization work by method of that offer Basic Profile and Usage Scenario, it is in the state that the domestic research connected with this is not sufficient yet. Accordingly, this treatise constructed interoperability Test framework by developing web services on the basis of different platform from books information retrieval services that can easily be come with and simulated and verified the interoperability by applying WS-I Basic Profile.

Web service is a standardized software technology which enables interoperability for various applications regardless of operating systems and programing languages through public networks such as the internet and by web service standards. It is distributing computer services that enable a web environment by discovering and providing necessary services. However, there are drawbacks when selecting services for new web environments because current various search methods are based on performance of those services. Even when the performance of the service is improved by selecting web services based on either the service performance or when the new services are discovered, lack of resources causes the web services to get pushed back from the current service list. Therefore, in order to resolve resource allocation issues when selecting web services, this study offers the suitable services for the clients by applying improved services based on scalable information and by applying the information obtained by the clients when requested.

Peer-to-peer systems (P2P) are rapidly growing in importance on the Internet environment, quickly extending the range of their usage. However, peer-to-peer systems have not been widely applied in electronic commerce because they have not been established as an appropriate business model. Therefore, we firstly review the previous research relevant to peer-to-peer systems, and then analyze the business models for P2P systems presented by previous researchers. Furthermore, this study categorizes major issues in terms of the technical and business model aspects. On the basis of these reviews, we develop P2P electronic commerce systems based on the file sharing method between users, focusing on user interface friendliness. A developed P2P electronic commerce systems are programmed by using the C# based on the Microsoft.net solution. A database is implemented using the MSSQL2000. A main application technology is designed that P2P electronic commerce systems make it possible. for user to extend into BtoB Solution by using WSDL (Web Services Description Language), UDDI (Universal Description, Discovery, and Integration) and the XML that is a document for users. User interface is made as form of Internet messenger for a user's convenience and is possible to develop into a commodity transaction system based on XML. In this study, it is possible for the P2P electronic commerce system to have extended application to fields such as Internet shopping mall and property transaction in a nonprofit organization, a public institution and a large scale nonprofit institution that have a similar structure as compared with a structure of a nonprofit educational institution.

Service-Oriented Architecture(SOA) is improving rapidly in IT Environment. Enterprise companies interest in implementation infrastructure based on SOA to adapt quick changes of large and complex distributed environment. SOA is a component model that inter-relates the different functional units of an application, called services, through interfaces and contacts between theses services. In this paper, we studied the concept of the relationship between SOA and standard web service core and therefore, we model the web service based on SOA. We implemented the application and business service architecture using web service that include the XML and SOAP. We confirmed that how the each SOA characters like interoperability, reusability, scalability and flexible business process adapted to web service and present a web service modeling that is maintained the neutrality using loose service coupling through the method of service model process and web service architecture designing methodology based on SOA.

Recently, the rapid development of biotechnology brings the explosion of biological data and biological data host. Moreover, these data are highly distributed and heterogeneous, reflecting the distribution and heterogeneity of the Molecular Biology research community. As a consequence, the integration and interoperability of molecular biology databases are issue of considerable importance. But, up to now, most of the integrated systems such as link based system, data warehouse based system have many problems which are keeping the data up to date when the schema and data of the data source are changed. For this reason, the integrated system using web service technology that allow biological data to be fully exploited have been proposed. In this paper, we built the integrated system if the bio sequence information bated on the web service technology. The developed system allows users to get data with many format such as BSML, GenBank, Fasta to traverse disparate data resources. Also, it has better retrieval performance because the retrieval modules of the external database proceed in parallel.

과거 1990년대에 인터넷 이용이 전 세계로 확산되면서 World Wide Web를 이용하여 다양한 웹 서비스 기술의 구현 및 유통은 현재에도 개발되고 있다. 일반적으로 오늘날의 서비스는 XML 및 인터넷을 통하여 웹 서비스로 구현한 응용프로그램간의 연동을 가능하게 하는 기반기술이다. 이는 단순 객체 접근 프로토콜(SOAP), 웹 서비스 기술 언어(WSDL), 전역 비즈니스 레지스트리(UDDI) 등의 표준 기술을 사용하여 네트워크에 연결된 다른 컴퓨터 간의 분산 컴퓨팅을 지원하는 소프트웨어 및 기술이다. 이러한 웹 서비스의 발전으로 웹 서비스의 성능이 웹 서비스 제공자의 성패를 좌우하게 되고, 제공하고 있는 웹 서비스에 대한 검증이 필요하게 되었다. 웹 서비스에 대한 검증은 미국 Bloor NA(Bloor Research-North America)에서 웹 서비스 아키텍처의 단점을 발표하여 서비스의 품질과 신뢰성 및 개선점에 대하여 제시되어 활발한 연구가 진행 중에 있다. 그러나 사용자 관점에서 웹 서비스의 성능을 측정하고, 단순한 서비스 제공자의 서비스 검증 목적만이 아닌 서비스 제공자의 성능을 서비스 사용자에게 제공하는 검증 방법에 관한 연구가 많지 않은 실정이다. 하천공간정보에 대하여 웹 서비스 방식 중 통신 프로토콜인 HTTP 등을 이용한 인터넷상의 메시지 교환을 가능하게 하는 통신 프로토콜인 SOAP 및 WWW와 같은 분산 하이퍼미디어 시스템을 위한 소프트웨어 아키텍처의 한 형식인 REST(Representational State Transfer)를 실행하여 이에 따른 검증 프로세스를 수립하였다. 하천공간정보 웹 서비스에 대한 테스트 시나리오는 응답시간, 임계성능, 이용가능성, 신뢰성 및 접근성에 대하여 검증하며 하나 이상의 웹 서비스들 간의 호환성 표준의 준수 여부와 상호 운용 가능 여부를 테스트 하는 상호운용성 테스트, 신뢰성 메시징 및 분산 환경에서의 트랜잭션 처리 성능을 검증하는 웹 서비스 프로세스 품질 테스트를 실시하는 방안을 도출하고자 한다.
