클라이언트/서버 환경, 다양만 플랫폼지원, 다양한 어플리케이션 인터페이스 통합관점에서 소프트웨어 재사용 방법은 소프트웨어 공학의 주요 이슈가 되고 있다. 최근 호환되지 않는 어플리케이션을 통합 처리하는 방법으로 EAI(Enterprise Application Integration: 전사적 어플리케이션 통합)가 대두되고 있다 EAI는 이 기종간에 어플리케이션을 통합하는 것으로서, 필요한 정보의 통합, 관리를 제공하며, 다른 환경의 어플리케이션에서 이질적인 데이터를 사용할 수 있도록 환경을 구현 한 것이다. 이러한 어플리케이션을 통합하는데 있어서 본 논문에서는 최소한의 변경만으로 통합이 가능하고, 쉽게 적용 할 수 있도록 하기 위만 방법으로 퉁합 메시지 패싱 방법을 제시 하고자 한다. 본 논문에서는 EJB(Enterprise Java Beans), JMS(Java Messaging Service)를 이용하여 통합 메시지 어댑터를 정의하고 그 방법을 제 시 한다.

최근 부각되고 있는 기업 업무 프로세스 통합을 위해 EAI(Enterprise Application Integration) 시스템을 도입하고 있다. 하지만 아직 EAI 시스템의 품질을 보증하기 위한 테스트 방법이 제공되고 있지 않는 실정이다. 본 논문에서는 EAI의 기능을 이루는 요소별로 분리하고, 각각 분리된 기능별로 테스트를 수행하는 방법을 제시하고자 한다.

Existing application systems of enterprises can process and collect a lot of information within enterprises, but it could be difficult to share validated information with partners and other system in the process of contacting to other legacy systems required in cooperation environment. For solving these problems, EAI systems are introduced in cooperation environment so that data sharing and integration can be achieved. The integration based on EAI is not limited to particular business system but all systems of an enterprise so that standard of suitable metadata level is needed for forwarding consistently between each business of systems. Therefore this paper maintains consistency of data sharing and integrating among legacy systems in cooperative environment for proposing message exchanging based on bridge XMDR.

Recently companies are aggressively pushing ahead with integrating the systematical applications of internal and external information systems such as Data level, Application level, Process level in the company, Process level between companies. The EAI solution is generally considered as the necessary tool to integrate companies, but the appraisal standard for the EAI solution has not yet settled in Korea, so the companies have difficulty in deciding whether to adopt the EAI solution or not. Through this report, we first introduce the KRA Project as the best practice in making an application of the settled standard to evaluate and adopt the EAI solution, and then suggest that it can be adapted to companies considering applying to the EAI solution.

Recently enterprises introduce EAI systems and legacy business which already obtained for data integration among legacy systems. EAI systems in cooperative transaction environment can be expected efficient retrieval as sharing and integrating. However existing legacy systems have to introduce particular EAI solution because it is difficult to adjust standard technology to EAI due to be managed independently without considering interoperability. For solving these problems we use metadata registry using data integration. Various types, semantic specification data heterogeneity and heterogeneity of systems, however, are occurred. Therefore retrieval system based on XMDR(extended Meta-Data Registry) for data interoperability in the web environment are proposed in this paper.

Not only Enterprise Application Integration (EAI) within a company but also business-to-business integration (B2Bi) should be achieved for companies to collaborate seamlessly through the Internet. There have been great efforts in this area of EAI and B2Bi, resulting in lots of solutions in the market. However, EAI and B2Bi systems have been designed and operated in independent platforms and environments causing a serious problem of integrating EAI and B2Bi systems. In this paper we have proposed a business integration platform for connecting EAI and B2Bi systems in a uniform architecture and also coping with changes in business environments. In the integration platform proposed in this work, collaboration processes between B2B companies can be performed using Web Services technology widely considered as B2B integration platform. Especially, we have defined basic business execution elements based on a thorough analysis of various business integration standards and developed an efficient and extensible business process engine for B2B collaboration process management. A Web-based order processing system is developed for validation of our integration platform. It is expected that the level of B2B collaboration can be enhanced using the integration platform and furthermore it will contribute to more collaborative B2B commerce.

It is important to integrate an enterprise application for automating of the business profess, which is responded by a flow of market environment. There are two categories of method that integrate enterprise applications. One is Synchronous Integration, and the other is Asynchronous Integration. EAI(Enterprise Application Integration) and Web service which of the asynchronous integration is focused in the automating method of the business process. After we construct the application integration for automating of the business process, we have to concern about managing of the business transaction. Many Organizations have proposed the process method of business transaction based on 2-phase commit protocol. But this method can′t supply the phase that classify the transaction by transaction weight. In this paper, we propose an efficient method of transaction process for business transactions, which is composed by ′Classify Phase′ that classify transactions. We called this model "3-Phase Commit Method Applied by Classify Phase", we design this model to manage an resource of enterprise efficiently. The proposed method is compared by the method based on 2-Phase commit that could be a problem of management the resource of enterprise, and the advantage of this method is certified to propose the solution of that problem.

To cope with rapidly changing enterprise environment, many business entities introduce EAI, which integrates applications by installing middleware. But existing EAI has a serious problem that is to import imddleware-dependent coding method to integrate systems, using different middlewares. In this paper, we suggest middleware independent 'Workflow Management System' which efficiently integrates applications of various middleware systems with 'Duplicate EAI Adapter', 'state chart' and 'XML' technology.

A business process is classified into two processes; the private process which is implemented within an enterprise and the public process which is implemented between enterprises. The public process commonly used for B2B e-business is defined as a collaborative business process. To date, the collaborative business process has been studied in various aspects. We have categorized the research trends into two viewpoints, i.e., EAI(Enterprise Application Integration) and B2Bi (business to business Integration). In this paper, research trends in inter-organizational workflow are analyzed from the EAI point of view, and research trends in message-based business process and transactions from the B2Bi point of view.

This paper describes the design and implementation of the PKI-based EAI system which is used for delivery of sensitive personal information between business systems. For this purpose, we propose a key exchange protocol with some key process : Diffie-Hellman Schema is used to provide forward secrecy, public key-based digital signature is used for EAI Server authentication, data integrity. In addition, in order to minimize the performance impact on the overall EAI systems. The EAI server was designed simply to be used only as a gateway. This paper shows the implementation of Korea public key authentication algorithm standard and a symmetric encryption algorithm for data encryption.
