초록

기업이 시장 환경 변화에 빠르게 대응하기 위해서는 기업 업무 프로세스의 자동화가 필요하고 이러한 자동화를 위해서는 기업 응용 체계를 통합해야 한다. 기업 응용 체계를 통합하는 방법으로는 동기적 통합(Synchronous Integration) 방식과 비동기적 통합(Asynchronous Integration) 방식이 있으며 비동기적 통합 방식으로써 EAT(Enterprise Application Integration)와 Web Service는 기업 업무 프로세스를 통합할 수 있는 방법으로써 최근 대두되고 있는 방식 중에 하나이다. 비동기적 통합(Asynchronous Integration)방식을 이용하여 기업의 응용 프로그램들을 통합한 후에는 업무 프로세스의 처리 과정인 비즈니스 트랜잭션을 자동으로 처리하기 위한 트랜잭션 관리가 필요하게 된다. 이를 위해서2PC 프로토콜(2-Phase Commit Protocol)을 근간으로 한 비즈니스 트랜잭션 처리 모델들이 제안되고 있으나 기업 자원을 효율적으로 활용할 수 있는 데는 한계가 있다. 따라서 본 논문에서는 기업의 응용 프로그램들을 통합할 수 있는 환경으로써 EAI와 Web Service와 같은 유연한 결합(Loosely Coupled)의 분산 환경에서 기업 자원을 효율적으로 관리하면서 트랜잭션을 처리하기 위한 모델을 제안한다 이 방식은 2PC 프로토콜 방식을 보완하기 위하여 Classify Phase를 추가한 3PC 프로토콜(3-Phase Commit Protocol)방식으로서 유연한 결합 환경에서 트랜잭션을 효율적으로 관리하고 트랜잭션 처리 자원을 절약할 수 있도록 한 방식이다. 본 논문에서는 기존의 분산 트랜잭션 처리방식인 2PC 프로토콜 기반의 트랜잭션 처리 모델의 문제점을 제시하고 이를 해결하기 위한 방법을 제시함으로써 제안한 모델의 성능을 확인하였다.

It is important to integrate an enterprise application for automating of the business process, 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.ion of that problem.
