Abstract

Although, a number of DBMS vendors are scrambling to extend their products to handle XML, there is a need for a lightweight, DBMS and platform-independent XML repository as well. In this paper, we describe such an XML integrated repository system, that solves the following functions : generating relational schema from XML DTDs for storage of XML documents, importing data from XML documents into relational tables, creating XML documents according to a XMLQL(XML Query Language) from data extracted from a database and synchronizing the replicated XML documents. In the XML repository systems, the efficient change detection techniques for XML documents is required to maintain the consistency of replicated XML data because the same data in the repository can be replicated between so many different XML documents. In this paper, we propose a message digest based change detection technique to maintain the consistency of replicated data between client XML documents and a XML data in XML repository systems.

비록 많은 DBMS 업체들이 XML을 지원하기 위해 기존 제품들을 확장하고 있지만 이와는 별도로 DBMS 종류와 플랫폼에 독립적인 경량의 XML 리파지토리 시스템 개발이 요구되고 있다. 본 논문에서 다음과 같은 기능들을 지원하는 XML 통합 리파지토리 시스템의 설계 및 구현에 관해 기술하였다. 구현된 XML 리파지토리 시스템은 XML DTD로부터 XML 문서 저장에 필요한 스키마 구조를 생성하고 데이터베이스 테이블에 저장한 뒤 XMLQL(XML Query Language)를 통해 자유롭게 XML 문서를 생성할 수 있으며 중복된 XML 문서들을 동기화시킨다. XML 리파지토리에는 동일한 데이터가 다양한 XML 문서에 중복될 수 있기 때문에 중복된 XML 문서들의 일관성 유지를 위한 효율적인 변경 탐지 기법이 요구된다. 논문에서는 메시지 다이제스트 기반의 변경 탐지 기법을 제안함으로써 클라이언트 XML 문서와 리파지토리 안의 XML 데이터간의 일관성을 유지하도록 하였다.
