초록
XML은 그 스키마가 비정규적이고 불완전한 특성을 가지고 있는 반구조적(semistructured) 데이터로써 인터넷 상의 데이터를 교환하기 위한 사실상의 표준이 되고 있다. 따라서 이러한 데이터를 효율적으로 다루기 위해서는 어떠한 저장장치에 어떠한 방식으로 저장하느냐가 중요한 요인이 된다. 본 연구에서는 기존의 객체-관계형 데이터베이스의 장점을 활용하면서도 DTD에 상관없이 XML 질의 언어에서 요구하는 다양한 질의 종류를 지원할 수 있는 저장 기법을 개발하였다. 이 기법은 XML 데이터 모델의 비정규적인 특성 때문에 발생할 수 있는 오버헤드를 최소화 시키고 현존하는 데이터와 자연스럽게 연계할 수 있다.
Abstract
XML is becoming the de facto standard for data exchange over the Internet as a semistructured data which properties are irregular and incomplete. Therefore, to handle these data efficiently, what we use storage devices and storage techniques are primary factors. In this paper, we developed storage techniques, which take the virtues of an object-relational database and support various query types needed for XML query languages without regard to the DTD. The techniques are capable of connecting naturally with conventional data and reducing overheads caused by the characteristics of an XML data model.
