Abstract: 본 발명은 객체지향 DBMS의 객체지향 커널에서 경로 인덱스를 관리하는 방법에 관한 것으로서, 종래에는 객체지향 DBMS에서 경로 인덱스를 지원하는 것이 있긴 하지만 관리방법이 등록된 것이 없으므로 상기 문제점을 해결하기 위해 본 발명은 객체지향 DBMS에서 경로 표현식을 사용한 질의에 대한 데이터 베이스 검색을 빠르게 하는 다중인덱스를 지원함에 있어, 다중 인덱스 관리에 필요한 정보를 카탈로그를 이용하여 관리할 때 질의 시의 검색 속도를 향상시키고, 중복 인덱스 생성을 방지할 수 있는 카탈로그 구조와 관리방법을 제언함으로써, 여러 경로 인덱스 생성 시에 동일한 어트리뷰트에 대한 중복 인덱스 생성을 방지할 수 있다.
