사용자에게 제공되고 있는 대부분의 시간 지리 정보 시스템은 소프트웨어 형태로 패키지화하여 제공되므로 과다한 구축비용과 재사용성의 문제점을 가지고 있다. 그리고 시간 지리 정보 시스템은 복잡하며 대용량인 특성을 가진 시공간 데이터를 처리해야만 한다. 따라서 시공간 데이터의 효율적인 관리 및 재사용성을 위해서 소프트웨어 부품화물 제공하는 컴포넌트 개발 방법론을 사용해야하며 시공간 데이터에 빠르게 접근하기 위한 인덱스 구조가 필요하다. 이 논문에서는 시공간 데이터를 효율적으로 관리하기 위하여 4차원 시공간 객체에 대한 인덱스를 컴포넌트 개발 방법론을 적용하여 설계하였다. 그리고 다차원 인덱스를 이용하는 4D 데이터 제공자를 COM 기반의 OLE DB 인터페이스를 이용하여 구현하고 성능을 평가하였다.
