초록

주기억장치 데이터베이스 시스템(MMDBMS)은 디스크가 아닌 주기억장치를 주요 저장 매체로 사용하므로, 고성능이 요구되는 데이터베이스 응용을 효과적으로 지원한다. 최근, 인터넷을 중심으로 고속 데이터 처리와 함께, 보다 향상된 데이터 표현력과 보다 엄격한 데이터 일관성 보장에 대한 요구가 증대되고 있다. MMDBMS에서는 모든 데이터가 주기억장치에 상주하기 때문에, 성능에 대한 오버헤드 없이 그러한 요구를 만족시킬 수 있는 방법을 제공할 수 있다. 이들은 구체적으로 데이터를 처리하기 위한 연산과 참조 무결성과 같은 제약들로 이루어진다. 이들로 구성된 데이터 모델은 MMDBMS에서 데이터베이스의 표현력을 측정하는 중요한 컴포넌트이다. 본 논문에서는 통신 서비스의 제공에 필요한 요구들과 이를 지원하는 데이터 모델에 대해 설명한다. 다루는 주요 이슈들은 1) 포인터를 사용한 테이블간의 관계성 정의, 2) 관계성에 의한 데이터들의 항해, 3) 포인터 연산에 대한 참조 무결성 지원, 4) 죠인시 균일한 처리 시간 보장, 5) 객체지향 특성 지원, 6) 다중 테이블간 인덱스의 공유 등이다. 본 논문에서는 복잡한 응용 환경에서 이러한 이슈들을 지원할 수 있도록 설계한 데이터 모델에 대해 설명한다.

The main memory database systems (MMDBMS) efficiently supports various database applications that require high performance since it employs main memory rather than disk as a primary storage. Recently, it has been increased needs that have the fast data processing as well as the efficient modeling of application requiring for a complicated structure, and conformity to applications that need the strict dta consistency. In MMDBMS, because all the data is located in the main memory, it can support the usable expression methods of data satisfying their needs without performance overhead. The method has the operation to manipulate the data and the constraint such as referential integrity in more detail. The data model consists of this methods is an essential component to decide the expression power of DBMS. In this paper, we discuss about various requests to provide the communication services and propose the data model that support it. The mainly discussed issues are 1) definition of the relationship between tables using the pointer, 2) navigation of the data using the relationship, 3) support of the referential integrity for pointer, 4) support of the uniform processing time for the join, 5) support of the object-oriented concepts, and 6) sharing of an index on multi-tables. We discuss the pointer-based data model that designed to include these issues to efficiently support complication environments.
