위상적 무결성 제약조건과 능동 규칙을 사용한 제약조건 관리 시스템 = Topological Integrity Constraints and Constraints Maintenance System using Active Rules

다국어 초록 (Multilingual Abstract)

A research area in GIS(Geographical Information System) has been so far focused on the data modeling, and on the efficient storing method, and on the indexing method of spatial objects, etc.. We can classify spatial errors as geometric errors, semantic errors and topological errors. The topological errors are of great importance in GIS data consistency. Topological errors, which are a kind of semantic errors, are based on topological relationships. Errors detected in GIS data come from the lack of cognition of topological relationships between spatial objects stored in database. Topological relationships will help finding errors and correcting them in GIS data. In this paper, we will survey several papers about spatial errors, and describe the definition process of the topological integrity constraints. We will also survey existing active DBMSS, and discuss how we can use active rules in constraints maintenance. Then, we will design and implement topological integrity maintenance system.
