- 요약 :Active database systems integrate active rules into a database system and they provide a uniform mechanism for advanced database features, including integrity constraint enforcement, derived data maintenance, triggers, protection, and others. Whenever a database state is changed, active rule(s) is(are) automatically triggered to guarantee consistency and integrity of data.However, because conditions in triggered rules must be evaluated to decide whether they are executed or not, and execution results of rules are stored into database, active database systems continuously access database. As a result, performance of overall database systems is degraded. Therefore, their performance depends on optimization of rules, efficient condition evaluation, the number of database access and others.To reduce frequent database access caused by consecutive trigger of rules, we propose rule buffering and its structure and show its applicable examples.
