Object Relational Mapping 用後感
by calendarw on Mar.17, 2008, under architecture
自從轉左用 ORM 既 NHibernate, 以及公司某 Project 用左 Hibernate 之後, Overall 感覺都係慢既問題, Load 500 個 record 可能要成分鐘. 不過, 經我網上搵過既意見, 有部份人讚成用 ORM, 因為除左可以提升 program 既 simplicity 之外, man hour 係 develop 同 maintain 傳統 program 既時間同金錢, 應該遠比用 ORM Tool 既速度慢而買既 hardware cost 高, 所以如果要比較傳統既 SQL 方法同 ORM 黎講, 應該係後者會比較好.
