Abstract: Object Query Language (OQL) has been an important research issue in OODBMS.This paper sum-marizes the fundamental features and the design methodology of OQL.Based on the Strawman model.several OQLs are compared and the relevant problems are commented on.A Knowledge Object Query Language frame-work for our KOBS system is introduced.
