The Graphical Object Query Language (GOQL) is a query language that complies with the ODMG standard and which runs on top of the O2 DBMS. The GOQL User Interface comprises the User's View (UV) and the Folders Window (FW). The UV is a graphical representation of an ODMG database scheme, which hides from end-users most of the perplexing details of the object-oriented database model. The FW is a condensed version of the UV that serves as canvas upon which ad-hoc queries are constructed. The paper addresses principles behind the design of User Interfaces and discusses features and characteristics of the GOQL User Interface.
