Abstract :
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
