The paper addresses issues related to the design of a graphical query mechanism that can act as an interface to any Object-Oriented Data Base System (OODBS), in general, and the Object Model of ODMG 2.0, in particular. In the paper, a brief literature survey of related work is given, and an analysis methodology that allows the evaluation of such languages is proposed. Moreover, the User's View level of a new graphical query language, namely GOQL (Graphical Object Query Language), for ODMG 2.0 is presented. The User's View level provides a graphical schema that does not contain any of the perplexing details of an object-oriented database schema, and it also provides a foundation for a graphical interface that can supports ad-hoc queries for object-oriented database applications. Herein we illustrate, using an example, the User's View level of GOQL.
