Abstract This paper describes the architecture and implementation of Graphical Navigator, a system for visualizing and querying databases. The schema of a database is represented by classes and associations between the classes. Thus, a database is viewed as a labeled graph. A graphical query notation was developed to query databases. The query notation allows formulation of recursive and predicated queries. The system facilitates incremental querying by way of workspaces. The formulation, execution and incremental querying are all done in a highly interactive and visual environment.
