Abstract: A system for interactive, dynamic, three-dimensional presentation of a database's structure allows the user to efficiently navigate through the database to examine the desired information. The present system graphically depicts the organization of the information base as "molecules" consisting of structured parallel "threads" of connected nodes each encompassing a specific aspect of the overall database. Within a given thread, the component nodes, which share a commonality of subject, are arranged in a natural, linear progression which reflects the organizational structure of the information subject represented by the thread, thereby providing the user with a visual guide suggesting the appropriate sequence of nodes to be viewed.
