Mavigator - prototype

This is the Mavigator prototype, which has been developed as a part of my Ph. D. Thesis: "Usability of Visual Information Retrieval Metaphors for Object-Oriented Databases". Mavigator is an easy-to-use visual information retrieval system. The metaphors allow the naive users (computer non-professionals) to retrieve information from any data source, including relational/object-oriented databases in an easy and intuitive form.
