Short Description:

This report discusses a number of issues related to visualisation. These issues include for instance visual data presentation, visual data access, query result presentation. Furthermore, a general architecture of the ICONS prototype is presented.

Investigations concerning selected tools and methods for GUI interfaces concerns selected publicly available software. The requirements for a GUI are based on visual graphical querying metaphors assumed for the ICONS project, which are the result of literature search, research and experiments. It is assumed that three basic metaphors are to be implemented. One of them concerns storing intermediate and final results of query evaluation (basket). The others concern navigation between items of information/data: extensional navigation in an explicitly presented graph of objects, and intentional navigation in an implicitly presented graph of objects representing the UML-like database schema. These metaphors along with other ideas are supposed to solve such problems as: the support for user awareness, recording visual querying results, graph layouts, graph manipulation etc.
