Résumé:
Communication between end-users and spatial databases raises important
and specific issues. Unlike classical systems, it requires strong
cooperation between two major tools: spatial query language and
graphical interface. This paper addresses the problem
of building an interactive querying system for spatial databases
with an open architecture. We focus
on the following issues:
(i) design of a database-independent Graphical User Interface
(GUI) providing
query expression support and advanced user-database interaction
functionnalities
(ii) software
architecture for dealing with exchanges
between the database logical representation and a graphical representation
at the interface level (iii) implementation of spatial
data and functionnalities within a DBMS without requiring
changes in the logical data model or query language syntax.
We present a prototype coupling
the O$_{2}$ DBMS, its query language O$_{2}$Sql,
and C++/X-Window-based toolkits as graphical components for
the interface implementation.
