Abstract :
A global information system (GIS) is an umbrella system that presents a global schema of the data available in its underlying, component, autonomous information systems and provides its users with the capability to ask queries of the global scheme and to receive integrated answers. The major research areas confronting GIS developers are examined. They are: development of global schema; query processing and data access; security; recovery from failure; integration of the user workstation with the GIS; and support for multimedia objects
