.... on technologies of extensible databases that can be used to encapsulate complex access methods on non structured, spatial data objects [8,18] A second part of the efforts focused on appropriate visual interfaces and on query languages to navigate through highly non structured information sets [2,16]. A third part, which is the study area of this work, concentrated on the definition and implementation of appropriate architectures to support open, distributed geographical information systems [7,11] 3. DISTRIBUTED SYSTEMS Distributed systems involve interconnectivity and interoperability. ....
