|Abstract:||With the improvement and the proliferation of teleinformatics, the distributed systems are widely used in the software industry. A distributed system is a system for which each component is independent and often located in a place away from the other components. In such system, components communicate with each other to exchange information, to coordinate their actions, to make group decisions, etc. However, in these systems, some problematic remain; how to represent information, how to transmit information and how to manage the update information? This study is mainly interested in these problematic of distributed systems where information is centralized on a server. For the case which interests us here, only a part of information is duplicated in the components and it may not be exact. This study is related to the way of sharing knowledge between components of such distributed system. We will more particularly detail the knowledge representation, based on conceptual graphs, as well as a method of indexing this knowledge representation. We proposed an original technique of management of the updates. This technique, based on a statistical analysis of the updates, makes it possible to perceive and maintain up to date the information between the components of the system and the server. With these techniques, we hope to decrease the use of the bandwidth as well as the temporary inconsistency of information between the components and the server.|
