This thesis describes the implementation of a prototype for a P2P database management system. This implementation established a master application laid up on local database with main user interface and four sub applications: network manager, acquaintance manager, rule generating manager, query processing manager.We are interested in the creation of Peer-to-Peer (hereafter P2P) systems that consist of autonomous databases coordinated by event-condition-action (ECA) rules. Such systems could be used for the exchange of information among peers who don't need (or want) wholesale integration of their respective databases. Conversely, the hospital database may automatically get medical data on a patient who has just been admitted.This prototype has been tested with hundreds of queries among four peers. The rule processing time increases depending on the number of peer communications contained. We analyze the performance and characteristics of this prototype through a series of experiments.
