1. XOne data replica system is a client/server system. The central DB is managed by one or several apps that are part of the replica server. The process may be done without the relationships among the records on each copy of DataBase losing coherence. The data replica system, also, lets you to connect other copies from the central DB without selectivity. AUTOMATICALLY COPY OF DATA ON REAL TIME WITH OR WITHOUT COVERAGE

4. To deliver geographycally the data transmission, it is possible to distribute the replica server in several star-shapes nodes. That way the devices of any zone may be connected to a machine which centralizes the upload process to the central by using a more powerful link. The selectivity of the clients is executed on their own server and do not at the central one. With this mechanism, also, is possible to keep sending data when the central node links will fail.

5. The replica server is responsible for preparing the data in order the clients may receive it. It accepts the data sending from the clients and places them at the central. It makes the following tasks: SUPPORTING SEVERAL DB AT THE SAME TIME ACCEPTING CLIENTS REQUESTS. MANAGING THE CLIENTS SELECTIVITY. PROCESSING THE DATA SENT BY THE CLIENTS TO BE INSERTED INTO THE DB.

7. That information may be integrated with the client system, or processed from an XOne app. THE MAIN GOAL OF THE REPLICA CLIENT IS SENDING TO THE MAIN SERVER THE DATA OR THE FILES GENERATED BY THE MOBILITY USERS. The DB MOTORS the most used in the clients are:
