Database synchronization and organization system and method

摘要: The present invention provides a "data centric" approach to updating databases on computer systems (516) of an intermittently connected database (15d) system. In this approach, the storage and processing complexity server are decoupled from number clients be supported, thereby, improving scalability server. Instead focusing data required by individual clients, method tracks changes subsets pertaining groups clients. Thus, need only track record these data, instead tracking for Clients download subsets, which contain relevant group, merges or deletes superfluous subsets. Since is limited set related actual overall system increased. (10), client synchronized with dividing distributed into (80ad) assigning one more each When accesses server, sends made its local updates changes. After making database, determines share in made, creates modification files (86ad) groups. they assigned.
