ABSTRACT:
A system for synchronizing unstructured documents includes sub-nodes (110, 120, 130) and a network connecting the sub-nodes together. Each sub-node includes a database server (113, 123, 133), an FTP (file transfer protocol) server, and client computers (111, 121, 131). The database server includes a summary table (400) for storing a summary of all unstructured documents, and has the function of synchronizing with summary tables stored in other sub-nodes. The FTP server stores unstructured documents, and has the function of downloading unstructured documents from the FTP servers of other sub-nodes. Each client computer includes a client proxy. The client proxy includes a database processing module for generating instructions on updating, searching, and deleting data stored in the database server, a file processing module for generating instructions on downloading unstructured documents from the FTP servers of other sub-nodes, and a client processing module for receiving sync orders from users.
