ABSTRACT:
A data processing system for storing and managing at least one shared document in a storage unit, includes a memory unit for storing first information that indicates update levels comparable to frequencies of access to shared documents in one-to-one correspondence with users, and a control unit for controlling access to the memory and storage and management of the shared documents. The control unit includes a unit that when a first user accesses any of the shared documents so as to update it, retrieves a latest update level of the shared document accessed from the first information and determines on the basis of the result of retrieval whether there is a second user who has accessed the shared document before the first user, and a unit that when the result of determination reveals that there is a second user, notifies the second user of the fact that the shared document has been updated by the first user. This configuration enables users to acquire latest correct information concerning shared documents all the time, and eventually improves the users' convenience in utilizing the shared documents.
