【Example】

[0008] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a configuration explanatory diagram of an embodiment of a data management device according to the present invention, in which 1 is a database, 11 is a data storage device, 111 is data before editing (pre-update data), and 12 is an update date and time (update date and time). ) A data management unit having a recording unit, 121 an update unit data, 13 a data comparison unit, 2 a mail management device that manages messages as emails, and 3 a workstation (here, a workstation that executes data updates). , 31 is a data editing unit that performs processing such as updating data, 311 is edited data, 32 is a display device, 33 is a user input device such as a keyboard, and 34 is a mail editing unit (message editing unit) that edits a message as an email. ), 35 is a mail transmitting unit (message transmitting unit) that sends messages as mail to other workstations, 10 is a communication network such as a local area network (hereinafter simply referred to as a network), and 4 and 5 are other workstations. be.

The user of the workstation 3 transfers desired data to the data storage device 11 through the data management section 12.
to its own data editing section 31. The user uses the data editing section to edit the data, that is, change the data, etc., on the retrieved data. The edited data is changed to the data stored in the data storage device 11 through the data management unit 12, but at this time, the unedited data 111 stored in the data storage device 11 and the edited data are Compare the processed data, that is, the edited data 311 edited by the data editing unit 31 of the workstation 3, in the data comparison unit 13,
The data of the changed part, that is, the updated part data 121 is extracted.

At this time, the user can use the display device 32 and user input means 33 of the workstation 3 to add and edit arbitrary comments to the message automatically generated by the message management device 2. The edited message is sent to the mail management device 2 according to the user's instructions, and a message indicating that the data has been updated is automatically generated. The data in the update section is then sent to the network 10 by the mail sending section 22 under the management of the mail management device 2, and sent to other workstations 4 and 5.

[0011] Thereby, the workstations 4 and 5 can recognize by e-mail that the data stored in the data storage device 11 of the database 1 has been updated. FIG. 2 is an explanatory diagram of an example of a data editing window in the workstation 3, in which 30 is a display window, 301 is a data extraction button, 302 is a data storage button, and 303 is a data number. The user specifies the data number in “Number:” and selects the data retrieval button “GET” 301 with the cursor, thereby transferring the data of the specified number from the data storage device 11 of the database 1 via the data management unit 12.

The mail management device 2 automatically generates a message as shown in the figure regarding the received update section data 121. The number of the updated data and the contents of the updated data are already written here as part of the message. In the editing/sending device, it is also possible to add comments by the updater, that is, the user of the workstation 3. The message of FIG. 3 is then emailed to the workstations 4 and 5 of the related users by selecting the send button 304 "SEND".

FIG. 4 is a flowchart illustrating the processing flow of an embodiment of the present invention. In the figure, first, the user accesses the database from the window of the display device of his/her own workstation and reads required data from the data storage device of the database (S-1). If this reading is successful (S-2), edit/update the data (S-3), return it to the database, and update and register the data stored in the data storage device. (S-4). If this registration work is successful (S-5), data before and after editing are compared and changed items are extracted (S-6). The extracted change items (change part data) are transferred to the mail management device, and a mail sheet is automatically created in a preset format and displayed on the user's workstation (S-7).

[0015] Based on this display, the user adds a message as necessary (S-8), and executes mail transmission to other workstations connected to the network (S-9). In addition, if the data reading is not successful in (S-2), an error is displayed (S-10) and the process ends (if necessary, S
-1 and repeat the process). Also, if the registration of update data is not successful in (S-5), an error is displayed (S-11) and the process ends (same as above, if necessary, repeat the process from S-1). repeat).

FIG. 5 is a flowchart illustrating the process of reading data from the database. In the same figure,
The user inputs the data number in a window on the display device of his/her workstation (S-20). Next, the data read button is selected (button press operation) (S-21), and a data read request is sent to the database (S-22). Upon receiving this data read request, the database searches for the requested data from the data storage device 11 via its data management unit, and transmits the search results to the workstation in question (S-23). Note that the processing in the database is not directly related to the present invention and will therefore be omitted. If the search result sent from the database is a successful search, the workstation receives the data (S-26), transfers it to the data editing department (S-28), and performs the process of FIG. Execute. Incidentally, if the search result from the database is "search not successful", this fact is displayed on the display device of the workstation (S-28) and the process ends. Then, if necessary, the process is restarted from (S-20).

[0017] In this way, the fact that a user of a particular workstation has updated data stored in the database and its contents are sent by e-mail to the workstation of the user of the system. , 5 can immediately start work when a work that uses data in the database occurs without checking whether the data used has been updated.

【Effect of the invention】

As explained above, according to the present invention, a user (for example, workstation 4 or 5) who performs work based on data stored in a database
) can immediately recognize data updates executed by the workstation (3), and can smoothly execute required business operations based on the updated data. In other words, users of workstations other than the workstation where the data was updated do not have to check whether the data stored in the data storage device of the database has been updated before starting work, and they do not need to check whether the data stored in the database data storage device has been updated before starting work. Since there is no need to perform the work of checking the update status of the system, the user can concentrate on executing the work concerned, and the work efficiency of the work can be improved.
