Abstract

Provided in one embodiment of the present invention is a computer system including a database server and a terminal device for communicating with the database server; the said database server retaining a database; and the terminal device including: an interface for receiving data, which is stored in the database retained in the database server, via a communication network; a buffer for storing the data received by the interface in order to display the data in a window which is to be displayed on a display device; and a controller for starting saving the data, which is stored into the buffer, in a file at a time interval, with the window being displayed on the display device being as a trigger.

Claims

1. A terminal device, comprising:

an interface for receiving data, which is stored in a database retained in a database server, via a communication network;

a buffer for storing the data received by the interface in order to display the data in a window which is to be displayed on a display device; and

a controller for starting saving the data, which is stored into the buffer, in a file at a time interval, with the window being displayed on the display device being as a trigger.

2. The terminal device according to claim 1, wherein the buffer stores a part of the data stored in the database.

3. The terminal device according to claim 2, wherein:

the data stored in the database is associated with an identification number of an operator of the terminal device; and

the buffer stores data which is associated with the identification number of the operator of the terminal device, among the part of the data stored in the database.

4. The terminal device according to claim 1, wherein when the window is closed, the controller stops saving the data, which are stored on the buffer, in the file at the time interval.

5. The terminal device according to claim 1, wherein before saving the data, which is stored in the buffer, in the file at the time interval, the controller locks the data stored in the buffer to perform exclusive control on an operation of changing the data.

6. The terminal device according to claim 1, wherein the controller regularly saves data in the buffer, in the file.

7. The terminal device according to claim 1, wherein the data saved in the database represents a buy offer of foreign exchange of a limit order, and the controller adjusts the time interval at which the data stored on the buffer is saved in the file in accordance with a rate fluctuation degree of the foreign exchange.

8. The terminal device according to claim 7, wherein the rate fluctuation degree the foreign exchange is received via the communication network.

9. The terminal device according to claim 1, wherein the data, which is stored in the buffer, is saved in the file in a CSV format.

10. The terminal device according to claim 1, wherein the data saved in the file is manipulated by an application which is installed in the terminal device or is accessible from the terminal device.

11. A computer system comprising a database server and a terminal device for communicating with the database server;

the said database server retains a database;

the terminal device comprising;

an interface for receiving data, which is stored in the database retained in the database server, via a communication network;

a buffer for storing the data received by the interface in order to display the data in a window which is to be displayed on a display device; and

a controller for starting saving the data, which is stored into the buffer, in a file at a time interval, with the window being displayed on the display device as a trigger.

12. The computer system according to claim 11, wherein the buffer stores a part of the data stored in the database.

13. The computer system according to claim 12, wherein:

the data stored in the database is associated with an identification number of an operator of the terminal device; and

the buffer stores data which is associated with the identification number of the operator of the terminal device, among the part of the data stored in the database.

14. The computer system according to claim 11, wherein when the window is closed, the controller stops saving the data, which are stored on the buffer, in the file at the time interval.

15. The computer system according to claim 11, wherein before saving the data, which is stored on the buffer, in the file at the time interval, the controller locks the data stored on the buffer to perform exclusive control on an operation of changing the data.

16. Tangible computer readable storage having computer readable software embodied thereon for causing a computer to:

receive data, stored in a database retained in a database server connected to the computer via a communication network, the data being received by means of an interface via the communication network connected to the computer;

store the data received by the interface on a buffer in order to display the data in a window which is to be displayed on a display device connected to the computer; and

start saving the data, which is stored on the buffer, in a file at a time interval, with the window being displayed on the display device as a trigger.

17. The tangible computer readable storage according to claim 16, wherein the buffer stores a part of the data stored in the database.

18. The tangible computer readable storage according to claim 17, wherein:

the data stored in the database is associated with an identification number of an operator of the terminal device; and

the buffer stores data which is associated with the identification number of the operator of the terminal device, among the part of the data stored in the database.

19. The tangible computer readable storage according to claim 16, wherein when the window is closed, the controller stops saving the data, which are stored on the buffer, in the file at the time interval.

20. The tangible computer readable storage according to claim 16, wherein before saving the data, which is stored on the buffer, in the file at the time interval, the controller locks the data stored on the buffer to perform exclusive control on an operation of changing the data.
