Abstract

In a trading data management system including a plurality of clients and a web server connected to the clients via a communications network, when an interruption occurred while the server is receiving data traded in a client for some reason or other, the system restores data that had been transmitted from the client to the server before the interruption of the transmission occurred. The system includes: a unit that receives data traded in one of the clients every time the data is transmitted from the client to the web server; a storage unit that stores the data in a DB server connected to the web server; a unit that determines whether the reception of the trading data has been completed or not; a unit that informs the client that the trading data has not been completely received when the determining unit has determined so; and a unit that returns data stored in the storing unit to the client when the determining unit has determined that the trading data has not been completely received.

Claims

1. A trading data management system, comprising a plurality of clients and a server connected via a communications network, that manages trading data transmitted from the clients to the server, characterized in that the server comprises:

a unit that sequentially receives trading data whenever the data is transmitted from the clients;

a unit that stores the trading data received from the clients;

a unit that determines whether or not the reception of the trading data has been completed; and

a unit that informs the client that the reception of the trading data has not been completed when the determining unit has determined that the reception of the trading data has not been completed.

2. A trading data management system according to claim 1, wherein the server further comprises a unit that returns trading data to the client when the determining unit has determined that the reception of the trading data has not been completed, which data had been transmitted until an interruption of the transmission occurred in the previous transmission, and had been accumulated in the server until the interruption.

3. A trading data management system according to claim 1, wherein the server further comprises a unit that returns trading data to the client before newly receiving trading data from the client when the determining unit has determined that the reception of the trading data has not been completed, which data had been transmitted until an interruption of the transmission occurred in the previous transmission, and had been accumulated in the server until the interruption.

4. A trading data management system according to claim 2, wherein the returning unit comprises a unit that creates screen information involving the trading data to be displayed in the client, and that transmits the created screen data to the client.

5. A trading data management system according to claim 3, wherein the returning unit comprises a unit that creates screen information involving the trading data to be displayed in the client, and that transmits the created screen data to the client.

6. A trading data management system according to claim 1, wherein the storing unit is provided in another server connected to the server.

7. A trading data management system according to claim 2, wherein the storing unit is provided in another server connected to the server.

8. A trading data management system according to claim 3, wherein the storing unit is provided in another server connected to the server.

9. A trading data management system according to claim 4, wherein the storing unit is provided in another server connected to the server.

10. A trading data management system according to claim 5, wherein the storing unit is provided in another server connected to the server.

11. A trading data management system, comprising a plurality of web servers each connected to a plurality of clients via a communications network and a database server connected to the web servers for communication, that manages trading data transmitted from the clients to the web servers, characterized in that the web server comprises:

a unit that sequentially receives trading data whenever the data is transmitted from the clients;

a unit that determines whether or not the reception of the trading data has been completed; and

a unit that informs the client that the reception of the trading data has not been completed when the determining unit has determined that the reception of the trading data has not been completed; and

wherein the database server comprises a unit that stores data received by the receiving unit in the web server.

12. A trading data management system according to claim 11, wherein the web server further comprises a unit that returns trading data to a client when the determining unit has determined that the reception of the trading data has not been completed, which data had been transmitted before an interruption of the transmission occurred in the previous transmission from the client to the server, and had been accumulated in the storage unit in the database server until the interruption.

13. A trading data management system according to claim 11, wherein the web server further comprises a unit that returns trading data to the client before newly receiving trading data from the client when the determining unit has determined that the reception of the trading data has not been completed, which data had been transmitted before an interruption of the transmission occurred in the previous transmission and had been accumulated in the storage unit in the database server until the interruption.

14. A trading data management system according to claim 12, wherein the returning unit comprises a unit that creates screen information involving the trading data to be displayed in the client, and that transmits the created screen data to the client.

15. A trading data management system according to claim 13, wherein the returning unit comprises a unit that creates screen information involving the trading data to be displayed in the client, and that transmits the created screen data to the client.

16. A trading data management method that manages trading data transmitted from a plurality of clients to a server connected to the clients via a communications network in a system comprising the clients and the server, characterized in that the method comprises the steps of:

sequentially receiving trading data whenever the data is transmitted from the clients;

storing the trading data received from the clients;

determining whether or not the reception of the trading data has been completed; and

informing the client that the reception of the trading data has not been completed when the determining unit has determined that the reception of the trading data has not been completed.

17. A trading data management method according to claim 16, wherein the method further comprises the step of returning trading data to the client when the determining step has determined that the reception of the trading data has not been completed, which data had been transmitted until an interruption of the transmission occurred in the previous transmission, and had been accumulated in the server until the interruption.

18. A trading data management method according to claim 16, wherein the method further comprises the step of returning trading data to the client before newly receiving trading data from the client when the determining step has determined that the reception of the trading data has not been completed, which data had been transmitted until an interruption of the transmission occurred in the previous transmission, and had been accumulated in the server until the interruption.

19. A trading data management method according to claim 17, wherein the method further comprises the step of creating screen information to be displayed involving the trading data, and transmitting the created screen data to the client.

20. A trading data management method according to claim 18, wherein the method further comprises the step of creating screen information to be displayed involving the trading data, and transmitting the created screen data to the client.

21. A trading data management program that manages trading data transmitted from a plurality of clients to a server connected to the clients via a communications network in a system comprising the clients and the server, characterized in that the program makes the computer execute the steps of:

sequentially receiving trading data whenever the data is transmitted from the clients;

storing the trading data received from the clients;

determining whether or not the reception of the trading data has been completed; and

informing the client that the reception of the trading data has not been completed when the determining unit has determined that the reception of the trading data has not been completed.
