Trading data management system, method and program therefor

摘要

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.
