Description

  The present invention relates to a data exchange method for exchanging data between systems, and more particularly to a data exchange method and method for exchanging data immediately between systems while maintaining high response by performing asynchronous processing.

  Conventionally, data exchange between systems has been performed as follows.

  For example, data exchange between a general-purpose machine system and an open server machine system is generally performed via a protocol such as FTP (File Transfer Protocol) or remote database access.

  In the case of using FTP, after a series of data is input and processed, a file of the input data is sent to the partner system as a batch file, and the partner system receives the file and performs processing.

  Also, when using remote database access, after entering and processing the data, access the other system's database based on the entered data, receive the return value, and then enter the next data It has become.

  However, the above-described conventional technology has the following problems.

  The first problem is that when the FTP protocol is used, the immediacy of data synchronization with the counterpart system cannot be exhibited. This is because the protocol itself is a protocol that assumes batch file transfer.

  The second problem is that when the remote database access protocol is used, the response at the time of data input cannot be guaranteed. The reason is that the response performance of the process is affected by the load of the counterpart system.

  An object of the present invention is to provide a data exchange method and method that solves the above-described problems and enables immediate synchronous exchange of data between systems while maintaining high response.
