2. Description of the Related Art Generally, a batch processing method and an online processing method are adopted as a usage form of a computer (electronic computer).

The batch processing system is a system in which inputs that can be read into a computer are prepared in advance, and they are collectively processed (batch). Especially in the field of business calculation, for example, regarding the shipment volume and sales volume of products, 1
Batch processing such as collecting data for wiring within a certain period such as a week or a month and processing it together on weekends and at the end of the month to create weekly and monthly report materials (shipping table, sales table, etc.) I often use a computer in.

On the other hand, the online processing method is a method in which a processing request can be caught at a location where it is generated and directly input.
For example, when a computer is used for banking or various reservations, the batch processing method is not useful, and this online method has been rapidly used.

By the way, there are cases where such online processing and batch processing are simultaneously executed to update the same file. In such a case, conventionally, the online processing is stopped before executing the batch processing, so that the exclusive control is performed to prevent the illegal update. As a method of stopping the online processing, there are a method of completely stopping the online processing and a method of designating a batch processing time zone for the terminal operator and stopping the operation only during that period.

[0006]

As described above, conventionally, the online processing is stopped before the batch processing, but these methods are methods that depend on the operations of the batch processing operator and the terminal operator. However, there is a problem that the burden on both parties becomes extremely large.

The present invention has been made in view of the above problems, and an object thereof is to perform exclusive control on online processing during batch processing without stopping the online processing and without depending on the consciousness of the terminal operator. It is to provide a data processing device that can be automatically performed.
