Abstract

PURPOSE:To automatically and efficiently execute updating by comparing an updating day of a master file of a work station with an updating data stored in a storage device and an updating day of the previous updating data, and detecting an updating omission. CONSTITUTION:Updating of a master file is executed by the following sequence. The updating contents of the master file are registered in a host computer 1. An updating data is transferred to a master file managing system 3 by one- line. At the time of starting an application of work stations 2a, 2b, master files of the stations 2a, 2b are updated. Each updating data is dated, and an updating day of the master files of the stations 2a, 2b is compared with an updating data stored in a storage device of the system 3, and an updating day of the previous updating data, by which an updating omission is detected. In such a way, updating can be executed automatically and efficiently.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a master file management system that automatically updates a master file when master files coexist on a host computer and a workstation. [Prior Art] Conventionally, when a master file is co-located on a host computer and a workstation, updating the master file is done by updating the master file updated on the host computer.
It was transferred to the workstation using a floppy sheet.

[Problem that the invention seeks to solve]

The conventional method of updating the master file using a floppy sheet when the master file coexists on the host computer and workstations requires a considerable amount of manpower and is inefficient when there are a large number of workstations. there were.

This invention was made in order to solve the above-mentioned problem, and aims to provide a system that automatically and efficiently updates online without human intervention.

[Means for solving problems]

The master file management system of the present invention stores master file update data transmitted online from a host computer in a storage device, and stores the update date of the master file of the workstation in the storage device when an application on a workstation is started. Compare the stored update data and the update date of the previous update data,
If the update date matches the latter update date, the update data is read from the storage device and the master file of the workstation is updated.

[Effect]

When updating the master file of each workstation,
Missing updates can also be detected by comparing the update date of the master file of the workstation with the update data stored in the storage device and the update date of the previous update data.

[Embodiments of the Invention] When updating a master file automatically, what must be considered is the timing of updating on the workstation side. Then, check to see if there are any updates on each workstation.

FIG. 1 is an explanatory diagram showing a master file updating method according to an embodiment of the present invention. In the figure, (1) is a real computer, (2a) and (2b) are workstations, and +3U-t master file management system. be.

The master file is updated in the following order.

(1) Register the master file update contents to the real computer.

(11) Transfer the updated data to the management system (3) using the oscillator. (Only once) Qll)
Application F1 on workstation (2a), (2b), workstation (2a),
(2b) Update the master file. (Only once)
Here, if (1) is performed again before (1) is performed, an update will be missed.

The update timing and update omission of the master file on the workstation side are checked as follows.

An update date is attached to each update data, and the update date of the master file of the workstations (2a) and (2b), the update data stored in the storage device of the management system (3), and the previous update data are recorded. The update dates are compared and the procedure shown in FIG. 2 is performed.

In the figure, ■ is the update date of the update data stored in the storage device of the management system (3), ■ is the update date of the previous update data, and O is the update date of the master file of the workstations (2a) and (2b). The current was.

Check whether O matches or not, and if they match, do not update. If they do not match, it is checked whether 0 matches .

〔Effect of the invention〕

As described above, according to the present invention, it is possible to update a master file coexisting on a host computer and a workstation automatically and without overlooking any missed updates, contributing to efficiency. It is highly effective.

[Brief explanation of drawings]

FIG. 1 is an explanatory diagram showing a method for updating a master file according to an embodiment of the present invention, and FIG. 2 is a flowchart showing a check procedure when updating a master file of a workstation. In the figure, (1) is the host computer, (2a), (
2b) is a workstation, and (3) is a master file management system.

Claims (1)

[Claims] This is a system that automatically updates the master file coexisting on a workstation as the master file on the host computer is updated.The system stores update data for the master file transmitted online from the host computer in a storage device, and then updates the master file on the workstation. When the application program of the workstation is started, the update date of the master file of the workstation is compared with the update data stored in the storage device and the update date of the previous update data, and if it matches the update date of the latter, the update date is updated from the storage device. A master file management system that reads update data and updates the master file of the workstation.
