Abstract

PROBLEM TO BE SOLVED: To reflect the revision of a diverting source to a diverting side after the change/deletion of the diverting side by preparing diverting substance data from diverting side data and a changing difference between the diverting side and the diverting source based on a changing priority record. SOLUTION: When the contents of diverting source data 1 and diverting side data 2 are the same, the changing priority record 8 is prepared by a changing priority record preparing means 11 with respect to all the items. At this time diverting source data 1 is preferred in principle and a difference preparing means 5 prepares a difference 6 with respect to the change of diverting source data 1. On the other hand, concerning change to diverting side data 2, a difference preparing means 3 prepares a difference 4 and at the time of preferring this change, the changing priority record preparing means 11 records a pertinent item in the changing priority record 8. Diverting substance data 9 is prepared by a substance preparing means 7 by using diverting side data 2, the difference 4 and the difference 6. When change/deletion exists at the same item of the diverting side and a diverting source, the changing priority record 8 validates a preferred one to prepare diverting substance data 9.

2. Description of the Related Art Conventionally, when diverting data, it is premised that the diverted side and the diverted source have the same content, and if the diverted source is changed, the content will not be reflected on the diverted side at all, or it will be diverted. The original contents are reflected as they are on the diversion side, and the changes on the diversion side are completely lost.

[0003] For example, Japanese Patent Laid-Open No. 5-346882 secures data consistency between distributed computers. However, the diversion source and the diversion side have the same contents, and the diversion source and the diversion side have different contents. Cannot be

[0004]

In the above-mentioned conventional data diversion system, when the diversion side makes a correction, it is difficult to reflect the revision of the diversion source on the diversion side and to use it as it is.

The reason is that there was no means for reflecting the revision of the diversion source on the diversion side.

BEST MODE FOR CARRYING OUT THE INVENTION Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a data diversion apparatus and method with a data change function according to the present invention.

Prior to diversion, the minimum unit of change / deletion (hereinafter, “item”) is determined on the diversion source / diversion side. This is used when creating a difference. The diversion source data 1 is used as the diversion side data 2. That is, the diversion source data 1 and the diversion side data 2 have the same contents. At this time, the change priority record creating unit 11 creates the change priority record 8 indicating the priority for all items. At this time, in principle, all items of the diversion source data 1 have priority. At the diversion source, the difference creating means 5 creates the difference 6 with respect to the change of the diversion source data 1. Similarly, with respect to the change to the diversion side data 2, the difference creating means 3 creates the difference 4, but when giving priority to this change, the change priority record creating means 11 gives priority to the corresponding item and the change priority record. Record at 8. The diversion original data 10 can be represented in the form of diversion original data 1 + difference 6 (means for creating the diversion data 9 is outside the scope of the present invention, and therefore omitted from FIG. 1). The entity creation means 7 creates the difference 4 and the difference 4
And the difference 6 are used. When there is a change / deletion in the same item of the diversion side and the diversion source, the prioritized one is validated by the change priority record 8 and the diversion substance data 9 is created.
That is, the diversion side data 2 is recreated.

[Table]

First, when there is no change in the diversion source / diversion side in the state 1 shown in the table, there is no change in the diversion source item in FIG.
As shown in the block diagram in the case where there is no change in the diversion side item, there is substantially no difference, but the difference creating means 3 creates a difference 4
Is created. The diversion entity data A91 is created by the entity creation means 7 based on the diversion side data 2 and the difference 4, but the diversion side data 2 and the diversion entity data A91 have the same contents.
