DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data management system for managing data of an information file, and more particularly to an information file corresponding to an individual household or the like comprising a plurality of personal information data and a relation data table indicating a relationship. The present invention relates to a data management method in which a plurality of data groups are stored.

[0002]

2. Description of the Related Art In this type of data management system, if a householder needs to delete his or her personal data due to emigration or death, etc., simply deleting the personal data of the householder is not enough. There will be households (data groups) that have no household head. Then, a problem occurs such that a search using the householder as a search condition cannot be performed.

[0003]

In the conventional data management system, when it is necessary to delete the personal data of the householder, the operator manually deletes the personal data of the householder and manually deletes the personal data of the householder. While referring to the members, a new head of household was selected and updated. Such an artificial updating process requires a great deal of labor and is not preferable, especially in a large-scale data management system having an information file storing a large number of data groups.

[0004] It is an object of the present invention to provide a data management system capable of updating individual data without imposing great labor on an operator.

[0005]

[0006]

According to the present invention, there is provided an information file in which a plurality of individual data including one specific individual data and a plurality of data groups each comprising a relation data table indicating a relation between the individual data are stored. And data management means for managing the individual data and the data group, wherein the specific individual data is stored in the data management system located at the head of the association data table. Means for receiving the data deletion request to delete the specific individual data,
In the data group to which the specific individual data belongs
Delete the specific individual data, and
Based on data table content and individual data content
Other individual data as new specific individual data
The data management method is characterized in that

According to the present invention, the data management means includes: a group extraction means for extracting the data group to which the specific individual data belongs from the information file based on the data deletion request; A temporary file storing the extracted data group, and deleting the specific individual data from the data group stored in the temporary file, and referring to the relevance data table to the specific individual data. Search for other individual data having a predetermined relevance, and if there is no individual data having a predetermined relevance, search for another individual data having a maximum value of a predetermined parameter with reference to the individual data, and Data updating means for selecting another individual data as new specific individual data and rewriting the data table; Wherein said data groups updated by over data updating means from the temporary file and a group storage means for returning to said information file data management system is obtained.

According to the present invention, the individual data is personal information including age information as the predetermined parameter. Each of the data groups corresponds to an individual household. Represents a relationship between individuals including a spouse relationship as the predetermined relationship, and the specific individual data is located in the head of household on the relationship data table. A scheme is obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A data management system according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a configuration of a data management system according to an embodiment of the present invention. Referring to FIG. 1, the present data management system includes a plurality of household data, which is a data group including a plurality of personal data including personal data of a household head and a relation data table indicating a relation between personal data. Stored information file 20
And data management means 10 for managing personal data and household data. Note that the personal data of the head of the household is located at the top of the relationship data table.

[0011] The data management means 10 automatically updates the personal data of the householder when receiving a data deletion request to delete the personal data of the householder from the operator. That is, when the data management unit 10 receives the data deletion request, the data management unit 10 selects, from the household data to which the personal data of the householder belongs,
The personal data of the head of the household is deleted, and other personal data is selected as personal data of the new head of the household based on the contents of the relationship data table and the contents of the personal data.

More specifically, the data management means 10
Group extracting means 11 for extracting the household data to which the personal data of the household owner belongs from the information file 20 based on a data deletion request from the operator, and a temporary file 1 for storing the household data extracted by the group extracting means 11.
2 and deleting the personal data of the head of the household from the household data stored in the temporary file 12 and searching for personal data having a spouse relationship with reference to the relationship data table,
If there is no spouse's personal data, the personal data with the highest age is searched by referring to the individual data, and the corresponding personal data is selected as the personal data of the new householder and the data updating means for rewriting the data table. 13 and a group storage unit 14 for returning the household data updated by the data update unit 13 from the temporary file 12 to the information file 20.

FIG. 2 is a flow chart for explaining the operation of the data management system. Hereinafter, the operation of the data management method will be described with reference to FIGS.

In step S1, an operator inputs a data deletion request indicating that the head of the household has died or moved out.

In step S2, the group extracting means 11
Extracts from the information file 20 the household data to which the head of the household who has requested the data deletion belongs, and stores the extracted data in the temporary file 12.

At step S3, data updating means 13
Deletes the personal data of the householder from the household data stored in the temporary file 12.

In step S4, data updating means 13
Searches for personal data having a spouse relationship with reference to the relationship data table in the household data. As a result of the search, if there is a spouse, the process proceeds to step S5, while if there is no spouse, the process proceeds to step S6.

In step S5, data updating means 13
Selects the personal data of the spouse as the personal data of the new head of household, and rewrites the relationship of the personal data on the relation data table from the spouse to the head of household.

In step S6, the data updating means 13
Refers to the individual data in the household data, searches for the personal data with the highest age, selects the personal data of the re-elder as the personal data of the new head of household, and the relationship data table of the personal data Rewrite the relationship above to the head of household.

Returns the household data updated by the data updating means 13 from the temporary file 12 to the information file 20.

As described above, the personal data of the head of the household is automatically updated.

[0022]

According to the data management method of the present invention, there is provided an information file storing a plurality of data groups each including a plurality of individual data including one specific individual data and an association data table indicating an association between the individual data; Data management means for managing individual data and data groups, wherein the data management means deletes the specific individual data in the data management method in which the specific individual data is located at the top of the relevance data table When a data deletion request to be received is received, the specific individual data is automatically updated, so that the individual data can be updated without imposing a great deal of labor on the operator.
