Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention involves update processing such as modification or deletion of data in a database in one distributed directory interconnected by a computer network such as OSI (Open System Interconnection). The present invention relates to a distributed directory knowledge matching system for automatically matching data in a database in another distributed directory.

[0002]

2. Description of the Related Art In recent years, the usage patterns of information communication networks have become more diverse and widespread. Along with this, communication between computers of different models has come to be realized. The computer has many directories (in the present specification, when simply described as “directory”, it means a database and is distinguished from “distributed directory” in which directories are provided around the computer). Any computer connected to the network can use the above directories mutually.

In this way, when the database in the distributed directories connected in a distributed manner by the network is changed, if the database is used among the distributed directories, the databases in other distributed directories are also changed. I have to keep it.
In this way, when a database in one distributed directory is changed, the change must be communicated to another distributed directory and the database also needs to be changed. Changes to this database were made by telephone or in writing.

Further, as documents related to the present invention, for example, Japanese Patent Laid-Open No. 62-160549, which describes a file management method in which a user establishes an attribute in a new file whenever necessary, or a distributed directory is described. ISO / IEC 9 that describes the basic method of
594-1 to 4, 1989.

[0005]

When the database in the distributed directory is changed, it is necessary to notify the other distributed directories as needed and to modify the database. However, when the database in the distributed directories that exist in a distributed manner is modified by telephone or documents, a lot of labor is required to eliminate the correction error.

The present invention is intended to solve the above problems and eliminates manual work for modifying the database, automatically aligns the databases in each distributed directory, and eliminates inconsistencies in the database. It aims to provide a knowledge matching system for directories.

[0007]

In order to achieve the above object, a distributed directory knowledge matching system according to the present invention can update data in a database in one distributed directory among distributed directories existing in a distributed manner. If there is, it is a distributed directory knowledge matching system that matches the updated database with the databases of other distributed directories, and monitors the update processing of the data in the database in the distributed directory and executes the update processing. A monitoring device (11) for monitoring whether or not the data in the database includes update instruction information for instructing to send the update content for matching with the database in another distributed directory to the database; The device determines that the above update instruction information is included. At this time, the transmission information creation device (12) that creates the transmission information consisting of the destination to the other distributed directory that needs to be updated and the update content, and the transmission information created by the transmission information creation device as the destination of the transmission information. It is composed of a transmission information transmitting device (13) for transmitting.

[0008]

[Operation] The monitoring device in the distributed directory constantly monitors whether or not the data in the database in the distributed directory is updated, such as changed or deleted.
Further, when the data is updated, the monitoring device determines whether or not the data includes update instruction information. The update instruction information is attribute information of the updated data, and is attached corresponding to a specific item (one or more) when the data includes a plurality of predetermined items, for example. Taking FIG. 5 which will be described later as an example, each data (entry) is “sales office”, “director”, “location” ...
・ There are data items such as
Update instruction information is attached. When there is "change" in this data item, the update instruction information instructs to send the value of the sales office to the upper distributed directory and "delete".
If there is, it means to notify it to the higher distributed directory. When the monitoring device determines that the update instruction information is included, the monitoring device passes the update instruction information to the transmission information creating device. The transmission information creation device creates transmission information according to the update instruction information. The transmission information includes a destination and update contents of the transmission information. For example,
As shown in FIG. 6, the destination (“distributed directory 1”,
Transmission information including “person in charge = East Japan”), updated contents (“subordinate change”, “sales office = Tochigi East”), etc. is created. Then, the created transmission information is sent by the destination from the transmission information sending device to the destination distributed directory, and the destination distributed directory updates the data therein based on the sent transmission information.

EXAMPLE FIG. 1 is a block diagram of a distributed directory according to the present invention. In FIG. 1, each of the distributed directories 1 to 4 is configured as a database of information processing equipment centered on a computer (not shown). Of the distributed directories 1 to 4,
The distributed directory 2 is shown as a representative. That is, the distributed directories 1 to 4 include update instruction information for monitoring whether the data in the database has an update process such as update or deletion, and sending the update information to another database. A monitoring device 11 for monitoring whether or not there is an update packet, an update packet creation device 12 for creating an update packet composed of a destination to another distributed directory and update contents, and an update packet created by the update packet creation device 12 The packet transmitting device 13 for transmitting to a packet destination and a directory 14 that stores a database and has a database management function are respectively configured. Also, the connection of the distributed directories 1 to 3 may be as shown in FIG.

A specific example of the information area managed by the distributed directories 1 and 2 is shown in FIG. In the information area 31 managed by the distributed directory 1, there is a head office = sales headquarters at a higher level, and a lower level is connected with a person in charge = overseas, a person in charge = west Japan, a person in charge = east Japan, and the like. The information area 32 managed by the distributed directory 2 has a sales office = Tokyo, a sales office = Tochigi, and a sales office = Chiba, each of which is connected to a person in charge = eastern Japan, which is a higher rank in the distributed directory 1, by a link. . As shown in FIG. 4, the information structure in the entry of the person in charge = East Japan is, as shown in FIG. 4, the headquarters = the sales headquarters of East Japan and the distributed directory 1 as its address, and the sales office names and addresses of East Japan. As described in the distributed directory 2. That is, the top of East Japan in charge is the Sales Headquarters, the address is distributed directory 1, the bottom of East Japan is in Hokkaido Sales Office, the address is distributed directory 1, and the bottom of East Japan in charge is Tokyo Sales Office and Tochigi Sales Office. At the Chiba office, the addresses are shown to be the distributed directory 2.

The monitoring device 11 monitors whether the user has changed / deleted the operations performed on the directory 14. The information structure in the Tochigi office entry is
It has a structure as shown in FIG. That is, in addition to information on items such as a sales office, a director, a location, and a higher rank, update instruction information for instructing a destination to which the update packet is to be sent and the content of the update when the change or deletion is necessary is required. It is added to the item. In the example of Fig. 5, the item of sales office is
Information about the destination when changing, the contents, and the destination when deleting is added as update instruction information. This additional information can be set by the system administrator. The user searches the directory 14 and calls the entry of “sales office = Tochigi” shown in FIG. 5, and sets the sales office value to “Tochigi”.
It is assumed that the operation to change from "Tochigi Higashi" is performed. The monitoring device 11 detects the operation, changes the value of the business office to Tochigi Higashi, and sets the update destination to the item "upper" (charge = east Japan, address = distributed directory 1). This is notified to the update packet creation device 12.

The update packet creating device 12 creates a packet for changing the item in the directory 14 in another distributed directory 1 based on the notified information. That is, in the update packet creation device 12,
The packet shown in FIG. 6A is created. That is,
In the packet of FIG. 6A, the destination is the higher-level distributed directory 1, the update target entry is in charge = eastern Japan, the lower level of the eastern Japan is changed, and the changed contents are the sales office item Tochigi Higashi. It indicates that it is an instruction to change. Further, in FIG. 5, when the user deletes the contents of the item of the sales office, the same process as in FIG.
(B) packet is created and transmitted.

Next, the operation of the present invention will be described with reference to the flowchart of FIG. The monitoring device 11 in the distributed directory constantly monitors whether the user has “updated” the entry in the directory 14 or not. Then, when the monitoring device 11 detects that there is "update" in the above entry, the process moves to the next step,
If there is no "update", continue monitoring (step 7).
1).

Further, when the monitoring device 11 detects that the item of the entry of the directory 14 is "changed or deleted", the item of the entry is changed to another distribution such as "change" or "delete". It is determined whether or not the update instruction information for the directory is added (step 72).

When the item of the entry with the update instruction information is changed or deleted, the update packet creating device 12 creates the update packet according to the instruction of the item, that is, the destination and the update content shown in FIG. Create (step 73).

When the information that is not the item marked with an entry is updated, the monitoring device 11 continues the monitoring. The update packet created by the update packet creating device 12 is sent from the packet sending device 13 to the destination distributed directory according to the destination, for example, in the case of the update packet in FIG. 6, the distributed directory 1 (step 74).

Then, in the distributed directory 1, the directory 14 therein is automatically updated. That is,
In the directory 14, for example, the management function of the directory 14 deletes the data in the database according to the instruction of the packet, and the link a connecting the distributed directory 1 and the distributed directory 2 is removed.

The information managed by the distributed directory of the present invention has been described in the case where the links are linked from the upper level to the lower level, but the same applies to the case where the information in the distributed directory is parallel and the information is duplicated.

[0019]

As described above, according to the present invention, when the data in the database in the distributed directory is updated, there is no inconsistency in the data generated between the distributed directories without humans exchanging complicated messages. It can be automatically matched so that it does not exist.
