2. Description of the Related Art In recent years, the use of information communication networks has become increasingly diversified and widened. Along with this, communication between computers of different models has come to be realized. The computer has a number of directories (in this specification, the term "directory" simply means a database, and is distinguished from a "distributed directory" in which a directory is provided around a computer). The above directories can be used interchangeably by computers connected to the network.

As described above, when a database in a distributed directory connected in a distributed manner by a network is changed, if the database is used by the distributed directories, databases in other distributed directories are also changed. Must be kept.
Thus, when a change is made to a database in one distributed directory, the change must be communicated to another distributed directory and the database must be changed. Changes to this database were made by telephone or by document.

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

When a database in a distributed directory is changed, it is necessary to make a correction to the database by transmitting the necessary information to another distributed directory. However, when the database in the distributed directory which exists in a distributed manner is corrected by telephone, document, or the like, much effort is required to eliminate the correction mistake.

The present invention has been made to solve the above problems, and eliminates the need for a human to manually modify a database, automatically aligns the databases in each distributed directory, and eliminates the inconsistency of the databases. An object of the present invention is to provide a directory data coordination system.

[0007]

Means for Solving the Problems] [First invention (claim
1 )] The present invention is a distributed directory data coordination system that sends updated contents of one distributed directory among a plurality of distributed directories to another distributed directory. The distributed directory includes update instruction information including data for specifying an update content to be transmitted when the data item is updated and data for specifying a transmission destination distributed directory to which the update content is to be transmitted. A database that is held in association with the data item, a monitoring unit that monitors a user's update operation on the data item, and updates the database corresponding to the data item when the monitoring unit detects an update of the data item. Transmission information creating means for identifying a destination distribution directory based on the instruction information and creating transmission information including an update content for the data item, and transmission information transmitting means for transmitting the transmission information to the specified destination distribution directory It is provided with. [Second Invention (Claim 2)] The present invention is a distributed directory data coordination system that sends updated contents of one distributed directory among a plurality of distributed directories to another distributed directory. The distributed directory contains data for specifying the change contents to be transmitted when the data item is changed and data for specifying the transmission destination distributed directory to which the changed contents are to be transmitted, or the data item is deleted. A database for holding update instruction information including data for specifying a destination distribution directory to which deletion information is to be sent in the case where the deletion information is sent, in association with the data item, and a case where the data item of the database is updated. Transmission information creation means for identifying a destination distribution directory based on update instruction information of the database corresponding to the data item and creating transmission information including an update content for the data item; and And transmission information transmitting means for transmitting the transmission information. [Other inventions (claims 3 to 6 , claim 7 and
8 )] The present invention (claims 3 to 6 ) is the first invention or the second invention.
It has a configuration including the invention. The present invention (claim 7
Beauty 8) corresponds the first invention, the second shot bright to those expressed as a method invention, respectively.

[0008]

[Operation] The database in the distributed directory holds data items and update instruction information corresponding to the data items. When an update process such as change or deletion is performed on a data item, the transmission information creating unit checks whether or not the data item includes update instruction information. The update instruction information is attribute information of the updated data. For example, when the data includes a plurality of predetermined items,
It is attached corresponding to a specific data item (one or more). In the example of FIG. 5 described later, each data (entry) has data items such as “business office”, “manager”, “location”, and so on. Information is attached. The update instruction information indicates that the value of the business office should be sent to the upper distributed directory when this data item has “changed”, and that the value of the business office should be transferred to the upper distributed directory when it has been To inform. When it is determined that the update instruction information is included, the transmission information creation unit creates the transmission information according to the update instruction information. The transmission information includes the destination of the transmission information and the updated content. For example, as shown in FIG.
Destination ("Distributed directory 1", "Responsibility = East Japan"),
Transmission information including the details of the update (“lower order change”, “sales office = Tochigi east”) is created. Then, the created transmission information is sent to the distribution directory of the destination by the transmission information sending means, and the data in the distribution directory of the destination is updated based on the transmitted transmission information.

[0009]

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 by an information processing device centered on a computer (not shown). Of the distributed directories 1 to 4,
The distribution directory 2 is shown as a representative. That is, the distributed directories 1 to 4 monitor whether data in the database has an update process such as update or delete, and include update instruction information for sending 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 an update content, and updating the update packet created by the update packet creation device 12 It comprises a packet transmitting device 13 for transmitting to a packet destination and a directory 14 which stores a database and has a database management function. The connection of the distributed directories 1 to 3 may be as shown in FIG.

FIG. 3 shows a specific example of the information area managed by the distributed directories 1 and 2. In the information area 31 managed by the distributed directory 1, the headquarters = sales headquarters are located at the upper level, and the lower level is connected to responsible = overseas, responsible = western Japan, responsible = eastern Japan, etc. In the information area 32 managed by the distributed directory 2, there are a sales office = Tokyo, a sales office = Tochigi, and an office = Chiba. . Then, as shown in FIG. 4, the information structure in the entry in charge of “East Japan” is, as shown in FIG. As the description of the distributed directory 2. In other words, the upper level in charge of East Japan is the sales headquarters and its address is distributed directory 1, the lower level in charge of East Japan is the Hokkaido office and its address is distributed directory 1, and the lower level in charge of East Japan is the Tokyo office and Tochigi office, In the Chiba sales office, the address indicates that each is a distributed directory 2.

The monitoring device 11 monitors whether a change / deletion among operations performed by the user with respect to the directory 14 has been performed. The information structure in the entry of Tochigi Sales Office is
It has a configuration as shown in FIG. That is, in addition to information on items such as a sales office, a manager, a location, and a higher rank, when change or deletion is performed, update instruction information indicating an address to which an update packet is to be transmitted and an update content are required. Has been added to the item. In the example of FIG.
Information on the destination at the time of change, the content, and the address at the time of deletion are added as update instruction information. This additional information can be set by a system administrator. The user searches the directory 14 and calls the entry of “sales office = Tochigi” shown in FIG. 5, and sets the value of the office to “Tochigi”.
Is changed to "Tochigi Higashi". The monitoring device 11 detects the operation, changes the value of the office to Tochigi-higashi, and sets the update destination to the item of “higher” (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 that changes 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 shown in FIG. 6A, the destination is the distributed directory 1 at the higher rank, the entry to be updated is responsible for East Japan, and the lower level of East Japan is changed. Is indicated to be changed. Also, in FIG. 5, when the user deletes the contents of the item of the sales office, similarly, FIG.
(B) 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 or not the user has “updated” the entry in the directory 14. When the monitoring device 11 detects that the entry has been updated, the process proceeds to the next step.
If there is no "update", the monitoring is continued (step 7).
1).

When the monitoring device 11 detects that the entry of the directory 14 has been "changed or deleted", another distribution such as "change" or "delete" is performed on the entry. It is determined whether update instruction information has been added to the directory (step 72).

When the item of the entry with the update instruction information is changed or deleted, the update packet creation device 12 transmits the update packet in accordance with the instruction of the item, that is, the destination and the update content shown in FIG. It is created (step 73).

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

Then, in the distributed directory 1, the directory 14 therein is automatically updated. That is,
In the directory 14, by the management function of the directory 14, for example, the data of the database is deleted 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 in the distributed directory according to the present invention has been described in the case where the information is linked from the upper level to the lower level by a link. However, the same applies to the case where the information of the distributed directory is parallel or overlapped.

[0019]

According to the present invention, when data in a database in a distributed directory is updated, inconsistency of data generated between the distributed directories can be achieved without humans exchanging complicated messages. Can be automatically matched so as not to be.
