Generally, in an information system, an administrator of the system (hereinafter referred to as a "system administrator") replaces an AP with the establishment or abolition of the service provided by the system. AP management is required. Further, the system administrator also needs to perform information management of static information, such as addition of new data and deletion of unnecessary data, on a regular basis, for example, about once a month.

When the system administrator performs the above-mentioned AP management and information management (hereinafter, both are collectively referred to as "computer resource management"), in the client-server type information system, all client devices constituting the system are included. It is necessary to manage computer resources for. Therefore, in a large-scale system in which the number of client devices is several thousand, this computer resource management becomes a very difficult and complicated task. On the other hand, W

However, since the Web type information system is arranged only in the server device even if the static information is not updated for a certain period of time, an inquiry is made to the server device every time the static data is searched. There is a need to do. For this reason,
In the Web-type information system, the communication traffic between the client device and the server device significantly increases as compared with the client-server type information system. Furthermore, the Web
The type information system, due to the increase in communication traffic,
There is a problem that the information processing performance of the entire system is significantly deteriorated.

Conventionally, as a method of solving the above-mentioned problems of the Web type information system, a method of reducing communication traffic by improving the performance and multiplexing of the communication line has been used. However, in recent years, there are not a few companies that carry out activities on a global scale, and the communication lines that make up the information systems of such companies are spread around the world. In such a case, the cost required for improving the performance and multiplexing of the communication line becomes enormous, and it is practically impossible to adopt the above method.

The present invention has been made in view of the above-mentioned problems, and reduces communication traffic between a client device and a server device while maintaining ease of computer resource management, which is an advantage of the Web-type information system. The purpose is to provide such information system.

The number of divisions can be specified by entering the number of cases in 3. Furthermore, the system administrator can perform input operations such as pressing the split button 74 and the end button 75. When the system administrator performs some input operation, CP
U21 receives the operation content of the system administrator via the input device 23 (step SA2), and the CPU 21 determines the operation content (step SA3). That is, whether the operation content is pressing the split button 74 (hereinafter referred to as “division operation”), pressing the end button 75 (hereinafter referred to as “end operation”), or an operation other than the division operation or the end operation ( Hereinafter, it is determined as "other operation").

If it is any other operation, the CPU 21
Displays the split processing screen based on the operation content.
Is again displayed (step SA1), and the input operation from the system administrator is again waited for. If it is a division operation, the CPU 21 generates a division table based on the target information, target items, and the number of divisions displayed on the division processing screen (step SA4). Specifically, employee information is selected as target information, a department name is selected as a target item, and the number of divisions is 100 on the division processing screen.
When is set, the CPU 21 first groups all the employee data stored in the employee information for each employee data having the same department name, and further groups each group with 100 employees. Create a contingency table by subdividing into groups containing data. The CPU 21 has a serial number starting from 1 for each division table (hereinafter referred to as "division number").
Are stored in the volatile memory 26. If the operation content is an end operation, the division process ends.

At step SA5 which is executed after step SA4, the CPU 21 and the employee data stored in the contingency table created at step SA4 and the step SA4.
The index table 8 shown in FIG.
1 is generated and stored in the volatile memory 26. As shown in FIG. 8, the index table 81 stores the employee number and the division number in association with each other.

Next, the CPU 21 reads the index class from the class library into the volatile memory 26 using the JVM, and creates it in the data part 52 of the index class in step SA5 using the data storage method of the index class. The index table is stored and stored in the data storage area 271 of the storage device 27 (step SA6).

Next, the CPU 21 performs substantially the same processing as in step SA6, stores the contingency table generated in step SA4 in the division class data section 52 to generate a division class (step SA7), and executes the division processing. finish.
