Next, the operation of the program-based record division management system of the present embodiment thus configured will be described with reference to the drawings.

FIG. 2 is a flow chart showing a concrete program execution process by the program-based record division management system of this embodiment.

In FIGS. 1 and 2, for example, it is assumed that the record storage device 7 has a file named file A in which a plurality of records each having a record length of 200 bytes exist.

First, the record area designating means 1 in step 11 reads "1 in the record of file A in program A".
The information indicating which area of the record of the file handled by the program "Use a specific record area of 51 bytes to 200 bytes" is registered.

In the record area instruction storage device 2 in step 12, the information "in program A uses a specific area of 151 bytes to 200 bytes of the record of file A" instructed in step 11 is registered.

It is assumed that the program execution application means 3 in step 13 is instructed to execute the "program A using the file A".

The program execution instruction analysis means 4 in step 14 analyzes the name of the program applied in step 13, and receives the information of the analyzed program name "program A" in the record area instruction acquisition means 5 in step 15. hand over.

In step 15, the record area designation information for the program A stored in step 12 is retrieved by the name of the program "program A" passed from step 14, and "program A stores the record of file A". The specific area from 151 bytes to 200 bytes is used "is taken out.

In the fetched record area instruction storage device 6 in step 16, "from program 151, from the 151 bytes of the record of file A to program 2 retrieved in step 15,
The information "use a specific record area up to 00 bytes" is stored.

The record reading means at step 18 reads one record from the file A registered at step 17 according to the execution instruction applied at step 13.

In the record dividing means 10 in step 19, the record read in the main memory in step 17 is stored in step 16 "In the program A, the specific record area of 151 bytes to 200 bytes of the record of the file A is stored. According to the information “use”, the record of the specific record area of 50 bytes from 151 bytes to 200 bytes is divided.

Record passing means 10 in step 20
Then, only the 50-byte specific record area from 151 bytes to 200 bytes of the record of the file A divided in step 19 is transferred to the program A.

As described above, according to the record division management system by program of the present invention, only a specific record area in a file designated in advance for each program is transferred to the corresponding program at the time of executing the program, and the program is executed at the time of executing the program. By passing only the specific record area in the file specified for each program to the relevant program, it becomes very easy to build a database that requires specialized knowledge, and it is easy for all program developers or system operators. Can do the work to
Further, even if the specific record area used by the program is changed, it can be dealt with only by changing the instruction of the specific record area, and there is no need to rebuild the database.

In the case of the conventional file, there is a problem in that the record area which is not required by the program is read in the program so far, so that there is a problem in effective use of the main memory, but it is instructed for each program. Since a specific record area in a file is passed to the corresponding program, unnecessary buffer area is reduced and main memory can be effectively used. In the conventional case, it is necessary for each program to effectively use main memory. It was difficult to centrally manage the data and create the file because only the areas were collected and created as separate files, but it is possible to specify and use only a specific record area in the file for each program. Therefore, it is not necessary to create a separate file for each program, which facilitates centralized management of data and creation of files.

As described above, if only the specific record area in the file designated for each program is designated and registered in advance when the program is executed, only the specific record area is handed over to the program, so that the database is constructed. Also, since it is not necessary to reconstruct, effective use of main memory is possible, and moreover, centralized management of data and creation of files are easy, so effective use of data, effective use of main memory, program development and system operability The effect is that it can be greatly improved.
