Abstract

PURPOSE:To decrease a file capacity by instructing a master number, inputting data file managing information, identifying the data format of real data based on the control information and executing the editing in accordance with an attribute at every item. CONSTITUTION:By registering data file managing information 2 by a file managing information registering program with an interactive system beforehand, real data 3 can be registered and the data are automatically stored and edited based upon the data file managing information 2. When the user uses the data, a master No.1 is instructed, and the data file managing information 2 of the data can be obtd. The data format of the real data 3 is identified based on the information, edited in accordance with the attribute for an item and the correct data are given to the user. Thus, a file capacity can be decreased.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data management method in an electronic computing system.

[Conventional technology]

Conventionally, computer systems that handle a wide variety of information use a wide variety of data formats, so registration, update, and inquiry programs have been created individually according to the data format, and file areas have been secured according to the format. I had to.

[Problem that the invention seeks to solve]

With the conventional data management method described above, a program must be created for each data format, which requires development man-hours, and file areas must be secured according to the format, resulting in a lot of wasted file area. The drawback is that you have to maintain files for each.

[Failure to solve the problem]

Data management method of the computer system of the present invention Data is managed separately into data file management information and actual data based on a master number, and the data file management information of the data is input by specifying the master number. , has means for identifying the data format of the actual data based on the management information and editing each item according to the attribute.

In this way, by centrally managing many types of data formats, there is no need to develop programs for each data format, and the file capacity can be further reduced.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a data structure diagram of an embodiment of the data pipe system A of the electronic computer system of the present invention.

Data file management information 2 and actual data 3 are managed under a master No. 2, and data file management information 2 has record length, number of items (1 item), item name, and item attribute information.

In addition, since the actual data 3 corresponds to variable length data, it physically has 7 records of 300 bytes and logically has 21 records.
It can store 00 bytes of data.

FIG. 2 is a program function diagram in this embodiment.

The user can register the actual data 3 by registering the data file management information 2 in advance using the file management information registration program in an interactive manner. At this time, the data is automatically stored and edited based on the data file management information 2. When a user uses data, the master number
By specifying t, the data file management information 2 of the data can be obtained. Based on this information, the data format of the actual data 3 is identified.

Each item is edited according to its attributes to provide users with correct data.

〔Effect of the invention〕

As explained above, the present invention has the effect of centrally managing many types of data formats, thereby eliminating the need for program development for each data format and further reducing file capacity.

Claims (1)

[Claims] In a computer system that handles a wide variety of information, data can be managed separately into data file management information and actual data based on a master number, and the data can be managed by specifying the master number. A data management method for a computer system having means for inputting data file management information, identifying the data format of actual data based on the management information, and editing each item according to its attributes.
