Abstract

PURPOSE:To restrict transfer data quantity and to simplify a processing by blocking a record to control it and prepairing a buffer for succeeding insertion and adition at the time of initial blocking. CONSTITUTION:The record is made into a block and controlled, a block number is added to a block 4 and an in-block successive number is added to the respective blockes in the block 4. The block number and the in-block successive number 6 express order. Then, 5 register is executed only to m at the time of newly registering and it is executed only to one at the time of correction registering. A data receipt and delivery unit between computers 1 and 3 is adopted as a block unit and the receipt side computer processes replacement with the block number as a key. By controlling data in this way, an affected range in such a case that the insertion, addition, erasion or order exchange of the record is executed for some block is normally restricted to be one or two.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer system device used for data management.

[0002]

2. Description of the Related Art Conventionally, when it is necessary to order and manage a plurality of records and transfer the data between computers, if the records themselves have the key information for ordering, the It suffices to pass only the changed records and sort them on the receiving computer. However, in the case of data that does not have key information for ordering in the record itself and the actual sequence of records has meaning (the sequence itself represents the sequence), insert / addition / deletion / order change (replacement) Since it is meaningless to transfer the one or two records when performed, usually, a method of transferring and replacing the data all at once by file transfer is often adopted.

[0003]

In the batch data transfer method by file transfer, even if at most one record is inserted into several hundreds of data, several hundreds of data must be transferred. The transmission efficiency is extremely low.

According to the present invention, the amount of data transferred when a record is inserted / added / deleted / changed in order when data such that the actual arrangement of records represents the order is transferred between computers. It is an object of the present invention to provide a computer system device capable of suppressing the above.

[0005]

The present invention provides an ordering function for ordering and organizing a predetermined maximum number of records, and a grouping function for grouping and organizing the records organized by the ordering function. A storage function for storing the records organized by the grouping function and the ordering function, an input / output function for changing the records stored by the storage function to a number smaller than the maximum number of records, and inputting / outputting the records. When the new record read by the output function is different from the previously stored same grouping and the old record in the same order, the grouping discrimination function that discriminates and indicates the corresponding grouping number,
A transfer function that retrieves and transfers only the grouping records designated by the grouping determination function through the input / output function, and the transfer function, the ordering function, the grouping function, the storage function, the input / output function, and the grouping determination function. A first computer equipped with, a grouping identification function for receiving the grouping record sent via the transfer function and identifying the grouping number, and the contents of the grouping record identified by this identification function are revised. And a rewriting function for rewriting to a new record, a display function for displaying record information rewritten by the rewriting function, and a second computer having the display function, the identifying function, and the revising function. It is a computer system device.

[0006]

In the computer system apparatus of the present invention, a predetermined maximum number of records are ordered and organized, and the records organized by the ordering function are grouped and organized by the grouping function and the ordering function. Stored records, changed the records stored by the storage function to a number of records less than the maximum number and input / output, and the same grouping in which the new records read by the input / output function are stored previously, And if it is different from the old record in the same order, the corresponding grouping number is determined and instructed, and only the grouping record instructed by this grouping determination function is extracted and transferred via the input / output function and transferred. The grouping record sent by the function is received, the grouping number is identified, and the grouping record identified by the identification function is Only the revised contents rewritten to a new record, displaying the record information that has been rewritten by the revised function.

[0007]

EXAMPLE An example of the present invention will be described below. In FIG. 1, 11 is an ordering function of ordering and organizing a predetermined maximum number of records, 12 is a grouping function of grouping the records organized by the ordering function 11, and 13 is a grouping function 12 and A storage function for storing the records organized by the ordering function 11, 14 is an input / output function for changing the records stored by the storage function 13 to a record number smaller than the maximum number, and inputting / outputting the record.
Reference numeral 5 is a grouping discrimination function for discriminating and displaying the corresponding grouping number when the new record read by the input / output function 14 is different from the previously stored same grouping and the old record in the same order. , 16 is a transfer function that retrieves and transfers only the grouping records designated by the grouping determination function 15 via the input / output function 13, 1 is a transfer function 16, an ordering function 11, a grouping function 12, a storage function 13 and Input / output function 14
And a first computer 17 having a grouping discrimination function 15,
Is a grouping identification function for receiving the grouping record sent via the transfer function 16 and identifying the grouping number, and 18 is for revising only the content of the grouping record identified by the identification function 17 and writing it in a new record. A revision function for replacing, 19 is a display function for displaying the record information rewritten by the revision function 18, and 3 is a display function 19 and an identification function 17
And a second computer having a revision function 18, which records and manages a plurality of records in an order and manages the records when the data needs to be transferred between the computers. This is a computer system device that realizes to suppress the amount of transfer data at the time of insertion / addition / order change and to simplify the processing by preparing a buffer for later insertion / addition.

That is, when the record is divided into blocks and managed as shown in FIG. Is added, and a serial number in the block is added to the record in each block. Block No. And the serial number in the block represents the order. Here, the actual MA in one block
When the number of X records is 1, and m is the number of MAX records when newly registering to a block (in other words, when some records are blocked for the first time), m
For m and l, the relation of m <l.

That is, at the time of new registration, only m pieces can be registered, and at the time of correction registration, 1 pieces can be registered. Further, the data transfer unit between computers is a block unit, and the receiving computer is a block No.
Perform the process of replacing with the key.

By managing the data by the above means (method), a record can be inserted / added to / from a certain block.
When the deletion / order change is performed, the range of influence is usually limited to one or two blocks.

That is, when m records are registered in a block, up to (lm) records can be inserted / added to the block, and within that range, transfer is performed for one block. Just enough.

When the records of block a and block n are exchanged in order, only block (1) and block n need be transferred. When one record of a block is deleted, ordering is performed if necessary only in that block, and only that block is transferred.

For example, the process management computer 22 having a function (screen) for registering / correcting a work plan and the on-site operation management computer 25 are connected by a premises line, and the work management computer 22 schedules the work plan, Is transferred to the on-site operation management computer 25. (In general, the on-site operation management computer registers the work in the order scheduled by the process management computer and performs various controls, but in an emergency, the work is changed in order.)
There is no key indicating the order, such as date and time.

Under such a system environment, each computer using the present invention has 1 block MA.
X10 record (however, MAX5 record at the time of new registration) manages the work plan for 10 blocks and synchronizes. The process control computer has a work plan setting screen,
In the new registration mode, MA for 1 block (1 screen)
Only X5 work plans can be registered. In fix mode,
Up to 10 MAX can be inserted / added.

[0015]

As described above, according to the present invention, the data transfer amount at the time of correction can always be suppressed to a constant amount, which is useful for simplifying the processing of both computers.
