Description

[Detailed Description of the Invention] (1) Technical Field of the Invention The present invention relates to a data processing method, and in particular, accesses a host device from a terminal device, and accesses the same file again to the host device based on the access result. The present invention relates to a data processing method in which access is sometimes performed based on in-process data obtained from a previous access.

(2) Prior art and problems Conventionally, in banking-related operations, when conducting transfer transactions or transfer transactions, data is exchanged between a host device at a center and terminal devices such as teller devices at each bank. .

For example, when making a transfer transaction, the customer submits a transfer slip in which the name of the bank branch to which the transfer is to be made, the account number, the amount to be transferred, etc. are entered. Looking at this transfer slip, the operator operates the teller device 1 shown in FIG. 1 to input the name of the bank branch to which the transfer is to be made, the account number, the amount to be transferred, etc. This input data is transmitted from the terminal controller 2 via the line section 3 to the host device 4 of the center, and is stored in the account file 5 based on the bank name, account number, etc.
The authenticity check is performed, that is, whether the account is registered as a bad account 5-1, whose account it is, etc. are read out, and the fee for the transfer is calculated and sent to the teller device 1. sent to. Note that the bad account here refers to, for example, a stolen magnetic card or an account that has been fraudulently registered. The data sent from the host device 4 to the teller device 1 is displayed on the display of the teller device 1, so the operator is informed that this is a non-defective account and the account name written on the slip. Check whether the name is the same as the registered name.

After confirming these, the operator again inputs the transfer destination account number and transfer amount from the counter device, and presses the approval key. As a result, the host device 4 calculates the fee again and holds it separately, accesses the same part of the same account file 5, adds the transfer amount to it, and registers new data.

In other words, once a data transaction from a terminal device (for example, a teller device) is completed, the host device in a financial institution does not retain the transaction data, that is, the read data and calculation data sent to the terminal device. After accessing the account file or calculating the fee, the user must access the account file again to read out whether the accessed account is a bad account, and perform the same fee calculation again. Therefore, there is a problem in that the load on the host device 4 of the center increases, and the data processing efficiency inevitably decreases. (This is because in data processing systems related to financial institutions, even if a terminal device inquires about the data that was being processed when the host CPU goes down, that is, the data that is in progress, there is no way to answer accurately, so no response is received.) (3) Purpose of the Invention Therefore, as described above, the purpose of the present invention is to prevent the same access or the same operation from being performed again. It is an object of the present invention to provide a data processing method that lightens the load on a center device in this manner.

(4) Structure of the Invention For this purpose, the data processing method of the present invention includes a terminal device having data input means, a terminal control device, and a host processing device that performs data processing requested by the terminal device. In the data processing method that performs transaction processing by checking the validity of data based on data input from the terminal, the host processing device is provided with transmission data holding means, and the terminal control device is provided with data holding means and comparison means. and temporarily transmits the result of the validity check and the in-process data that the terminal device can use and that the host processing device has in response to the first data processing request from the terminal device to the data holding means. At the same time, a second data processing request is made from the terminal device to the host processing device, and the comparing means determines whether the data from the terminal device and the data held in the data holding means and transmitted from the host processing device match. When obtained, the in-process data is transmitted to the host processing device, and data processing in the host processing device is performed based on this data.

The fee is calculated based on the identification information of this store and other stores of the account transmitted from 3.

The transmission register 21 is a register that temporarily sets data to be output from the host device.

The first search unit 22 searches whether or not the transmitted account number is a bad account written in the bad account file 25, and if it is not a bad account, it outputs "None" and if it is a bad account, it outputs "None". If so, “Yes”
Output.

The second search unit 23 identifies whether the transmitted account number belongs to this bank or another bank, and
While transmitting the other store identification signal to the calculation unit 20,
For accounts with this bank, please refer to the account file 24.
and outputs the account holder name, address position, etc. to the transmission register 21.

The account file 24 is a file in which the bank account is written, and corresponds to the account file 5 in FIG.

The bad account file 25 is a file in which, for example, a stolen magnetic card or other account number that may be misused is written, and corresponds to the bad account 5-1 in FIG.

The data holding register 26 is a register that temporarily holds the data held in the data holding register 13 of the terminal controller, and is composed of a plurality of sections 26-0 to 26-5, etc.
For example, the account number is entered in section 26-0, the presence or absence of a bad account file is entered in section 26-1, the fee is entered in section 26-2, and
In the section 26-3, the name of the account member is written, in the section 26-5, the amount of transfer (remittance), etc. is written, and in the section 26-4, other data such as file name and total amount are entered. In some cases, the address etc. may be entered.

The gate 27 outputs the data written in the data holding register 26 if the account number is not held in the bad account file 25.

The first updating unit 28 is for writing data into the account file 24. The data necessary for writing is held in the data holding register 26, and the data necessary for this updating is passed through the gate 27. Various data are transmitted.

The second updating unit 29 updates the fee file 30.

The fee file 30 is for storing the amount of fees for that day.

Next, the operation shown in FIG. 2 will be explained.

First, the transferor submits the required amount of money to the bank counter along with the transfer request form. The operator then uses the keyboard 6 to input the account number (including bank branch name) and amount to be transferred, etc.
Set these in data register 9, then press the send key. This allows AND gate 1
When the transmission key signal "1" is applied to 2 and
The gate 12 is turned on, and the account number and amount set in the data register 9 are transferred to the line section 1.
8, and the host device's data/
Set in register 19.

Based on the account number set in section 19-0 of data register 19, first search section 22 and second search section 23 operate. Then, the first search unit 22 searches the bad account file 25 to check the validity and detects whether or not the account number exists in the bad account file 25. If it is detected, "existence" must be detected. Outputs "None". In this case, since this account number does not exist in the bad account file 25, "None" is output. Also, the second search section 23
identifies whether the account is with this bank or another bank based on this account number, and outputs the identification result to the calculation unit 20. For example, a present/other store identification signal indicating that the account is with the present bank is output to the calculation unit 20. And if this is our bank account,
Read the contents from the account file 24,
The account holder, the total amount up to that point, etc. are extracted, and together with these, the file name, address data, etc. in which the account is written are output to the transmission register 21. Furthermore, the calculation unit 20 receives the transfer amount from the section 19-1 of the data register 19 and the identification signal for our store and other stores from the second search unit 23, so it calculates the transfer fee based on these and Send register 21
to communicate. At this time, the account number and amount are transmitted to the transmission register 21 from the data register 19. When the necessary data is set in the transmission register 21 in this way, each of these data is held in the data holding register 13 of the terminal controller via the line section 18.

When each piece of data output from the host device is set in the data holding register 13 in this way, the account number entered in the section 13-0 and the data previously entered from the keyboard 6 are set.
Comparison circuit 10 compares the account number held in section 9-0 of the register. When these match, the comparator circuit 10 sends the match signal to the gate 1.
1 and turns on this gate 11. As a result, section 13- of data holding register 13
The fee held in 2 and the name of the account holder written in section 13-3 are transmitted to the display control circuit 7 via this gate 11, and are separately held in the data register 9 and sent to the display control circuit 7. The account number will be displayed on the display 8 together with the account number that has been transmitted to the account number.

The operator checks on the display 8 whether the displayed name of the account holder matches the name of the account holder written on the transfer request form in hand, and if so, presses the button on the keyboard. Press the approval key No. 6. As a result, the approval key signal "1" is transmitted to the AND gate 15, which turns on, and the account number and amount held in the data register 9 are written into the data register 16 of the terminal controller. Comparison circuit 14 then compares the account number and amount entered in data register 16 to see if they match the account number and amount set in sections 13-0 and 13-5 of data holding register 13, respectively. Ru. If they match, the match signal "1" is output to the AND gate 17, which turns on, and each data held in the data holding register 13 is transferred to the data holding register 26 of the host device via the line section 18. Fill out.

At this time, if "None" is entered in the category 26-1, that account is not a bad account as written in the bad account file 25, so gate 2
7 is turned on, and the first updating section 28 writes the transfer amount and the like into the account file 24. At this time, it is also possible to calculate the total amount of the account in the first updating section 28 and enter the total amount. Also the second
The updating unit 29 enters the fee due to this transaction in the fee file 30.

(6) Effects of the Invention As explained above, according to the present invention, the data obtained as a result of reading the account file in the host device, the calculated fees, etc. are held on the terminal side, and the data can be used to Since the data to be entered in the account file of the host device can be easily obtained, the host device does not have to recalculate the fees as in the past, and there is no need to access the defective account file again. The burden can be lightened and data processing efficiency can be improved. Furthermore, if the account file name is known, the burden of updating the account file can be further reduced by using this name. In this way, the center's in-process data can be used for the next processing, which not only improves data processing efficiency, but also ensures that the necessary data is available even if a failure occurs on the center side while updating the account file. Since it is held on the terminal side, it is also useful as a countermeasure against such failures.
