Document number generating method and document number generating system

Abstract

An embodiment of the invention provides a document number generating method and a document number generating system. The method includes the steps: determining business numbers according to received system instructions; selecting unused serial numbers as sequence numbers from serial numbers corresponding to the business numbers; determining designated information at the tail of document numbers; generating check bits by means of computing according to the business numbers, the sequence numbers and the designated information; and assembling the business numbers, the sequence numbers, the check bits and the designated information according to preset assembly rules to generate the document numbers. By the aid of the data processing method, the document numbers including the designated information can be obtained by means of computing once, response time for generating the needed document numbers is strictly controlled, and system overhead is effectively controlled.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and system for generating a voucher number. Background technique [0002] Existing credential numbers, such as the credential numbers generated by the banking system, usually include three components: a fixed-digit part with a specific meaning, that is, a business number, a fixed-digit sequential number part, and a fixed-digit checksum bit part. Among them, the business number can be assigned according to the type of customer, the customer's location, etc., and the sequential number is used to ensure that the voucher numbers of the same business number are not repeated, and the check digit is calculated based on the business number and the serial number. [0003] In the prior art, the check digit is located at the back end of the voucher number. The generation process of the voucher number is to calculate and determine the check digit after determining the busin...

AI Technical Summary

Problems solved by technology

It can be seen that according to the above method, the above data processing process needs to be repeated many times to obtain the credential number with one of the specific last digits. The system overhead is uncontrollable, and the response time is uncontrollable. For a large transaction volume system that requires real-time response, the system may fail. risks of
