Transaction certificate management method, data processing system and computer storage medium

Abstract

The embodiment of the invention discloses a transaction voucher management method, a data processing system and a computer storage medium, which are used for solving the problem that the generation time of a transaction voucher is prolonged because the data processing system needs to process a large amount of data. The method provided by the embodiment of the invention comprises the steps that thedata processing system predicts according to a prediction algorithm to obtain n transaction voucher demanded quantities of the next peak period of the current time point; controlling the number of the identification information stored in the cache of the data processing system to be at least n; after receiving each identification information request sent by a terminal, calling one piece of target identification information from the at least n pieces of identification information stored in the cache, therefore, the data processing system does not need to access the database repeatedly when processing a plurality of identification information requests, but directly obtains the identification information from the cache, so that the processing data volume of the database is reduced, the obtaining speed of the target identification information is greatly improved, and the waiting time of the terminal is shortened.

Description

technical field [0001] The embodiments of the present application relate to the field of data processing, and in particular to a transaction voucher management method, a data processing system, and a computer storage medium. Background technique [0002] Data processing systems are used in the daily operation of catering stores. For example, the data processing system is used to manage the financial data of the store, and to generate consumption receipts or stored value receipts when customers consume or store value for consumer cards. Catering outlets use a point of sale information system (point of sale, POS) to generate receipts. During the process of the POS system generating the documents, the POS system calls the application programming interface (application programming interface, API) of the database of the data processing system, obtains the identification information of the documents from the database, and then generates the corresponding documents. The identifica...
