POS system data interaction method and device, computer equipment and storage medium

Abstract

The invention relates to a POS system data interaction method and device, computer equipment and a storage medium, and the method comprises the steps: obtaining a request of a POS system, so as to obtain an initial request; judging whether the initial request is a data downloading request or not; if the initial request is a data downloading request, obtaining information related to the initial request from a database to obtain initial information; processing the initial information to obtain a processing result; and feeding back the processing result to the POS system, so the POS system verifies the processing result and stores the processing result. Compared with the prior art, the POS system is not directly connected with the database, load balancing is achieved by means of an intermediate service program, then POS retail business of a larger chain scale can be supported, the higher concurrent access amount is supported, and the operation performance of the whole POS system is improved.

Description

technical field [0001] The present invention relates to a POS system, and more specifically refers to a POS system data interaction method, device, computer equipment and storage medium. Background technique [0002] The current retail POS system is implemented based on the traditional C / S framework. The store cash register generally adopts a direct connection mode to interact with the database. This architecture is characterized by simplicity, convenience, development, and maintenance, but there are also some problems that cannot The shortcomings of the solution, especially in the application of industry information such as chain stores, mother and baby stores, convenience stores, etc., its shortcomings are particularly obvious; Performance bottleneck; specifically, for customers in this type of industry, based on their operating characteristics of fat headquarters-thin stores, small stores-large chains, and high requirements for real-time data, a single database is general...

[0002] The current retail POS system is implemented based on the traditional C / S framework. The store cash register generally adopts a direct connection mode to interact with the database. This architecture is characterized by simplicity, convenience, development, and maintenance, but there are also some problems that cannot The shortcomings of the solution, especially in the application of industry information such as chain stores, mother and baby stores, convenience stores, etc., its shortcomings are particularly obvious; Performance bottleneck; specifically, for customers in this type of industry, based on their operating characteristics of fat headquarters-thin stores, small stores-large chains, and high requirements for real-time data, a single database is generally adopted, and each store is directly connected. As the scale of the chain continues to expand, the number of concurrent accesses to the database and the amount of data are also increasing, and there may be performance bottlenecks from time to time, which is specifically reflected in the slow response of the front-end sales of the POS system, or even no response for a long time, especially during peak business periods. Obviously, the POS system's front-end card is slow, which is likely to spread and affect the performance of background document entry and report query operations, resulting in the overall freeze of the POS system and affecting the user experience
