Problems solved by technology

This method can improve the efficiency of execution, but the pressure to update hot data is not reduced. The update of hot data is still hot, and the operation of reading hot data will be affected, and the data will not be completed in time if the concurrency is high. update
In addition, the asynchronous calling method may cause data loss problems when the server crashes

Abstract

The invention provides a data updating method, which comprises the following steps of: 102, storing increment data generated by operating specified data in an original table in a temporary storage table respectively; and 104, updating values of the specified data in the original table according to the increment data. The invention also provides a data updating device. By the technical scheme of the invention, data can be updated in time under the condition of generating high concurrent operation, the running efficiency of a system is improved, and the data of the system is consistent and safe and is not lost.

Description

technical field [0001] The invention relates to a data update method in an application system, in particular to a data update method and device. Background technique [0002] There is a type of data in the application system that is obtained by summarizing other data, such as the account balance in the enterprise, the number of remaining commodities in the inventory, etc. In high-concurrency network applications, this data is often modified due to the transaction. [0003] The current application system mainly has the following methods to solve this problem: [0004] 1) Use database transactions to maintain data update consistency. Each transaction updates the hotspot data through SQL directly according to the incremental update, using the database transaction characteristics to ensure the mutual exclusion of updates and the consistency of data updates. The problem with this method is that if a large number of concurrent businesses request to update the same piece of data ...
