Data update method of wholesale terminal, wholesale terminal and system and storage medium

Abstract

The invention discloses a data updating method of a wholesale terminal, a system, and a storage medium. The wholesale terminal has a local small database for storing transaction data. The method comprises the following steps: S1, when the transaction data of the local small database needs to be updated, acquiring the hardware utilization rate of the wholesale terminal and judging whether the hardware utilization rate exceeds a preset threshold value; S2, if not, storing the transaction data to be updated one by one on the new storage location according to the time order of each transaction data; S3, if yes, the updated transaction data is overwritten with the oldest transaction data in chronological order. The method can judge whether the old data need to be covered according to the hardware usage of the wholesale terminal when the data is updated, so as to ensure the operation efficiency of the wholesale terminal and avoid the phenomenon that the wholesale terminal is stuck due to theexcessive storage quantity.

Description

technical field [0001] The present invention relates to the technical field of data updating, and in particular to a data updating method for a wholesale terminal, a wholesale terminal, a system and a storage medium. Background technique [0002] Existing electronic devices, such as mobile phones, tablet computers, etc., will store the received data in the memory when updating data, and will not inform the user that the capacity of the memory is full and cannot be stored until the capacity of the memory is full. If the memory stores too much data, it will affect the running speed of the electronic equipment, causing the electronic equipment to run slowly, and the phenomenon of jamming often occurs. For some wholesalers, they usually need to use electronic devices to store transaction data in order to view and verify transaction orders. Over time, the amount of transaction data is very large. In this case, the existing electronic device data update method will easily cause t...
