Thus, the following detailed description of the embodiments of the present application, as provided in the accompanying drawings, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, are intended to be within the scope of the present application.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures.

Referring to fig. 1, fig. 1 is a flowchart of a data synchronization method according to some embodiments of the present application. The data synchronization method is applied to first terminal equipment, and the first terminal equipment is used for receiving data to be synchronized in the second terminal equipment. The method comprises the following steps:
s101, acquiring encrypted data transmitted by a second terminal device, wherein the encrypted data is generated by encrypting data to be synchronized by the second terminal device through a preset encryption algorithm.
S102, decrypting the encrypted data according to a decryption algorithm corresponding to the encryption algorithm to obtain data to be synchronized and model names corresponding to the data to be synchronized.
S103, configuring a preset loading script according to the model name.
S104, configuring a timing task in the crontab by adopting the configured preset loading script so as to load the data to be synchronized.
In step S101, before data transmission, the first terminal device configures a mode of the data to be synchronized, and a model name is consistent with a type of the data to be synchronized. The second terminal device encrypts the data to be synchronized by adopting a preset encryption algorithm to obtain encrypted data, wherein the encrypted data can be symmetrically encrypted or asymmetrically encrypted. The second terminal device may transmit the encrypted data in sftp.
In this step S102, if the second terminal device adopts a symmetric encryption algorithm, the first terminal device may decrypt with the corresponding key. And when the second terminal equipment encrypts the data to be synchronized, the model names corresponding to the data to be synchronized are also encrypted together, and the encrypted data are transmitted to the second terminal equipment together. The model name may be set in the forefront of the encrypted data, that is, in the data decrypted by the encrypted data, and the previous predetermined number of data segments is the model name.
In step S103, different types of data to be synchronized correspondingly use different preset loading scripts, so that data loading efficiency can be improved. Because different types of data to be synchronized have different model names, parameter configuration can be directly performed on the preset loading script according to the model names.

When data to be synchronized is loaded in an unix environment, if the database is an oracle database, adopting an sqlldr function as a target data import function; if the database is a mysql database, a mysql-h function is used as a target data import function. The script is configured, the code coupling is reduced, different points of the program are obtained by configuration, the effect of synchronizing data can be newly added by configuring the model name, the development efficiency is improved, the cost is reduced, and the maintenance is convenient.
Optionally, in the data synchronization method of the embodiment of the present application, when the data to be synchronized is loaded, the preset loading script is executed in series or concurrently.
In some embodiments, when the loading of the data to be synchronized is performed, the loading condition of the data is monitored, and when abnormal loading of the data is monitored, reminding information is generated. The abnormal situation is processed in time, so that the data is ensured to be loaded in time, and the influence on the service is avoided.
