The two types of systems are usually developed by different companies, the deployment modes are different, the educational administration system is generally deployed in the local of a school, and the educational administration system is generally deployed in the cloud. The two systems need high-frequency data synchronization, for example, teacher lesson information and student lesson selection information in the educational administration system need to be synchronized to the educational administration system, and the achievements generated in the educational administration system need to be synchronized to the educational administration system. After the student selects a class, the student often needs to start learning immediately, so that the requirement on synchronization instantaneity is high. After the result is obtained, the sensitive information can be neither easily leaked nor subjected to any error, so that high requirements are also placed on the safety and accuracy of synchronization. Before this, data is exported from system a and then imported into system B usually in an excel table manner. Due to the data format differences between systems, the data exported by system a cannot be directly used, and must be manually adjusted to a format acceptable to system B for successful import. The method is time-consuming and labor-consuming, cannot ensure real-time updating of data, has the risk of information leakage, and is very easy to make mistakes. And the system A updates the data of the system B in real time when the data are changed. However, the use of this scheme means that the systems from two companies can directly call the interface of the other side, and the security of the interface and data cannot be guaranteed. In addition, due to the lack of backup of data, in case of errors in transmission, the source of the data cannot be traced back, and the accuracy of the data cannot be guaranteed.
