Example Embodiment
[0040] Such as figure 1 Shown is a schematic diagram of each component module of the database fault automatic detection and transfer system of the present invention, which includes a user terminal 100, a cache (Cache) server 200, a database master (Master) server 300, and a database slave (Slave) server 400 , And the management end 500. The database server of the present invention adopts the dual redundancy structure of Master / Slave, and at the same time, multiple slave servers can be configured, and the data between the databases is strictly synchronized to ensure that the data of the Master server and the slave server are consistent. In addition, the cache server 200 of the present invention is directly connected to a plurality of independent client terminals 100 through the Internet, and performs data transmission; then, the related data of the client terminal passes through the cache server 200, and performs data transfer with the database server (300, 400). Synchronization...
