Synchronization can be used in a special database synchronization tool, expensiveSynchronization can also write their own applications, generally there are two ways, one is all data synchronization, each time all synchronization, is suitable for the table data is less, such as code table
One is according to the timestamp to synchronize, such as increased on the table last modified time, according to the last synchronization time, after the modification of data synchronization to the server

1> This architecture involves database synchronization problems, you can refer to some means in sinopec gas station national wide synchronous data, a few years ago, Sybase do more mature, the other is not reliable, can check online,2> Low cost solution or use PB C/S multilayer, database on the remote end, the Internet, online there are many case studies, I also used, although cumbersome, but can also be used,
CodePudding user response:
Generally by the timestamp synchronization, make before, packaged into XML, client according to the time written to the database server solution package, send and receive data in the form of mail,
