Application scenario is:
1. The company headquarters in Beijing have a server, the server database to keep the equipment information across all branches, everywhere around the branch also has a server and server to save all data to eliminate institutions, all of the local agency also has a server for retention of in-house server,
2. In the Beijing headquarters of the server to add branch after the information about the device or its local offices to timely delivery to the corresponding branch or local agency database,
3. In local agency to add database should be timely to the superior agency push, until delivery to Beijing headquarters,
Dozen principle is superior to save all the children of equipment information, superior to the child the server data step by step to push to the corresponding level,
With oracle database, consult should what technology is used to implement this requirement?

CodePudding user response:

Nobody reason I, everyone look bai

CodePudding user response:

Try using oracle flow replication

CodePudding user response:

See your needs, is to want to use the DB and communications between the DB implementation, or with the aid of additional application implementation,
Also, the frequency of the data synchronization cycle, real time, or the timing,
