Excuse me what's the solution-CodePudding

We now have a application, first using the front-end equipment read data on the front-end equipment, then summary data for processing,
Feeling was prepared using master-slave database configuration, but can't take on so much equipment about 50 sets of front-end equipment (early) and configuration seems to be more difficult, is there any solution?

CodePudding user response:

Feel like is to get the data synchronization to the master database in the front-end CLIENT, this is generally used in local use SQLITE store, and then upload, synchronized to the master database,

Front-end data is others give me it's already existing mysql database, I now side summary data processing data table is the same, this situation could you please tell me what is the solution?

Master-slave database is not used in this scenario,
Your application is a typical application of collection and processing,
See you instructions, sampling data is placed on equipment database, can be applied to the central server to do a, access to various data acquisition equipment, stored in a central database,
Does not want to know if the center collection device, can do an application in acquisition equipment, upload the data to a central database, if there is excessive collection devices, need to consider the concurrent processing, may need to do a service application in a central server, receiving the application of data,

Collect data to to the rightness, the center server can know what probably need to use this technology, please? I go to learn, I really don't understand this, thank you

Can consider to do with Java, do a Java application, use JDBC to connect to the database, using SQL database operation,

Ok just a little idea too. Thank you
