hierarchy - mysql db with parent child relation -
Can anyone help me with an Art Design?
Confirmation of the problem I have many local DBs with data that is now populated. Now this data needs to be collected in Central DB for further processing.
Like it is a parent and many children, the child does not have to coordinate with the parents, but parents have to take data from the child for further processing.
I am using mysql db Is there a tool that can help me?
This is the addition of my child's DB to a different server and my parents are DB on a different server
- Set the engine of all tables as 'INNODB'
- set foreign keys
