Is it possible to connect to multiple databases simultaneously?Using single statement can one update or extract data from multiple databases
Answers
Yes, it is possible but it depends upon the capabilities of the specific driver implementation, we can connect to multiple databases at the same time. We doing following steps:

• Minimum one driver will be used to handle the commits transaction for multiple connections.
• To update and extract data from the different database we use single statement for this we need special middleware to deal with multiple databases in a single statement or to effectively treat them as one database.   Your Comment
