Tag Historian v/s SQL Bridge

Please guide me about Tag Historian module v/s SQL Bridge module.

Where did I get the detail documentation about the Tag Historian?

I have license for Tag historian module and I want to use “Transaction group” to log the data to MySQL Database.

Which transaction group I can use?

Stored Procedure

You will have to buy the sql bridge module to use the transaction groups. You may also look at using tag change scripts or timer scripts to accomplish your task in the gateway event scripts section of the designer.
