Each driver provider will have their own version numbering system for their driver versions, which will likely be different from the ODBC version number it implements.The ODBC version 3 specification was introduced in 1995, so it is likely your database provider has a driver that implements this level of compliance.But you might be working with a database that Tableau doesn't have a connection for.
Tableau has tested ODBC connections with many data sources, but due to the volume of ODBC drivers available on the market we haven't tested against every possible driver, nor can Tableau perform this breadth of testing.
Tableau supports the ability to customize your ODBC data connection, which can improve the connection experience.

The ODBC driver, usually provided by the database vendor, accepts requests in this standard syntax and converts the request to the native format that the target database prefers.
In effect, the ODBC driver is a translation layer to convert from a general-purpose request to the database-specific request.
