Compare values from two different database: MySQL and Oracle

Question

Hi, I am working on a project that I have to write an application using c# to compare data from two databases. One of the database is MySQL and the other is Oracle.

I know that I can use ODBC to establish separate connections with the two databases, but what is the best way to compare the values from two database connection? Is there something as simple as this? I am a beginner in writing c#.

 if (DatabaseA.column1 = DatabaseB.column1) then
     do this;
end if;

Hope to hear from you, thanks!
