You can use an evaluation copy of Omnis Studio to copy the data from the Omnis data file into a MySQL database. Using the SQL Browser utility, you create an OMNISSQL session that connects to the data file (.DF1) and a MYSQL session that connects to your MySQL database. Open both sessions. You can then use drag and drop to copy whole tables directly over to MySQL. If you want continued access to MySQL after the trial period expires, it will require a standard developer license I believe.
