[rules-users] Drools + ETL Process

Hi all, I am using Drools 5.0 with Tomcat 6 and MySQL. Now I need to insert data in the drools database but I DON'T want to use the Guvnor interface. This is because in the future we'll need to use a kind of ETL process to populate the drools database. Should I create a java class with JDBC access and perform a SQL direct to that tables? I did the reverse engineering of the drools database but I could not understood yet where the data are persisted. Any advice should be very helpful. Thanks in advance.
