I had a nice week playing with the Mahout CF Libray and its MySQLJDBCDataModel to get the input data from a database. But then this idea occurred to me. I have another sever with similar data sets, which is running another database server, Oracle, namely.
I'm wondering how I can combine these two to get the input data for my recommender engine. Do, I start by implementing the the JDBCDataModel or ? I appreciate any insight you might have for this?
