I need to do data mining on the multiple database. I have one database in oracle on one machine, one databse in Access, one in SQL server.
I want that I should apply association rules for data mining just once on all the database and it do the mining. For that I have to tranfer the data from different database to one database on which the mining rules will operate and we feel that we are doing mining on multiple databases simultaneosly.

Please provide me the way to tranfer the data from one database to other. ( Please be specific and also provide the script/code)
