Hello, I would like some advice, now I have these tables in MYSQL :
User_subject user_id, subject_id, relevance Item_subject item_id, subject_id I would like some advice to have some recommendations. Now, to compute the user similarity, I made a JDBCDataModel for the table User_subject. To compute the item similarity, I made the same, for the table item_subject. Now, I have my similarity between users, and between items. Do I need to make a table like that : user_item user_id, item_id, relevance I will have millions of rows, and I think it could be very slow no ?
