To assist users in database exploration, we present the YmalDB system, a database system enhanced with a recommendation functionality. Along with the results of each user query, YmalDB computes and presents to the users additional results, called Ymal (i.e., "You May Also Like") results, that are highly related with the results of their original query. Such results are computed using the most interesting sets of attribute values, called faSets, that appear either in the results of the original query or in the results of an appropriately expanded one. The interestingness of a faSet is based on its frequency both in the query result and in the database.
