Hot tuples within a database are detected. The hot tuples are within a selected table having a number of columns over which tuples are stored. The hot tuples are thus included within the tuples stored in the selected table, and are defined as the tuples that are frequently referenced by tuples of one or more other tables. Such hot tuples may be detected without regards to select conditions placed on them via queries of query templates. Detection of the hot tuples is based on the query templates of such queries that are processed against the database, which includes the selected table and the other tables referencing the selected table. The database is stored on a non-volatile storage. The hot tuples detected are stored or placed to provide for quicker access thereof.
