As more and more information from autonomous databases becomes available to lay users, query processing over these databases must adapt to deal with the imprecise nature of user queries as well as incompleteness in the data due to missing attribute values (aka “null values”). In such scenarios, the query processor begins to acquire the role of a recommender system. Specifically, in addition to ...
