We consider the problem of learning a record matching package (classifier) in an active learning setting. In active learning, the learning algorithm picks the set of examples to ...
In this paper we propose a new operator for advanced exploration of large multidimensional databases. The proposed operator can automatically generalize from a specific problem c...
The query execution engine in Microsoft SQL Server employs hash-based algorithms for inner and outer joins, semi-joins, set operations (such as intersection), grouping, and duplic...
In this paper we describe novel techniques that make it possible to build an industrial-strength tool for automating the choice of indexes in the physical design of a SQL database...
A frequent dilemma in the design of a database programming language is the choice between a language with a rich set of tailored notations for schema definitions, query expression...
