Query by example for nested tables
QBEN, a Query By Example language for Nested tables, is described. QBEN is user-friendly and allows for the easy formulation of complex queries. At the same time, optimization techniques can be incorporated that enable the global optimization of a series of queries. QBEN is addressed both to non-experts and experts. Comparison with other approaches is also made.
