Abstract
Methods and systems for estimate derivation are described. In one embodiment, a query may be received with a predicate for sets over a collection of items. Associated samples associated with the query may be accessed. Items of an associated sample may be accessed from the collection of items. A determination of whether the predicate is an attribute-based selection from a union of at least some sets may be made. Available items of the particular associated sample may be selected from the items. Identified items may be identified among the available items in the associated sample that satisfy the predicate. An adjusted weight may be assigned to an item based on a weight of the item and a distribution of the associated samples. An estimate may be generated based on the adjusted weight of the identified items of the associated samples that satisfy the predicate. Additional methods and systems are disclosed.
