Picking adequate samples for approximate decision support queries using inverse SRSWOR

A simple random sample of records from a large data warehouse may not contain sufficient number of records that satisfy highly selective queries. Efficient sampling schemes for such queries involve using innovative techniques that can access records that are relevant to specific queries. In drawing...
