Abstract
The invention relates to a computer system and a corresponding method and a corresponding computer-readable medium. The computer system is suitable for determining the result of a join. Based on the access pattern of an application, the computer system infers that a particular subjoin is empty. The computer system then excludes the inferred-empty subjoin when performing the join, performing a more efficient and faster database join operation.
