摘要： A method, system, and computer program product for optimizing query evaluation and processing services in a subscription notification system are provided. The method includes determining hierarchical relationships among a set of subscription queries received from subscription client systems. The hierarchical relationships are determined by identifying subscription queries that are subsets of corresponding other subscription queries in the set. The method also includes creating at least one subscription query at a notification source, the at least one subscription query corresponding to one or more selected subscription queries in the set and including any corresponding subsets.
