Abstract: A method of summarizing data includes providing a multi-method summarization program including instructions for summarizing data for a transaction processing system. At least one functional aspect of the transaction processing system for which a summarization of a subset of the data is desired is determined. The functional subset to a user as a light summarization program is exposed. The dependencies of the functional subset can be enforced at runtime allowing packaging flexibility. A method for efficient parallel processing involving not necessarily filled requests for help.
