Abstract: Reducing data access resources by creating a scoring mechanism for computing a running score for data objects in a database having an associated score value in order to determine whether or not a set of data object(s) should remain in a caching gateway or whether or not the set of data object(s) should be removed from the caching gateway.

Abstract: An approach is provided in which the approach receives a query request to execute a query. The approach provides multiple query execution options based on multiple hardware configurations. The multiple query execution options include multiple execution times and multiple execution costs. The approach receives a selection that selects at least one of the query execution options and, in turn, executes the query on at least one of the hardware configurations based on the received selection.

Abstract: A method and system is presented to reduce the number of copies in the execution of routines written in a procedural language with by-value assignment semantics. During routine compilation, each statement within the routine is classified as being copy-sensitive or not, depending on the operations it contains. During routine execution, a lazy copy strategy is used to determine when variables should be copied: copies are not performed on variable assignment, but instead are delayed until variables are used in copy-sensitive statements. If a variable is never used in a copy-sensitive statement, then it will never be copied, thus saving computation time and storage.
