  • Compression of timing data of database systems and environments
    Patent number: 10019465
    Abstract: Timing data associated with a database or database system can be stored in a reduced or compressed form which can be decompressed back to a full or original form. In doing so, timing data can be compressed by using a subset of a full set of possible values (e.g., a determined range which is more likely to occur) instead of using a full set of possible values. Timing data can also be compressed by eliminating redundant, insignificant duplicate and/or common values, for example, between one or more components (e.g., start and end times of a period of time) of the timing data.
    Type: Grant

  • System, method, and computer-readable medium for costing user-defined functions and methods in a database management system
    Patent number: 9996580
    Abstract: A system, method, and computer-readable medium for the calculation of execution time estimates of user defined functions/user defined methods are provided. The execution of a UDF or UDM is timed several times at the time of the UDF/UDM creation, and an average execution time of the UDF/UDM is obtained. The resulting average execution time is then stored in a data dictionary where the optimizer may consult this value to factor it into the cost of execution of a query.
