1. A system for scheduling database operations on at least one database, the system comprising:

  • a first global-results processing matrix having a plurality of interconnected processing nodes operating in parallel and being adapted to execute an executable on the at least one database, the executable being representative of a query having at least one database operation;

    a first query agent operably connected to the first global-results processing matrix and being adapted to manage the execution of the executable by the first global-results processing matrix; and

    a scheduling services module operably connected to the query agent and the first global-results processing matrix and being adapted to;

    schedule a time for execution of the executable by the first global-results processing matrix; and

    direct the first query agent to submit the executable to the first global-results processing matrix for execution at the scheduled time of execution.
