  • Patent number: 8745038
    Abstract: Computer-based methods, computer-readable storage media and computer systems are provided for optimizing integration flow plans. An initial integration flow plan, one or more objectives and/or an objective function related to the one or more objectives may be received as input. A computing cost of the initial integration flow plan may be compared with the objective function. Using one or more heuristics, a set of close-to-optimal integration flow plans may be identified from all possible integration flow plans that are functionally equivalent to the initial integration flow plan. A close-to-optimal integration flow plan with a lowest computing cost may be selected from the set as a replacement for the initial integration flow plan.

  • Patent number: 8719769
    Abstract: A method for quality objective-based ETL pipeline optimization is provided. An improvement objective is obtained from user input into a computing system. The improvement objective represents a priority optimization desired by a user for improved ETL flows for an application designed to run in memory of the computing system. An ETL flow is created in the memory of the computing system. The ETL flow is restructured for flow optimization with a processor of the computing system. The flow restructuring is based on the improvement objective. Flow restructuring can include application of flow rewriting optimization or application of an algebraic rewriting optimization. The optimized ETL flow is stored as executable code on a computer readable storage medium.

  • Publication number: 20140039782
    Abstract: Systems and methods are provided for determining an impact of a planned event. Traffic flow velocity is measured at each of a plurality of traffic sensors over a period of time before the planned event, with each traffic sensor having an associated geographical location. A plurality of measured traffic flow velocities for each traffic sensor are stored on a non-transitory computer readable medium. A traffic flow velocity at each traffic sensor is measured at each of a plurality of representative times within a defined time period including a known start time and an expected end time of the event. A threshold velocity is calculated from the stored traffic flow velocities for each traffic sensor corresponding to each representative time. For each representative time, a set of traffic sensors is determined at which the measured traffic flow velocity during the defined time period is less than the threshold velocity.
