  • Systems and methods for correlating errors to processing steps and data records to facilitate understanding of errors
    Patent number: 11144377
    Abstract: A computer program file or a sequence of processing steps from an authoring environment of a data processing system is used to generate a graph including nodes representing the processing steps is generated. Unique identifiers (tags) are assigned to the nodes. One or more processing steps are optionally modified while preserving the original identifiers. If an error occurs during execution, error information is saved including the processing step that failed and data records that triggered the failure. The identifier of the failed processing step is attached to the error information. The error information is collected and processed. The collected error information is used to correlate the error to the failed processing step and to data records triggering the error using the identifier of the failed processing step recorded with the error information. The correlated error information indicates cause and location of the error.

  • DISCOVERY AND USE OF NAVIGATIONAL RELATIONSHIPS IN TABULAR DATA
    Publication number: 20140136511
    Abstract: Detection and use of relationships in tabular data is enhanced. A foreign-key-based relationship between two tables in memory is automatically discovered by a module. A view over table data is computationally augmented by adding an expandable hierarchical column. The expandable hierarchical column includes second table data that is related to rows of a first table by the discovered foreign-key-based relationship. A naming scheme for the added column is described. Sometimes the augmentation places an AddJoinColumn operator in a query expression tree; sometimes the tree is rewritten by moving a query operator or replacing a specified pattern of operators by a flat Join operation between two tables. Column expansion may be followed by reshaping data into a flat table, by getting a homogeneous query, by performing a join, or other operations.

  • Flexibly transferring typed application data
    Patent number: 8296354
    Abstract: The present invention extends to using Simple Object Access Protocol (“SOAP”) to exchange typed objects, such as, for example, parameters for invoking methods. A computer system accesses typed object parameters corresponding to a typed object. The typed object is annotated with one or more message contract attributes of a message contract model defining a mapping between typed object parameters and corresponding SOAP elements. The computer system utilizes the message contract attributes to map the typed object parameters into a SOAP element and inserts the SOAP element into a SOAP envelope. A receiving computer system accessing the SOAP element and utilizes the message contract attributes to map the SOAP element back into the typed object parameters.

    Patent number: 7916817
    Abstract: A method for reducing interference from at least one narrowband interferer in a pilot symbol assisted receiver (10) includes the steps of; receiving a stream of received data, passing the stream of received data through an adaptive filter that reduces interference from any narrowband interferer, passing the filtered data through a correlator (7, 8) arranged to detect pilot symbols, when a pilot symbol is detected passing the stream of received data to a receiving apparatus without first passing the received data through the adaptive filter (3), and wherein the pilot symbol includes one or more repetitions of known data or pseudo noise.
