  • Classification and sequencing of mixed data flows
    Patent number: 7739267
    Abstract: A computer implemented method for processing a mixed data flow. Mixed data flow operators are classified. The mixed data flow operators are associated with multiple runtime environments in which the mixed data flow operators can be executed. The mixed data flow operators are segregated into regions. A mixed data flow operator in a particular region is executable by one of the multiple runtime environments associated with the particular region. The execution of the regions is sequenced.

  • Dilation of sub-flow operators in a data flow
    Patent number: 7689576
    Abstract: A method for dilating a sub-flow operator in a data flow is provided. The data flow is traversed to locate sub-flow operators. The data flow bound to a sub-flow operator is retrieved. The sub-flow operators are then injected into the data flow.

  • Data flow system and method for heterogeneous data integration environments
    Patent number: 7689582
    Abstract: A computer implemented method, apparatus, and computer usable program code for generating an execution plan graph from a data flow. A metadata representation of the data flow is generated in response to receiving the data flow. A set of code units is generated from the metadata representation. Each code unit in the set of code units is executable on multiple different types of runtime engines. The set of code units is processed to produce the execution plan graph.
