System and method for the derivation and application of sub-iteration contexts in a transformation operation in a data integration system

摘要

Methods and systems for improving a data transformation operation that converts a source data instance containing repeating elements into a target data instance having a user-specified structure, based solely on a user's specification of a target template. The methods and systems derive and calculate sub-iteration contexts by applying a selected heuristic to the source data instance and the target template, and use these sub-iteration contexts to create a target data instance having a repeating structure that agrees with the user-specified target template. The methods and systems can be customized by the selection of heuristic, and by the specification of explicit sub-iteration contexts that may override the derived contexts.
