Abstract: The current invention can provide methods and systems for creating and referencing data mapping requirements in a highly efficient, effective manner by providing functionality needed at the beginning, ending, and throughout the life of a data warehousing project. This can be accomplished through the ability to: prioritize fields of interest, provide visualization of the data mapping, set the ETL rules, provide progress and filtering functionality based on current status, provide learned intelligent tips for the next needed functionality, provide source comparisons per applied learning, apply learning for product enhancement, provide data profiling, provide data lineage, and have all of this functionality work together to achieve these capabilities.
