Data Preparation User Interface for Aggregate Comparison of Datasets at Different Nodes in a Process Flow

摘要

A method compares data sets in a data preparation application. The method displays a user interface including a flow diagram having a plurality of nodes. Each of the nodes corresponds to a data set having a plurality of data fields. A user selects two nodes from the flow diagram. In response to the user selection, the method forms a composite data set comprising a union of two data sets corresponding to the two nodes and groups data values for each of a plurality of data fields in the composite data set to form a respective set of bins. The method then displays distributions of data values for the plurality of data fields in the composite data set. Each distribution comprises the respective set of bins for a respective data field. Each displayed bin depicts counts of data values in the respective bin originating from each of the two data sets.
