1. A computer-implemented method, the method including:

  • receiving data lineage information for multiple components representing at least two logical datasets and a transformation, with the data lineage information identifying a first logical dataset from which the transformation is to receive data and a second logical data dataset to which transformed data is to be provided, the transformation represented by a component in the data lineage information including one or more rules to be applied to data from the first logical dataset, and with the data lineage information identifying paths and flow traces of data though the multiple components;

    receiving data specifying one or more proposed changes to a field in the first logical dataset, a field in the second logical dataset, or the transformation;

    analyzing the multiple components according to the data lineage information to identify each component affected by the one or more proposed changes;

    for at least one identified component identified as affected by the one or more proposed changes,generating an impact metric representing a number of times a field specified by the one or more proposed changes is referenced within the at least one identified component;

    determining, based on the generated impact metric, an impact of implementing the one or more proposed changes to one or more of the multiple components; and

    storing information about the impact metric.
