Summary Data Lineage

Summary Data Lineage

When you view a data lineage diagram, Metadata Manager displays a summarized view of the diagram as HTML 5. The summary view hides certain resources and also hides transformation logic within PowerCenter mappings. To view all resources and all transformation logic, you can switch from the summary view to the detail view through the task bar.
The summary view hides the following objects in the data lineage diagram:
  • All resources for which the
    Hide in Summary Lineage
    option is enabled in the resource configuration properties.
  • All transformations and transformation instances within PowerCenter mappings that do not provide input or output for the mapping.
The summary view has the following advantages:
Reduces the complexity of the data lineage diagram.
The summary view reduces the complexity of the data lineage diagram when you do not need to view objects such as transformations within a PowerCenter mapping or intermediate staging databases. For example, you run data lineage analysis on a business intelligence report to see where the column data originates from. In this case, you are not interested in seeing the PowerCenter mappings that transform the source data or the intermediate staging tables. The summary view can hide these objects from the data flow.
Reduces the amount of time it takes for Metadata Manager to generate the data lineage diagram.
PowerCenter mappings and mapplets can include hundreds of transformations and staging tables. Generating a data lineage diagram that includes hundreds of transformations and staging tables can take several minutes. Generating the diagram without the staging tables or transformation details takes less time.
