Set hierarchies

Reference data set hierarchies within InfoSphere® MDM Reference Data Management Hub are tree-style hierarchy structures that are created over the values within a reference data set. Use the Hierarchy view to access the hierarchies.

Actions available from the Hierarchy view include:
  • Save or discard changes to a hierarchy.
  • Select the hierarchy to work on by selecting the Hierarchy tab from the Set Editor.
  • Create a new empty or pre-populated hierarchy over the values in a reference data set, as described in Creating set hierarchies.
  • Import a hierarchy definition from a comma-separated values (CSV) file, as described in Importing set hierarchies.

    A hierarchy structure can be defined between the elements of a set in a CSV file and imported over a set of reference data values. When you work with hierarchies over a large set of values, define the hierarchy externally and then create a CSV file to import the hierarchy into InfoSphere MDM Reference Data Management Hub.

  • Copy a hierarchy.
  • Delete a hierarchy.
  • Refresh the list of hierarchies.
Note: Each reference value can exist only once within a hierarchy.
