A hierarchical schema is an asset that defines the expected hierarchy of data. The schema is based on an XML sample file or XSD schema file that you upload in Data Integration.
You can use a hierarchical schema in a Hierarchy Builder transformation or a Hierarchy Parser transformation. You can create the hierarchical schema as a standalone asset or within the transformation. Whether you create the schema as a standalone asset or within a transformation, you can associate it with any transformation.
After you create a hierarchical schema, you can edit it to change the root or the schema definition. You can't edit or delete a hierarchical schema if it's used in a transformation. You can also update an existing XSD schema file or XML sample file to reflect new or modified changes.
