Here is another version of the Teradata DD/DS structure to make available to developers, etc. :

     REPLACE RECURSIVE VIEW dbadmin.DBC_Hierarchy
     (
        DatabasePath
       ,DatabaseName
       ,LevelNbr
       ,ExtendedDatabaseName
       ,DatabaseType
     )
     AS
     (
       SELECT
               CAST(TRIM(DatabaseName) AS VARCHAR(512))   AS DatabasePath
               ,DatabaseNameI                             AS DatabaseName
               ,CAST(0 AS INTEGER)                        AS LevelNbr
               ,CAST(TRIM(DatabaseName) AS VARCHAR(50))   AS ExtendedDatabaseName
               ,RowType                                   AS DatabaseType
       FROM
               DBC.DBase
       WHERE
               DatabaseID = OwnerID
       UNION ALL
       SELECT
               DS.DatabasePath
               || '.'
               || TRIM(DB.DatabaseName)
               ,DB.DatabaseNameI
               ,DS.LevelNbr + 1
               ,SUBSTR('....................', 1, DS.LevelNbr)
               || TRIM(DB.DatabaseName)
               ,DB.RowType
       FROM
               DBC_Hierarchy DS
               INNER JOIN
               DBC.DBASE DB
                       ON DS.DatabaseName = DB.OwnerName
                          AND
                          DatabaseID <> OwnerID
     );
