comment on TABLE ACS_PRIVILEGE_HIERARCHY is '
  To reduce number of permission records, and to simplify permission
queries and associated business logic in Java layer, this table stores
privilege hierarchy.  This hierarchy allows child nodes to have multiple
parents, and parents to have multiple children.
  This table stores only direct (parent,child) mappings, which is often
referred as adjacency model, resulting in small table.
