Are you sure about that? I believe RDB originally stood for "relational database".

From http://www.oracle.com/rdb/

"Oracle Rdb is a full-featured, relational database management system for mission-critical applications on OpenVMS platforms.

<misc stuff deleted>

The Oracle Rdb family of products also includes Oracle CODASYL DBMS (a network data model database system), Oracle CDD/Repository (for managing meta data), and Oracle Trace."

Were you thinking CODASYL as above? Even that is not an hierarchical database!
