DDBuilder: What is a Typedef? (Superseded)
DDBuilder has been superseded by the BASIS DBMS Data Dictionary module accessible from the BASIS IDE or the Enterprise Manager. Recommended for usage with ODBC/JDBC access to PRO/5, Visual PRO/5, BBj application data. DDBuilder is no longer included in the BBj download package as of version 12.0 but can be downloaded with Visual PRO/5.
