DUALITY JDBC Proxy
Type 3 JDBC driver which functions as a proxy for any other JDBC driver. DUALITY employs a reversed connection scheme, such that connections may be established through firewalls without requiring any openings for inbound connections. All features of the JDBC API are implemented, including streamed data types. Replace the JDBC driver in your application with the DUALITY Driver and install the DUALITY Server behind your firewall.
