Type Three Driver

A net-protocol fully Java-enabled driver translates JDBC API calls into a DBMS-independent net protocol which is then translated to a DBMS protocol by a server. This net server middleware is able to connect all of its Java technology-based clients to many different databases. Many mainframe legacy non-relational databases use this kind of driver.

Advantages for using this type of driver include the following:

• Allows access to almost any database since the databases ODBC drivers are readily available

• Offers significantly better performance than the JDBC/ODBC Bridge and Type 2 Drivers

• Advanced Java feature set

• Scalable

• Caching

• Advanced system administration

• Does not require applicable database client libraries

The disadvantage for using this type of driver is that it requires a separate JDBC middleware server to translate specific native-connectivity interface.
