Hence, this kind of driver is generally most appropriate when automatic installation and downloading of a Java technology application is not important. A native-API partly Java technology-enabled driver converts JDBC calls into calls on the client API for Oracle, Sybase, Informix, DB2, or other DBMS. Note that, like the bridge driver, this style of driver requires that some binary code be loaded on each client machine. The specific protocol used depends on the vendor.
In general, this is the most flexible JDBC API alternative. A native-protocol fully Java technology-enabled driver converts JDBC technology calls into the network protocol used by DBMSs directly.
