This driver is known as a native API driver. This driver receives the calls from Java application and converts them in to vender specific native API calls. Here, we need to install The vendor-specific driver on the client machines.

If we change the Database, we have to change the native API, as it is specific to a database and they are mostly obsolete now, but you may realize some speed increase with a Type 2 driver because it eliminates ODBC's overhead.
