Why is JDBC performance less?
The performance of this driver is less because the JDBC calls go through the bridge driver to the ODBC driver and then to the native database connectivity library. The result comes back through the reverse process. That means in simple words we can say bad performance due to two-layer translation.
What is type 4 JDBC?

What is a driver in Java?
The driver is an interface that existed between Java application and database to map Java API calls to Query language API calls and Query language API calls to Java API calls. To provide driver as a product Sun Microsystems has provided Driver as an interface and Sun Microsystems lets the database vendors provide implementation classes to the driver interface as part of their database software. If we want to use Drivers in JDBC applications then we have to get Driver implementation from the respective database software.

Type 1 − JDBC-ODBC Bridge Driver
- In a Type 1 driver, a JDBC bridge is used to access ODBC drivers installed on each client machine. Using ODBC, requires configuring on your system a Data Source Name (DSN) that represents the target database. When Java first came out, this was a useful driver because most databases only supported ODBC access but now this type of driver is recommended only for experimental use o…
