SOLUTION

• Sun has defined four categories of JDBC drivers.
• In order to connect a Java application to a database using JDBC, you need to use a JDBC driver.
• This driver acts as an intermediary between your application and the database.
• Sun has defined four categories of JDBC drivers. The categories delineate the differences in architecture for the drivers.
• One difference between architectures lies in whether a given driver is implemented in native code or in Java code.

There are 4 types of JDBC drivers:

1. Type-1 driver or JDBC-ODBC bridge driver.
2. Type-2 driver or Native-API driver.
3. Type-3 driver or Network Protocol driver.
4. Type-4 driver or Thin driver
