What is JDBC Thin driver?

The JDBC Thin driver is a pure Java, Type IV driver that can be used in applications and applets. It is platform-independent and does not require any additional Oracle software on the client side. The JDBC Thin driver communicates with the server using SQL*Net to access the Oracle Database.

What is a JDBC thin client?

The JDBC Thin client is a pure Java, Type IV driver. It is lightweight and easy to install. It provides high performance, comparable to the performance provided by the JDBC Oracle Call Interface (OCI) driver. The JDBC Thin driver is written entirely in Java, and therefore, it is platform-independent.

Why Thin driver is preferred for JDBC?

Thin driver directly converts the JDBC calls into vendor database specific protocols without any intermediate transformation. It is implemented using Java. Advantages: faster performance compared to the other drivers.

  • Type 1: JDBC-ODBC bridge.
  • Type 2: partial Java driver.

  1. Install or locate the database you want to access.
  2. Include the JDBC library.
  3. Ensure the JDBC driver you need is on your classpath.
  4. Use the JDBC library to obtain a connection to the database.
  5. Use the connection to issue SQL commands.
