The Sun website at http: Some distinctive characteristic of type 2 jdbc drivers are shown below. The type 3 driver is platform-independent as the platform-related differences are taken care of by the middleware. Advantages for using this type of driver include the following: Also, use of this driver leads to other installation dependencies; for example, ODBC must be installed on the computer having the driver and the database must support an ODBC driver.

Not for large-scale applications. Best use is for controlled environments, such as an intranet. User needs to make sure the JDBC driver of the database vendor is loaded onto each client machine.

Oracle OCI driver is a type 2 driver.

A performance issue is seen as a JDBC call goes through the bridge to the ODBC driver, then to the database, and idbc applies even in the reverse process. Some ODBC native code and in many cases native database client code must be loaded on each client machine that uses this type of driver. Thus the performance is considerably improved.

This driver is server-based, so there is no need for any vendor database library to be present on client machines. It provides better performance over the type 1 and 2 drivers as it does not have the overhead of conversion of calls into ODBC or database API calls. It requires another server application to install and maintain. For performance reasons, the back-end server component is optimized for the operating system on which the database is running.

It tests the drivers by calling the method Driver. December Learn how and when to remove this template message.

It is installed inside the Java Virtual Machine of the client. There are 4 types of JDBC drivers available.

This driver is fully written in Java and hence Portable. This page was last edited on 25 Septemberat The middleware provides connectivity to many different databases. About Sun Adapter for Informix Next: To connect with individual databases, JDBC requires drivers for each database. The type 4 driver is written completely in Java and is hence platform independent. Written completely in Javatype 4 drivers are thus platform independent.

In order to develop and test for JDBC 2 functionality you need to:. Also, use of this driver advantagees to other installation dependencies; for example, ODBC must be installed on the computer having the driver and the database must support an ODBC driver.

Types of JDBC Drivers

Direct-to-database pure Java driver This style of driver converts JDBC calls into a network protocol that sends the converted packets–in a proprietary format–to be used directly by DBMSs, thus allowing a direct call from the client machine to the DBMS server and providing a practical solution for intranet access.

Please help improve it or discuss these issues on the talk page. However the type 2 driver provides more functionality and performance than the type 1 driver as it does not have the overhead of the additional ODBC function calls. Although it is possible to use ODBC without a driver manager by linking directly with the ODBC driver at build time, this option needlessly removes some beneficial functionality and the method of linking programs with the driver manager shared object Unix or DLL Windows provides three key results:.

The drivers listed in jdbc. This provides better performance than the type 1 and type 2 drivers as it does not have the overhead of conversion of calls into ODBC or database API calls. If we change the Database we have to change the native api as it is specific to a database 4.
