If you have used some architecture diagram Not good for the Web. 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 or when no other alternative is available. The other implication is that any application using a type 1 driver is non-portable given the binding between the driver and platform. Mostly obsolete now 5.

Further, these drivers can be downloaded dynamically. As the database protocol is vendor specific, the JDBC client requires separate drivers, usually vendor supplied, to connect to different types of databases.

JDBC – Driver Types

If you have used some architecture diagram Written completely in Javatype 4 drivers are thus platform independent. This article may be too technical for most readers to understand. Mostly obsolete now 5. So it cannot be used in internet due the client side software needed Type3 – Java to Network Protocol Driver Pure Java drivers that use a proprietary network protocol to communicate with JDBC middleware on the server The middleware then translates the network protocol to database-specific function calls Do not require native database libraries in the client side and can connect to many different databases in the backend Can be deployed over the Internet without client installation Requires database-specific coding to be done in the middle tier.


The drivers listed in jdbc.

This kind of driver is extremely flexible, you don’t need to install special software on the client or server. The socket information is then translated by the middleware application server into the call format required by the DBMS, and forwarded to the database server. This differs from the type 4 driver in that the protocol conversion logic resides not at the client, but in the middle-tier. Driver interface in their database driver. Please help improve it or discuss these issues on the talk page.

The JDBC type 3 driver, also known as the Pure Java driver for database middleware, [7] is a database driver implementation which makes use of a middle tier between the calling program and the database. Different way for DB Connection.

Disadvantage With type 4 drivers, the user needs a different driver for each database. Because of the proprietary nature of their network protocols, database vendors usually supply type 4 drivers. It requires another server application to install and maintain. JDBC technology drivers fit dagram one of four categories. A performance issue is seen as diqgram JDBC call goes through the bridge to the ODBC driver, then to the database, and this applies even in the reverse process.

What Are the Types of JDBC Drivers?

No cleanup reason has been specified. It will skip any drivers that are untrusted code unless they have been loaded from the same source as the code that is trying to open the connection.


Type 1 drivers also don’t support the complete Java command set and are limited by the functionality of the ODBC driver. From Wikipedia, the free encyclopedia. Please help improve this article if you can.

JDBC – Driver Types

This is the highest performance driver available for the database and is usually provided by dkagram vendor itself. March Learn how and when to remove this template message. The type 3 driver is platform-independent as the platform-related differences are taken care of by the middleware. The use of this driver is discouraged if the alternative of a pure-Java driver is available.

Further, these drivers can be downloaded dynamically.

They are the most efficient amongst all driver types. They are the slowest of all driver types. The distinctive characteristic of type 2 jdbc drivers are that Gype1 2 drivers convert JDBC calls into database-specific calls i.

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. This driver is server-based, so there is no need for any vendor database library to be present on client machines. The first driver that recognizes the URL makes the connection.
