This kind of driver is extremely flexible, you don't need to install special software on the client or server.

Disadvantages: Performance degraded because JDBC method call is converted into the ODBC function calls. All four implementations show a Java application or applet using the JDBC API to communicate through the JDBC Driver Manager with a specific JDBC driver. Anyway out of all those 4 types, JDBC-ODBC Bridge driver is most common for connecting SQL Server, MS Access and mostly on training and development. Jdbc Driver Oracle After some reasearch I found that main reason of so many differnet types of driver in Java is portability.

Coming to type of drivers, well its different ways in which they interact with DB which classifies them but ultimately aim is same i.e. Jdbc Driver Mysql to connect to DB.

For example, when connecting to a given remote database, it might be possible to use a JDBC-ODBC bridge driver, a JDBC-to-generic-network-protocol driver, or a driver supplied by the database vendor. Also, making use of the middleware provides additional advantages of security and firewall access. Jdbc-odbc Bridge Driver

Type 2 driver – Native-API driver[edit] Schematic of the Native API driver The JDBC type 2 driver, also known as the Native-API driver, is a database driver implementation that uses the What is Bean scope in Spring MVC framework with Ex... If the middle-tier server can in turn use Type1, Type 2 or Type 4 drivers.               Type 3: All Java/ Net-Protocol DriverAdvantage1. Type 1 drivers are used for testing JDBC applications against an ODBC data source.

The middleware server (which can be a full-fledged J2EE Application server) can provide typical middleware services like caching (of connections, query results, etc.), load balancing, logging, and auditing. Thin Driver In Jdbc Please help improve this article by adding citations to reliable sources. If the driver is optimized to be so fast that the JNI setup / tear down calls are negligible in cost, then perhaps it might outperform type-4 drivers.

It tests the drivers by calling the method Driver.connect on each one in turn, passing them the URL that the user originally passed to the method DriverManager.getConnection.

How Do I Improve JDBC Performance? See the JDBC Overview page on the Sun Microsystems web site for details about the four types of JDBC drivers. It was pretty easy to use and deploy as well just include driver's jar in classpath and you are ready. Type 2 drivers are useful in situations, where a type 3 or type 4 driver is not available yet for your database.

The JDBC driver gives out the connection to the database and implements the protocol for transferring the query and result between client and database. How Does JDBC Work? JDBC technology drivers fit into one of four categories.[2] JDBC-ODBC bridge Native-API driver Network-Protocol driver (Middleware driver) Database-Protocol driver (Pure Java driver) or thin driver. In contrast, a Type 3 driver is a single JDBC driver used to access a middleware server, which, in turn, makes the relevant calls to the database.
