MySQL's Connector/J driver is a Type 4 driver. Your application server might use a Type 1, 2, or 4 driver to communicate with the database, understanding the nuances will prove helpful. JDBC-ODBC driver translates JDBC calls into ODBC callas and send them to ODBC driver for passing to database. As the database protocol is vendor specific, the JDBC client requires separate drivers, usually vendor supplied, to connect to different types of databases. http://prettyfile.com/jdbc-driver/how-many-types-of-jdbc-drivers-are-available.php
Again none of this has to do with functionality; however, they all impact how to deploy, how to debug, and how to configure the database connection. You can think of the application server as a JDBC "proxy," meaning that it makes calls for the client application. share|improve this answer answered Jul 15 '13 at 16:33 Edwin Buck 49.4k35998 add a comment| up vote 10 down vote The "type" refers to how the driver implements the API.

Written completely in Java, type 4 drivers are thus platform independent. 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. Jdbc Driver Oracle The ODBC driver needs to be installed on the client machine. 2) Native-API driver The Native API driver uses the client-side libraries of the database.

Three main reason I recommend type 4 driver :1) They are fastest2) They are portable because implemented in pure 100% Java.3) They don't require any setup, just include respective JAR in Thin Driver In Jdbc First the DriverManager tries to use each driver in the order it was registered. (The drivers listed in jdbc.drivers are always registered first.) It will skip any drivers that are untrusted Maintenance of Network Protocol driver becomes costly because it requires database-specific coding to be done in the middle tier. 4) Thin driver The thin driver converts JDBC calls directly into the Yesterday, one of my friend ask about difference between JDBC Type 3 and Type 4 driver?

Unlike in most other jars the imports are not from ojdbc14, they are from java.sql which is in rt.jar itself. 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. Disadvantages The vendor client library needs to be installed on the client machine. Class file in Java - things to know for programmer...
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. Since type 1 driver act as bridge between JDBC and ODBC and that's why its called JDBC-ODBC bridge driver. What Are DataDirect's JDBC Diagnostic Capabilities? These drivers are typically provided by the database vendors and used in the same manner as the JDBC-ODBC Bridge.
