mysq-connector.jar, ojdbc_6.jar or sqjdbc4.jar because they are easy to use, just drop their JAR in classpath and you are done, but knowing bit of history behind it not bad at all. The client application connects directly to the database server. It is not written entirely in java. Your application server might use a Type 1, 2, or 4 driver to communicate with the database, understanding the nuances will prove helpful. http://depthvision.net/jdbc-driver/different-types-of-database-drivers-in-java.html
Follows a three-tier communication approach. By the way here are there full names : Type 1 JDBC Driver is called JDBC-ODBC Bridge driver (bridge driver) Type 2 JDBC Driver is referred as Native-API/partly Java driver (native If the Empire had over 25,000 Star Destroyers, why were only 27 at the Battle of Endor? I hope this help you to reason why JDBC has so many types of driver. https://www.progress.com/faqs/datadirect-jdbc-faqs/what-are-the-types-of-jdbc-drivers
This kind of driver is extremely flexible, since it requires no code installed on the client and a single driver can actually provide access to multiple databases. Disadvantages: Network support is required on client machine. The following figure shows a side-by-side comparison of the implementation of each JDBC driver type.
No support from JDK 1.8 (Java 8) onwards. The type 1 driver is not considered a deployment-level driver, and is typically used for development and testing purposes only. Like type 4 drivers, the type 3 driver is written entirely in Java. Jdbc Driver Oracle December 14, 2013 at 4:02 PM Anonymous said...

Type 5 drivers (such as DataDirect Connect for JDBC drivers) offer advanced functionality and superior performance over other driver types. Which Of The Following Is Not A Jdbc Driver What's a good strategy? There are mainly 4 types of JDBC drivers in Java, those are referred as type 1 to type 4 jdbc drivers. The driver converts JDBC method calls into native calls of the database API.
Type 5 drivers (such as DataDirect Connect for JDBC drivers) offer advanced functionality and superior performance over other driver types. Not all databases have a client-side library. Jdbc Driver Download When he says performance and portability, interviewer was quite impressed. Class Connection Type 4 Driver Is my OS 32-bit or 64-bit?
The vendors supplies the specific driver classes. have a peek at these guys Advantage: No client side library is required because of application server that can perform many tasks like auditing, load balancing, logging etc. Disadvantage: The Native driver needs to be installed on the each client machine. It depends on the number of databases the middleware has been configured to support. Jdbc-odbc Bridge 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. The middle-tier (application server) converts JDBC calls directly or indirectly into a vendor-specific database protocol. Type 1 drivers also don't support the complete Java command set and are limited by the functionality of the ODBC driver. check over here This driver is native code and not Java, and is closed source.
It is suitable for the web.3. Thin Driver In Jdbc The net protocol can be designed to make the client JDBC driver very small and fast to load.5. The vendor-specific driver must be installed on each client machine.
These drivers are not portable. If we change the Database we have to change the native api as it is specific to a database4. Unsourced material may be challenged and removed.
