The JDBC driver gives out the connection to the database and implements the protocol for transferring the query and result between client and database. This technology isn't suitable for a high-transaction environment. Advantages Since the communication between client and the middleware server is database independent, there is no need for the database vendor library on the client. E.g.: IDA Server Disadvantages Requires database-specific coding to be done in the middle tier. weblink
Difference between type 2 and type 3 JDBC driver? It depends on the number of databases the middleware has been configured to support. What is type 3 driver in JDBC? Not good for the Web.Type 2 JDBC DriverNative-API/partly Java driverThe distinctive characteristic of type 2 jdbc drivers are that Type 2 drivers convert JDBC calls into database-specific calls i.e. https://en.wikipedia.org/wiki/JDBC_driver
Repeat last command N times "A patients guide" or "A patient's guide"?

The driver is platform-dependent as it makes use of ODBC which in turn depends on native libraries of the underlying operating system the JVM is running upon. Just make sure to put them into your Java application's classpath when you connect to database from Java program. The type-2 drivers again use a Java (JDBC) API; however, they bridge the calls into a C or C++ style shared library, which then handles the real connection. https://en.wikipedia.org/wiki/JDBC_driver Advantage: No client side library is required because of application server that can perform many tasks like auditing, load balancing, logging etc.
This is mostly theoretical question which some guys prefer to ask(I am not from them) and one of my reader asked this question so I thought to just summarize it. Which Of The Following Is Not A Jdbc Driver Requires database-specific coding to be done in the middle tier. External link in |website= (help) ^ "Life after sun.jdbc.odbc.JdbcOdbcDriver". This driver is fully written in Java and hence Portable.
As a result, you need some knowledge of the application server's configuration in order to effectively use this driver type. http://www.javatpoint.com/jdbc-driver java sql jdbc share|improve this question edited Aug 11 '13 at 19:09 Eric Leschinski 59k28252216 asked Jul 15 '13 at 16:06 Ishan Bhatt 3391217 Here is the link to Jdbc Driver Download It was pretty easy to use and deploy as well just include driver's jar in classpath and you are ready. Class Connection Type 4 Driver Native-API/partly Java driver or Type 2 JDBC driver This is also called type 2 driver and its slightly better than type 1 JDBC driver.
Follows a three-tier communication approach. http://depthvision.net/jdbc-driver/different-drivers-in-java.html It was inteded for Java 1.4 and should not be used any more. May 24, 2012 at 10:42 AM Javin Paul said... Type 1 JDBC driver is the poorest in terms of portability and performance while type 4 JDBC driver is highly portable and gives the best performance. Jdbc-odbc Bridge Driver
Contents 1 Type 1 driver – JDBC-ODBC bridge 1.1 Advantages 1.2 Disadvantages 2 Type 2 driver – Native-API driver 2.1 Advantages 2.2 Disadvantages 3 Type 3 driver – Network-Protocol driver (middleware Native API must be installed in the Client System and hence type 2 drivers cannot be used for the Internet.2. This is the oldest JDBC driver, mostly used to connect database like MS Access from Microsoft Windows operating system. http://depthvision.net/jdbc-driver/different-jdbc-drivers-java.html The type 1 driver is not considered a deployment-level driver, and is typically used for development and testing purposes only.
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 Jdbc Odbc Full Form This differs from the type 4 driver in that the protocol conversion logic resides not at the client, but in the middle-tier. Functions Sends JDBC API calls to a middle-tier net server that translates the calls into the DBMS-specific network protocol.The translated calls are then sent to a particular DBMS.
The following figure shows a side-by-side comparison of the implementation of each JDBC driver type. Type 1 drivers also don't support the complete Java command set and are limited by the functionality of the ODBC driver. https://docs.oracle.com/. Thin Driver In Jdbc This type includes, for example, the widely used Oracle thin driver.
Though both type 1 and type 2 drivers are not written in Java, there was some significant difference between them. The middle-tier (application server) converts JDBC calls directly or indirectly into a vendor-specific database protocol. This driver supports all Java applications except applets. That requires database native client library e.g.ocijdbc11.dlland if that's not present in the machine then your Java program will throwjava.lang.unsatisfiedlinkerror no ocijdbc11 in java.library.path error at run time.
Advantages As there is no implementation of JDBC-ODBC bridge, it may be considerably faster than a Type 1 driver. Next TopicSteps To Connect To The Database In Java <
This driver had very poor performance because of several layers of translation which took place before your program connects to database.

How to use Final keyword in Java?
Performance of type 4 JDBC driver is also better than type 3 driver because of direct connectivity to database as opposed to 3 tier architecture of type 3 driver. Hello,It is possible to have 2 releases of the same jdbc driver on the same machine ? If we change the Database we have to change the native api as it is specific to a database4. Yesterday, one of my friend ask about difference between JDBC Type 3 and Type 4 driver?
The middleware layer added may result in additional latency, but is typically overcome by using better middleware services. It may sometimes be the case that more than one JDBC driver is capable of connecting to a given URL. Since it required native API to connect to DB client it is also less portable and platform dependent. The same client-side JDBC driver may be used for multiple databases.
