The JVM can manage all aspects of the application-to-database connection; this can facilitate debugging.

It is fully written in Java language. It depends on the number of databases the middleware has been configured to support. The type 1 driver is not considered a deployment-level driver, and is typically used for development and testing purposes only. Jdbc Driver Oracle Type 3 JDBC Driver All Java/Net-protocol driver Type 3 database requests are passed through the network to the middle-tier server.
Please help improve this article by adding citations to reliable sources. Jdbc Driver Download May 25, 2012 at 5:42 AM Anonymous said... 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. https://www.progress.com/faqs/datadirect-jdbc-faqs/what-are-the-types-of-jdbc-drivers The type 3 driver typically provides support for features such as caching (connections, query results, and so on), load balancing, and advanced system administration such as logging and auditing. 6.

This was liked by Database vendors though because they can reuse there existing native libraries. http://tutorials.jenkov.com/jdbc/driver-types.html This driver has no additional translation or middleware layer, which improves performance tremendously. Types Of Jdbc Drivers In Java With Examples 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. Jdbc Driver Mysql To connect with individual databases, JDBC (the Java Database Connectivity API) requires drivers for each database.
Type 4 driver – Database-Protocol driver (Pure Java driver) Schematic of the Native-Protocol driver The JDBC type 4 driver, also known as the Direct to Database Pure Java Driver, is a check over here Retrieved 2016-11-18. I use JDBC 4 drivers for quite a while (several years) and I have never met the older version. This driver is native code and not Java, and is closed source. Jdbc-odbc Bridge Driver
This driver is platform dependent. This differs from the type 4 driver in that the protocol conversion logic resides not at the client, but in the middle-tier. Sun's/Oracle's JDBC-ODBC Bridge was removed in Java 8 (other vendors' are available). If a driver has been written so that loading it causes an instance to be created and also calls http://prettyfile.com/jdbc-driver/how-many-types-of-jdbc-drivers-are-available.php Multi thread model.

Interview Candidate Aug 27th, 2004 0 1150 Java Answer First Prev Next Last This Question is not yet answered! The JDBC Client driver written in java, communicates with a middleware-net-server using a database independent protocol, and then this net server translates this request into database commands for that database. A single driver can handle any database, provided the middleware supports it. weblink The other implication is that any application using a type 1 driver is non-portable given the binding between the driver and platform.

Have you recently used older version? The use of this driver is discouraged if the alternative of a pure-Java driver is available. May 24, 2012 at 10:42 AM Javin Paul said... 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.
These drivers don't translate the requests into an intermediary format (such as ODBC). 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. The middle-tier (application server) converts JDBC calls directly or indirectly into a vendor-specific database protocol. JDBC-ODBC driver translates JDBC calls into ODBC callas and send them to ODBC driver for passing to database.
If the middle-tier server can in turn use Type1, Type 2 or Type 4 drivers.Type 3: All Java/ Net-Protocol Driver Advantage 1. let us know if you come across some news on JDBC 5 driver. Not good for the Web. Yes, you would hardly use anything but other than type 4 JDBC driver e.g.
Type 4: 100% Pure Java In a Type 4 driver, a pure Java-based driver communicates directly with the vendor's database through socket connection. The different types of jdbc drivers are: Type 1: JDBC-ODBC Bridge driver (Bridge) Type 2: Native-API/partly Java driver (Native) Type 3: AllJava/Net-protocol driver (Middleware) Type 4: All Java/Native-protocol driver (Pure) 4 The JDBC-ODBC Bridge that comes with JDK 1.2 is a good example of this kind of driver. I couldn't answer because I wasn't aware of motivation.
The middle-tier then translates the request to the database.
