The JDBC type 4 driver, also known as the native-protocol driver is a database driver implementation that converts JDBC calls directly into the vendor-specific database protocol. Java Database Connectivity, or JDBC, is an API for the Java programming language that defines how a client may access a database. ... A database is a collection of data. ...


The type 4 driver is written completely in Java and is hence platform independent. It provides better performance over the type 1 and 2 drivers as it does not have the overhead of conversion of calls into ODBC or database API calls. Unlike the type 1 and 2 drivers, it does not need associated software to work. Java is a reflective, object-oriented programming language developed initially by James Gosling and colleagues at Sun Microsystems. ... A cross-platform (or platform independent) programming language, software application or hardware device works on more than one system platform (e. ...


As the database protocol is vendor-specific, separate drivers, usually vendor-supplied, need to be used to connect to the database.

Types of JDBC technology drivers (354 words)
Note that some ODBC native code and in many cases native database client code must be loaded on each client machine that uses this type of driver.
Hence, this kind of driver is generally most appropriate when automatic installation and downloading of a Java technology application is not important.
Note that, like the bridge driver, this style of driver requires that some binary code be loaded on each client machine.

JDBC is a core API of Java 1.1 and later.
Type 4 indicates that the driver is written in Pure Java, and communicates in the database system's own network protocol.
