<Li> Type 4, the pure - java driver that uses database native protocol . </Li> <P> Note also a type called an internal JDBC driver - a driver embedded with JRE in Java - enabled SQL databases . It is used for Java stored procedures . This does not fit into the classification scheme above, although it would likely resemble either a type 2 or type 4 driver (depending on whether the database itself is implemented in Java or not). An example of this is the KPRB (Kernel Program Bundled) driver supplied with Oracle RDBMS . "jdbc: default: connection" offers a relatively standard way of making such a connection (at least the Oracle database and Apache Derby support it). However, in the case of an internal JDBC driver, the JDBC client actually runs as part of the database being accessed, and so can access data directly rather than through network protocols . </P> <Ul> <Li> Oracle provides a list of some JDBC drivers and vendors </Li> <Li> Simba Technologies ships an SDK for building custom JDBC Drivers for any custom / proprietary relational data source </Li> <Li> CData Software ships type 4 JDBC Drivers for various applications, databases, and Web APIs . </Li> <Li> RSSBus Type 4 JDBC Drivers for applications, databases, and web services </Li> <Li> DataDirect Technologies provides a comprehensive suite of fast Type 4 JDBC drivers for all major database they advertise as Type 5 </Li> <Li> IDS Software provides a Type 3 JDBC driver for concurrent access to all major databases .
