JDBC type 3 driver

''Schematic of the Network Protocol driver''

The JDBC type 3 driver, also known as the network-protocol driver is a database driver implementation which makes use of a middle-tier between the calling program and the database. The middle-tier (application server) converts JDBC calls directly or indirectly into the vendor-specific database protocol. This differs from the type 4 driver in that the protocol conversion logic resides not at the client but in the middle-tier. However, like type 4 drivers, the type 3 driver is written entirely in Java. The same driver can be used for multiple databases. It depends on the number of databases the middleware has been configured to support. The type 3 driver is platform-independent as the platform-related differences are taken care by the middleware. Also, making use of the middleware provides additional advantages of security and firewall access. ==Also see== * JDBC type 1 driver * JDBC type 2 driver * JDBC type 4 driver Java platform
