Type-1
JDBC-to-ODBC Bridge Driver
– connects Java to a Microsoft ODBC
(Open Database Connectivity)
data source. This driver requires the ODBC
driver to be installed on the
client computer and configuration of the ODBC
data source.
Type-2
Native-API, Part Java
Drivers – enable JDBC programs to use
databasespecific
APIs (normally written in C
or C++) that allow client programs to
access databases via the Java
Native Interface. This driver translates
JDBC into database-specific
code.
Type-3
JDBC-Net Pure Java Drivers
– take JDBC requests and translate them
into a network protocol that
is not database specific. These requests are
sent to a server, which
translates the database requests into a databasespecific
protocol.
Type-4
Native-protocol Pure Java
Drivers – convert JDBC requests to
database-specific network
protocols, so that Java programs can connect
directly to a database.
