The JDBCTM API provides universal data
access from the JavaTM programming language.
Using the JDBC 2.0 API, you can access virtually any data source, from
relational databases to spreadsheets and flat files.
JDBC technology also provides a common base on which tools and alternate
interfaces can be built.
The JDBC 2.0 API includes two packages: the java.sql package,
known as the JDBC 2.0 core API,
and the javax.sql package, known as the JDBC
Standard Extension.
The JavaTM 2 SDK, Standard Edition,
includes the JDBC 2.0 core API and the JDBC-ODBC Bridge.
The JavaTM 2 SDK, Enterprise Edition,
includes the JDBC 2.0 core API and also the
JDBC 2.0 Standard Extension.
If you do not need everything that is included in the Enterprise Edition,
you can download the JDBC
Standard Extension separately.
Note that if the javax.sql package is
bundled with your JDBC 2.0 technology driver,
you will not need to download it.
JDBC Technology Drivers
To use the JDBC API with a particular database management system,
you need a JDBC technology-based driver to mediate between JDBC
technology and the database.
Depending on various factors, a driver might be written purely
in the Java programming language or
in a mixture of the Java programming language and
JavaTM Native Interface (JNI)
native methods.
The JDBC web site maintains a list of
vendors
with drivers currently available or under
development.
The latest SDK includes the JDBC-ODBC Bridge.
This JDBC technology-based driver makes most Open Database Connectivity
(ODBC) drivers available to programmers using the JDBC API.
The JDBC-ODBC Bridge Guide
describes the current status of this software.
