Java Database Connectivity
JDBC is a Java API for executing SQL statements. (As a point
of interest, JDBC is a trademarked name and is not an acronym; nevertheless,
JDBC is often thought of as standing for “Java Database Connectivity”.) It
consists of a set of classes and interfaces written in the Java programming
language. JDBC provides a standard API for tool/database developers and makes
it possible to write database applications using a pure Java API.
Using JDBC, it is easy to send SQL statements to virtually any
relational database. In other words, with the JDBC API, it isn't necessary to
write one program to access a Sybase database, another program to access an
Oracle database, another program to access an Informix database, and so on. One
can write a single program using the JDBC API, and the program will be able to
send SQL statements to the appropriate database. And, with an application
written in the Java programming language, one also doesn't have to worry about
writing different applications to run on different platforms. The combination
of Java and JDBC lets a programmer write it once and run it anywhere
Java, being robust, secure, easy to use, easy to understand,
and automatically Downloadable on a network, is an excellent language basis for
database applications. What is needed is a way for Java applications to talk to
a variety of different databases. JDBC is the mechanism for doing this. JDBC
extends what can be done in Java. For example, with Java and the JDBC API, it
is possible to publish a web page containing an applet that uses information
obtained from a remote database. Or an enterprise can use JDBC to connect all
its employees (even if they are using a conglomeration of Windows, Macintosh,
and UNIX machines) to one or more internal databases via an intranet.
