Java Database Connectivity
JDBC is the part of the Java library which allows interaction with relational databases using SQL.
Developers can either code directly to the JDBCAPI or use SQLJ which allows SQL statements to be embedded directly into Java source.
Given the wide use of relational databases, JDBC is used in a large number of Java applications.

associated with Java Database Connectivity."
