What is JDBC ?

JDBC is Java Database Connectivity, a collection of APIs for connecting a Java application to a database. It is an abstraction over ODBC so as to provide Java clients an interface to connect to the database end.The latest update of the JDBC API is JDBC3.0. It contains many features, including scrollable result sets and the SQL:1999 data types.
The first version of JDBC(JDBC1.22 with JDK1.1.x release) had only one pacakge named java.sql.* but in JDBC2.0(released with Java2) there had been introduced several new features in two pacakges namely,java.sql.* and javax.sql.*
