ODBC is the industry-standard interface by which database
clients connect to database servers. 

JDBC is a pure Java solution that does not follow the ODBC
standard. 

However, there is a bridge between JDBC and ODBC that allows
JDBC to access databases that support ODBC.

JDBC is the name of the protocol which is used to connect 
to the database whereas ODBC is the mechanism that is used 
to retrieve data from the database....JDBC is called the 
protocol and ODBC the subprotocol...

jdbc is used to connecting the database through the java 
language.but the odbc is common to all the database 
connection.

JDBC is platform independent whereas ODBC is platform 
dependent.

ODBC is used to connect any type of client with a server.
But JDBC is used to connect only java based clients to a 
server.  Anyway, JDBC requires ODBC for this.

JDBC technology is an api written in java,where as odbc is a
'c' interface written in c/c++ and cobol languages.
jdbc makes jdbcAPI calls
odbc tranforms jdbcAPI calls to odbc operations,these are 
sent to database server.

ODBC is a layer which is designed to communicate with 
different databases. when we give a command to odbc it 
talks with the specific database in its language we need 
not to worry about the database what we are communicating
Thats why it is called Opend Data Base Connectivity

JDBC is layer and it is having its own API which is having 
the commands to communicate with database. 

when we JDBCODBC Driver, this will take care of sending the 
java commands which can understand by ODBC.

Hi...
JDBC: It is developed in pure java language.But ODBC 
develop in C/C++ language using pointers,it is a microsoft 
product.
