What is Difference between Thin client driver and Thick Client driver?
Thick driver – type 1 and type 2 JDBC drivers are called thick drivers.It provides JDBC access via ODBC drivers. ODBC binary code, and in many cases, database client code, must be loaded on each client machine that uses such a driver. and as the program is connected to database by an extra layer, hence thick drivers.

Thin drivers: Drivers converts JDBC calls into the network protocol, used directly by DBMS, allowing a direct call from the client machine to the DBMS server and providing a practical solution for intranet access.
