Remote jdbc Driver Client-side Description
It consists of a driver which implements the JDBC driver API (all the interfaces from the java.sql package). Thus the application program can still adhere to the JDBC user API but register and load the remote jdbc driver in case of any database instead of having the specific jdbc driver classes for that database to be present at the client machine.
Communication is both from the client-side to server-side (to request connection, prepare and execute query statements) and from server-side to the client-side (for getting the result-set for any query execution).
