Hi saurabh,
There are two types of database links.
Explict database link the syntax is :-
CREATE DATABASE LINK <db link name>
CONNECT USING user_name identified by passwd USING connect_string;

Default database link the syntax is :-
CREATE DATABASE LINK <db link name>
CONNECT USING current_user
USING connect_string;
In this case, it will try to connect to the remote database with the user_name / passwd of the local database currently logged in.

to access table /view/synonym from a remote db use
select * from <table_name/view_name>@<dblink_name>;

But to make this db link and then to access first make the connect string of the remote database in the local machine in the tnsnames.ora using net 8 easy configuration tool.
