In Oracle, you can utilize a Database Link to access another database. Here are the steps to access another database using a Database Link.

  1. Create a database connection in the target database.
CREATE DATABASE LINK link_name
  CONNECT TO username IDENTIFIED BY password
  USING 'tns_service_name';

The link_name represents the name of the link, username and password refer to the username and password for the target database, and tns_service_name is the TNS service name for the target database.

  1. Execute SQL statements using database connections.
SELECT * FROM table_name@link_name;

table_name is the name of the table in the target database, while link_name is the database link name created in step 1.

By following the above steps, you can use a database link to access another database in Oracle.
