Explain database link?

Answer Posted / Ajay Kumar Choudhary

A database link in Oracle provides a means to establish connectivity between two or more databases. It allows users to query data residing in remote databases as if it were local. Database links are created using the CREATE DATABASE LINK statement and can be used in SQL statements to access remote data using the @ symbol followed by the database link name.
