Yes you can do it in oracle too and it works in both directions. In fact
you can even do the link with non-oracle databases.

*********
Use the CREATE DATABASE LINK statement to create a database link. A
database link is a schema object in one database that enables you to
access objects on another database. The other database need not be an
Oracle Database system. However, to access non-Oracle systems you must
use Oracle Heterogeneous Services.

Once you have created a database link, you can use it to refer to tables
and views on the other database. In SQL statements, you can refer to a
table or view on the other database by appending @dblink to the table or
view name. You can query a table or view on the other database with the
SELECT statement. You can also access remote tables and views using any
INSERT, UPDATE, DELETE, or LOCK TABLE statement.
