There are different categories of database link:
1) private link
2) public link

Other category based on access is:
1) connected user
2) fixed user
3) current user

With the combination of all the above 5 points we can create database link with
different characteristics.

Cluster key is a related column of tables in the cluster. For example, in Table EMP which has (EMP NO, EMP NAME, DEP NO, etc ) and DEPT which has (DEPT NAME, DEPT NO etc), DEPT NO is the cluster key in this cluster.

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.
