Well, it's a bit more complicated than that..

OFA guidelines say that $ORACLE_HOME shoud be in the form of e.g. 

And application (DB) is installed into its $ORACLE_HOME and thus one can 
have many different installations of many different versions.

Then there are other directories under $ORACLE_BASE that usually contain 
Oracle Inventory (of installed software) and DB data files etc.

Usually everything under $ORACLE_BASE is created and taken care by 
Oracle Universal Installer (which is Java application).

Another issue may be where to place oratab file.  It is located in 
/var/opt/oracle/oratab on SunOS and in /etc/oratab on other Unixes.
