Here's a typical (OFA) structure of an ORACLE 10g install:

   ORACLE_BASE = /u01/app/oracle/
   ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1

Consider ORACLE_BASE as a baseline directory off of which we fan out while
ORACLE_HOME is the final destination for a particular ORACLE release version.

As your server lives and goes through multiple upgrades you'll have the same 
ORACLE_BASE but multiple ORACLE_HOME's underneath it.
