Oracle application software is one of SAP's biggest competitors, so I can
see why they are anxious to not depend on Oracle DBMS. Things would have
gotten really touchy had the Oracle-PeopleSoft merger gone through.
Since IBM is also a huge SAP customer for IBM internal systems, that doesn't
hurt either.
