I want to know the answer to the following question:
What's the name of the HP database that's similar to IANA but not compatible with it?
All the background I'm provided with is that "This database is used by many computer software systems, including most Unix-like operating systems, Java, and the Oracle RDBMS; HP's "tztab" database is similar but incompatible.". Is that enough to answer the question?
Answer: yes
