Oracle 8i and 9i are different versions of the database.
Oracle9i is a newer release to Oracle8i, it will have more
enhancements, fixes etc. New features are available to both
developers and administrators.
With Oracle each new version contains the same
functionality as the previous version. So Oracle 9i is
backwards compatible with 8i. Oracle 9i does many things
differently internally so they are not exactly the same
database engine. And Oracle 9i has a host of new features
designed to make the database more stable, easier to manage
and increase functionality. There are so many new features
that Oracle Corp. provides a complete manual listing these
new feature. The Oracle 9i New Features manual can be found
on Oracle's Technet site at if you are interested. You will
need to register for a free account if you want to view
documentation on that site.
