    there is no correct answer but one can clearly say that they are the different versions of oracle and 8i is 1st ,9i is 2nd and 10G is the latest......!

    Oracle 8i and 9i are different versions of the database. It's like asking what's the difference between Windows 95 and Windows 98!

    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.

    Oracle 9i has better features than Oracle 8i like better concurrency control,better internet security ,i stands for internet and Oracle 10g is based on Grid Computing and distributed system rather than on client/server technology.

    oracle 8i and 9i are the internet versions where as 10g and latest versions are the grid versions. huge amount of users can be connected in at a time in grid version rather than internet versions.

    oracle 8i & 9i- i stands for internet
    oracle 10g- g for grid control
    grid control :if there are n number of database and maintained with 1 grid(server)
    there should be many clients but only 1 server.
    if we install oracle 10g in desktop, then both severe and client are installing in same sys.
    we can install server at 1sys and client on other sys. and can be accessed through the use of grid computing...
