    Interpretation and understanding of Oracle version numbering:

    First digit is Major database release number
    Second digit is Database maintenance release number
    Third digit is Application server release number
    Fourth digit is Component specific release number
    Fifth digit is Platform specific release number

    For Example take output of above sample:
    Oracle 10.2.0.1.0

    Explained:

    Oracle 10 <=Major database release number
    .2 <=Database maintenance release number
    .0 <=Application server release number
    .1 <=Component specific release number
    .0 <=Platform specific release number
