DBDiff for Oracle Upgrade for Windows

The description of DBDiff for Oracle Upgrade - Play With New Friends

DBDiff for Oracle is a database utility that performs a comparison between two Oracle databases. It can also create an upgrade script.Any Oracle database can be compared, the databases do not need to be on the same version of Oracle (7.3.3, 7.3.4, 8, 9, etc), they don¿t even need to be on the same machine, as long as they are both accessible from the machine running DBDiff. DBDiff uses a carefully planned and designed algorithm for performing the quickest, most accurate comparison between the databases; this algorithm allows for multiple levels of comparison to be performed on the databases.
