If Oracle is your database management tool of choice, then an application such as KS DB Merge Tools for Oracle is surely of great help. This software utility is designed for database comparison and synchronization, allowing you to compare data and schemas inside two Oracle databases and merge any changes that might occur.

To make it easier for you to spot differences, KS DB Merge Tools for Oracle displays data on two panels, each allowing a direct connection to an Oracle database. A few details are required to help you get started: the server's name and the port number, as well as the connection credentials. The connection can be tested to see if everything works as it should.

There are other connection options besides entering the credentials manually: KS DB Merge Tools for Oracle can use connection strings for each database.
