Comparing and merging data objects

When a comparison of data objects is performed, a comparison editor opens in the editor area. The differences between data objects are highlighted in the comparison editor, so that you can browse and copy changes between the compared resources. After you copy the changes, you can generate, save, and run delta DDL scripts to merge the changes.
When you compare data objects, the standard compare editor is customized. For data objects, you can perform basic compare tasks, plus the following additional tasks:
Compare With > Another Data Object
Compares a data object with another data object. If you select this option, a window opens so that you can select another data object for the comparison.
Compare With > Original Source
Compares a data object with the original version of the object. This option is available only if you select an object that was reverse engineered from another data source.
