You can compare two or three models to find the differences
between them. When you compare models, the models must have a common
ancestor.
You can compare models outside a source-controlled environment
or within a team environment using a configuration management system,
such as IBM
® Rational
® ClearCase
®.
When you compare two versions of a model, their differences are displayed.
When you compare three models, two sets of differences are displayed:
- Differences between one version (the left
contributor) and the common ancestor
- Differences between the other version (the right contributor)
and the common ancestor
The differences that conflict between the two sets are displayed
as conflicts.
