You can compare two or three models to find the differences between
them. When you compare models in a parallel development environment, 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.
