Domain Selection Matrix

It is useful to view the characteristics of the domain models side by side, to match the characteristics and benefits of each implementation model to the needs of your organization. If the needs of your organization change, you can review this matrix to determine the optimal implementation model.

If you have already established an implementation model, it is a good idea to review the following chart to see the benefits or trade-offs of other domain models.
