Tree
This section analyses the various options of setting up a DSfW tree and the associated limitations.

Using a Pyramid Design
With a forest designed in the form of a pyramid, managing and initiating changes to large groups,
and creating logical partitions are easier. This structure is best suited for large organizations with
operations spread out across the globe.
Using a Flat Design
The alternative to the pyramid design is a flat tree that places all objects at one level of the tree.
However, the flat tree design is not supported in DSfW.
DSfW can have only one top level domain and all the other domains need to be organized
underneath the top level domain.
If you have mapped an existing container to a domain, you cannot map the sibling containers to
create a domain. It is also not possible to partition the root container and map it to create a DSfW
forest.
