This section provides guidance on how to effectively partition
models in a team development environment.
Partitioning UML models
You can partition a UML model to help organize work in
a team development environment. For example, you can divide a model
so that different people can work on separate parts of the model at
the same time. You can either create a separate physical model from
a package that becomes a new top-level logical model or you can create
a fragment to logically divide a model into multiple levels and sections.
