UML use-cases and iterations

Question

How can I represent in a UML use case's diagram the fact that an action is iterative? For example: actor Admin can add new categories and new subcategories. A subcategory can have other subcategories, so admin can add a new subcategory in a subcategory. Thanks.

Answer 1

In an UML use case, you do not model the process, but the features ...

So you can't ...

Next time, at least provide your own schema to show that you worked at least a little ...

And if you provide some works, you could get a more helpful answer ...

Answer 2

Usually a use-case diagram is accompanied by a document describing its basic and alternate flows. Iterative behavior may described in the those flows (steps).
