Here “System” is the top-level component and it has one sub-component - “Memory”. This has two parts, a class, and a flag. The class has two source elements – files in this case.

Parts could be elements of a programming language, such as a class or an object, but they can also be any other element of the internal or external structure of a component.

Different types of source elements are supported, such as ps:file, that simply copies a file from one place to a specified destination.
