A module provides structure (with hierarchy and heading auto-numbering) while a collection is a simple grouping of artifacts. A collection can contain almost any kind of artifacts, including modules. There is one exception: a collection does not include other collections. A module does not include other modules (or collections).
You use modules to create specifications or other sets of information with parent-child relationships among the data.
You use collections to group things that are related, for example, for a particular milestone/iteration of a project, artifacts on the same topic, etc.
Collections and modules are both ways of grouping other artifacts. They are artifacts themselves (with a URL, name, etc.). Folders and filters are other less formal ways of grouping artifacts.
DOOR 9.x uses modules as the fundamental organizing concept. Likewise we expect users of DOORS Next Generation will most often use modules.
