You are discussing three very different things here, an ENC is, at it's most basic form, just a classifier that says node X should apply class Y - though there are much more sophisticated things that one can do with an ENC, in the scope of this example lets leave it at that. What class Y actually is, is where roles and profiles come in. Roles and profiles are merely a design pattern for laying out your classes to add some layers of abstraction between component modules (the actual cogs) and roles (business logic) - when people adopt roles and profiles they tend to classify just the nodes role in the ENC. Hiera is a different concept entirely and is used to provide hierarchical data lookups which determine what data values are applied based on a pre-determined series of overrides that are customized to your particular environment. https://www.youtube.com/watch?v=ZpHtOnlSGNY is a talk I did on this some time ago, and towards the end Hiera and ENCs are touched on Some of the relevant parts are; http://www.slideshare.net/PuppetLabs/roles-talk - #71 Hiera - #88 ENC - #92 Stack diagram Hope this helps.
