title: E-commerce Domain Model Feedback
body: <p>I've been working on putting together a rough conceptual model of an E-commerce website that basically allows users to resell concert tickets. It's purely conceptual and not something i'm actually making!</p>
  
  <p>Anyway I've put together a domain model and I was hoping for some feedback. I've made class model before and modelled databases but found it quite difficult differentiating between them.</p>
  
  <p>I've seen the words rich and anaemic thrown around a lot and I believe my model is anaemic. Would simply notating more behaviour make it rich?</p>
  
  <p>Are my relationships correct? Have I correctly used my aggregations and compositions?</p>
  
  <p>I would love any suggestions on improvements.</p>
  
  <p>Thanks in advance.</p>
