title: Confused about Bounded Contexts and SubDomains
body: <p>I've read Eric Evan's book and am reading Vaughn Vernon's book now. I'm in the second chapter where he talks about subdomains and bounded context and am thoroughly confused now.</p>
  
  <p>From what I was able to distill, there should be a 1:1 relationship between a BC and an SD. However, I read in other places that this isn't necessarily the case.</p>
  
  <p>Can someone explain to me the relationship between a BC and SD?</p>
