title: EMF Modeling question: container and containment
body: <p>I'm familiar with Entity Framework and code-first design in Visual Studio, but I'm getting my feet wet with Eclipse.  That said, I'm trying to understand how some of the properties for eReference attributes translate in ecore models.  Specifically, when I read about container and containment, I'm finding myself lost.  Are these fields somehow translatable into either SQL Foreign Key relationships or entity model object relationships?  I can understand both of those pretty well.  Specifically, in either SQL or EF terms, what does it mean when container=true, what does it mean when containment=true.</p>
