title: How to draw a login procedure in BPMN
body: <p>For a school project we are investigating the way to complex login procedure of our local library. We are currently making a AS-IS model in BPMN but because we don't know the language very well we are a little bit confused:</p>
  
  <p>Should every "Login" process have an incoming flow from a datastore? Same for "checking" if accounts are linked to each other? </p>
  
  <p>What is the correct way to handle with this? Because it is a model for an application a lot connections with datastores are being made and would make the model messy if I used them everywhere.</p>
  
  <p>Take a look to our draft model down here.</p>
