title: Mappling Multiple Tables To Entity In EF5
body: <p>Edited For Clarity:</p>
  
  <p>Im working on a webapp build ontop of an existing DB in which i may not change the schema. Much of the data i need is pulled across multiple tables, linked by FKs</p>
  
  <p>How can i create entities in EF that pull from multiple tables (most have a 1 to 0/1 constraint) to more easily work with the data I need.</p>
  
  <p>For example I have 2 employees table, one with account info, and one that if populated is demographic information. If none was input then a record for that employee will not exist in that DB.</p>
  
  <p>What i tried (with no success so far) was create my own "Employee" entity, imported user table, and user_demographic table. Then cut \ paste the properties i wanted into my Employee Entity, and mapped the tables, when i added the demographic table I set the PK of the demo table to the FK of the user table, however when i try to validate this EF complains about fragment mappings?</p>
