while creating the table associations, don't you have to specify the key? Also, association and aggregation are different. Association is Person and his Address voohinchukondi, a person can have only one residential address, both Person and Address tables will have to use the same Person_Id. Aggregation lo Order and Parts, an Order can have multiple (sometimes repetitive Parts). Parts lo associated Order_Id vundaali general gaa.. named query sarigga gurthu ledu, but you'd have to specify what column goes into which property for every row correctly in the response-cursor.
