title: Table has one to one relationship with many tables
body: <p>1) Can a table have a one-to-one relationship with a number of tables !?</p>
  
  <p>To clarify more, if I want to do an insert the first table will be affected and
  only one of the other tables will be affected .</p>
  
  <p>2) and if so, how the primary key will be ?</p>
  
  <p>3) also, what will the query look like if I want to retrieve a number of records
  from these tables ?</p>
