title: Restaurant System database/text files
body: <p>I have a yearly project due for next week that iv been working on,  it's a restaurant /cafe point of sale system as an assignment to integrate everything we have learnt in c# so far. </p>
  
  <p>I'm stuck on a small problem I have a database of ingredients (like cheese tomatoes....)  and waiters I'd with username and what not. My problem comes in that I want to make a new order so an order is created and the customers items they ordered are added I just don't know how do I go about the following: </p>
  
  <ol>
  <li>Continuing a order?  The waiter places an initial order for the customers but how do I get the waiter who logs back in a later stage to see her active orders and then edit/add to those orders?  I had the idea of creating a text file then at the end of the whole text file and once the order is closed to then edit all the items sold and the materials used to sell them from the database?  But then there is no way to check if for example cheese is in Stock before they order a burger?  </li>
  </ol>
  
  <p>I basically want to be able to continue a order of the active waiter who is logged in and still be able to void any faults / check stock at the same time too.  </p>
  
  <p>It's a project for myself so no homework related or such I'm just stuck on how to overcome this. </p>
