    Hi Furqnaz,
    What is the query that you have?
    Are you wishing me just to draw the ERD?
    Is there a logical issue with the structure?

    furqnaz question sounds like a typical problem given for homework in database class. i remember [almost] the same design in a database text book by elmasri and navathe

  5. says

    True, if he only asked for something else then me doing his homework.
    Logic problems are much more satisfying then copying.
