Example File Structures

When describing file structures
  • use a large box to represent a page
  • use either a small box or tupi (or reci) to represent a tuple
  • sometimes refer to tuples via their key
    • mostly, key corresponds to the notion of "primary key"
    • sometimes, key means "search key" in selection condition
