  processes and displays HTML resources.
• The browser sends HTTP requests to the middle
  tier, and then the middle tie does the following
  works it drives the structure and the content of
  the data displayed to the user, and it processes
  input from the user as it is formed into queries
  on the database to read or write data.
• When the middle tier sends the query to the
  database tier, the database tier manages the
