This graphic shows a "Client" on the left. It points to a box with four labels: "Servlet" and "Objects" are on top. "User Interaction" is under "Servlet" and they are connected by a line. "ABC" is under "Objects". "User Interaction" and "ABC" are connected by two lines.

Under the box are two more boxes. They are identical. They each have three labels: "Servlet" and "Objects" are on top. "ABC" is under "Objects".

All the three boxes point to a database.
