This graphic shows a circle on the left labeled "Client." It points to a pentagon 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 pentagon are two more pentagons. They are identical. They each have three labels: "Servlet" and "Objects" are on top. "ABC" is under "Objects."

All three pentagons point to a database.
