Answer the following
Draw an activity diagram for the restaurant.
Suggest lactations where terminals would be required and other optional locations. Also mention how your suggestion would improve the functioning of restaurant. Draw a deployment diagram.

A local area network should be set up in the restaurant. A wireless network is preferable because in a wired network, the waiters would be jumping over wires to get to the terminals and sometimes may entangle with the laid down wires.

The network will improve communication between the waiter, chef and the busser. For example, communicating order from customer to chef, enquiring about the status of the meal preparation from kitchen etc. Also the waiter can send a message to the busser to come and clean table when a customer leaves.

Each busser and waiter will carry a terminal on his palm (palmtops). One desktop PC will be installed in the kitchen and another one in the manager‘s office. The chicken PC will store the databases namely the order database and the recipe database. Kitchen will have one or more screens for easy viewing all the chefs working there

When customer makes an order, the waiter could enter them into his palmtop and the order would go to the kitchen PC. This eliminates the time required to walk from the serving area to the kitchen to communicate orders. Also the waiter can ensure about the status of a meal pressing a button on the palmtop. The chef can reply to it providing an estimate of time required for the meal get ready.

When order is prepared, the chef can send a message to the waiter‘s palmtop. The waiter can then come and collect the meals. This eliminates the time required for repeatedly coming to the kitchen to check whether the order is ready or not

The kitchen and manager‘s PC are connected to a printer. Each serving area will have a printer so
that the waiters can print bills without having to walk to the cash collecting counters

Since the kitchen is away from the Manager‘s office, a repeater is placed between so that the signals do not get attenuated with distance.
The deployment diagram is shown in figure 2.
