USE CASES
1. Draw a use case diagram for a ticket distributor for a train system.
The system includes two actors: a traveler who purchases different
types of tickets and a central computer system that maintains a

BuyOneTicket, BuyWeeklyCard and UpdateTariff. Also include the
following exceptional cases Timeout(i.e. traveler look too long to
insert the right amount), TransactionAborted (i.e. traveler selected the
cancel
button
without
completing
the
transaction),
DistributorOutOfChange, and DistributorOutOfPaper.

ACTIVITY DIAGRAM
1. Consider a process of ordering a pizza over the phone. Draw an
activity diagram representing each step of the process, from the
you pick up the phone to the point where you start eating the
pizza. Do not represent any exceptions. Include activities that
others need to perform.

STATE TRANSITION DIAGRAM
1. Draw STD for an “Order Processing System”.
2. Consider a traffic light system at a four Way cross roads (two roads
intersecting at Right angles. Assume the simplest algorithm for cycling
through the lights (example: all traffic on one road is allowed to go
through the cross road, while the other traffic is stopped). Identify the
states of this system and draw a state chart describing them. Remember
that each individual traffic light has three states (Green, Yellow, Red).

DEPLOYMENT DIAGRAM
Consider a system that includes a webserver and two database
servers. Both database servers are identical: the first acts as a main
server, and the second acts as a redundant backup in the case the first
one fails. The users use web browsers to access data through the web
server. They also have the option of using a proprietry client that
accesses the database directly. Draw a UML deployment diagram
representing the hardware/ software mapping of the system.
