REQUIREMENT ANALYSIS AND MODELLING2
Introduction
Unified modeling Language also known as UML, is a very well-known modeling
language, which consists of a unified set of diagrams. It is mainly useful for the software
developers and the system to specify, visualize, construct and document the products of the
software system. It is also used for business modeling and for some other systems which are not
essentially software. Graphical notations are mostly used in order to express the software design.
In UML there are seven categories of structure diagram and seven types of behaviour diagram.
Structure diagrams are helpful because the systems can be represented in a static structured way,
with all the parts of the system at different abstraction level. It also helps to represent the
implementation of different parts of the system. Class diagram is an example of the structure
diagram. The behaviour diagrams are used to represent the dynamic behaviour of an object of a
system. Use case diagram, state machine diagram and sequence diagram are some examples of
behaviour diagram. In this report, a sequence diagram of the MakeOnlineReservation use case
has been explained. Also, a class diagram of the Booking system has been explained and the
state machine diagram of the Reservation process is also included.
Sequence diagram
The Stevenage Amateur Society (SADS) theatre, wants to implement a box office
subsystem (BOS) that will allow reservation of seats over the phone and the reservation will be
done by a box office staff. For this implementation a database and an internet connectivity is
required and the sequence diagram, shows the whole process of the reservation of seats, which
also allows the users to book tickets and make an online payment.
