Part 1
class diagram
Class diagrams are UML diagrams used to model the static structure and the
dynamic structure of a system. To model a system using an analysis class diagram
objects making up the system have to be identified (Ambler, 2014). Each object can
be modelled as a class to make up the class diagram. A class is identified by
attributes which become variables and behaviors which become methods when the
class is modelled. Classes are related though different techniques including
inheritance between parent classes and child classes, aggregation and composition.
Class diagrams are important while modelling a system using UML (microTOOL,
2018).
Class diagrams are very important in system analysis because they are the heart of
UML. Class diagrams are modelled on the basis of object orientation thus can be
used in different phases of a project. In the analysis stage of a project, class
diagrams act as the domain model by creating a representation of the real world.
During the design and implementation phase, class diagrams can be applied for
generation of source code.

Decisions
 A tour has one or more itineraries. An itinerary can be an event that are held
in different stages of the tour or in different venues that visited during the
tour.
 Each tour is assigned or more drivers. A tour cannot happen without a driver.
