$7$: Modelling UML $(20$ points$)$

You have to organize the operational planning of a road construction company. Create an UML

model that is capable of representing the information described below. Remember to include all at$-$

tributes with respective types.

Please note that if the following descriptions are not entirely unambiguous $($sometimes there may be

more than just one way to model our real world$),$ be sure to briefly justify your design decisions.

a$)$ The company $($the company itself does not have to be modelled$)$ is organised in teams. These

teams consist of one leader and $3$ to a maximum of $9$ workers, while the leader may lead $1$ or $2$

teams.

For the leaders and the workers, the given name, surname, street, house number and telephone

number have to be represented. For the leader, an annual salary has to be stored. However, for a

worker we need to store its day of birth $($dob$)$ and his filed of specialization $($for instance wood,

cement, metal$).$ For the team itself, a bonus $($amount of extra money$)$ should be stored. If a team

is being dissolved $($for instance due to reorganisation of the teams$),$ it has to be an impact on the

leader and the worker in the subsequent data storage. $(8$ points$)$
