Question $5$

Consider the case study that follows:

A small vehicle$/$car repair shop consists of two offices, an electronic workshop and two repair workshops. The shop employs many employees, and an employee works only for one shop. A job is done by many employees, and an employee performs many jobs. This relationship creates a challenge for the shop owner when he must analyze their working hours. The shop owner would like to have working hours as information of the employee as well as information for jobs done.

Some of the jobs are done by a group of engineers, and an engineer is assigned to many jobs. The engineers are either full time engineers or part time engineers. The following data should be stored about each engineer: Engineer number, Engineer name, Professional No$,$ Tel number. For full time engineer's Annual salary is also stored, while for part time Hourly rate and Hours worked are stored.

$5\mathrm{.}1$ To describe the above scenario, develop a domain class model class diagram. Assign attributes where necessary.
