Task 2: System Design

Base on the requirement gathered in Task 1, answer the following

a. Draw a Use Case Diagram that highlights the security related interactions of the system amongst other interactions.
b. Keeping the case study in mind draw a UML Class Diagram focussing on the different access levels for each employee type. The diagram must contain the following – employee first name and last name, ID no, telephone no, address, date(s) present, date(s) on leave, hotel work zone and shift allocated”.

c. Since physical security is an important aspect of the security Auckland EZ hotel is highly concerned about each employee’s entry and exit from the building. To help develop such a secure system, map out a State Transition Network (STN) for the daily functioning of the attendance management part of the software. To scope the STN use the following assumptions

1. The starting state is when the employee enters the company first and the finish state is when the employee leaves finally for the day.
2. The attendance system is electronic and the employees have to tap their card on the card reader to register their entry and exit from the company.
3. Once the employee taps, an entry is made in a database table, this entry can be called ‘Employee In’

4. If the employee taps a second time the database entry is ‘Employee Out’.
5. An employee can tap in and out multiple times during the work hours of 9 am to 5 pm. The final exit for the day is considered at 5pm and total hours worked is calculated from the first tap to the last tap before or at 5pm.
6. If an employee has a gap of more than 1 hr between a tap in and out, they are reported to the HR
