Question description

PLEASE DO READ THE INSTRUCTION BEFORE BID , THANKS

Problem: Design an access card system for a building

This building requires access cards to enter its front door. A card reader will read the access card, get the card information, check whether the card has permission to enter, and then ask the cardholder to enter the password. If the card has permission and the corresponding password is correct, the card reader sends signals to open the door and records the time of entry. Otherwise, the card reader does not open the door and records the attempt as abnormal.

The cardholders include students, professors and technicians. Different types of cardholders have different card functions. The students only have basic functions: to access the building, and change their personal information (including passwords). The professors have the basic functions and can check the building entry information. The technicians have the basic functions; can check the building entry information, and give/cancel permissions to the student cards and professor cards. 


REQUIREMENTS :
1. Draw the design class diagram. In the diagram, include card holder class, student class, professor class, technician class, and/or other necessary classes. 

2. Draw the sequence diagram for the use case of "access the building".

Notes:

Draw a complete design class diagram with stereotype name and all applicable notations (e.g. visibility).

Use appropriate drawing software (e.g. Visio, Power point)
