Refer to the case study given below, draw Sequence Diagram and Class Diagram? Also compare the information depicted by both diagrams and state scenario in which conditions you have to have sequence diagram or Class Diagram? Our aim is to design a CUI Transport system. It mainly facilitates drivers, students and faculty regarding bus tracking. Students need to register themselves through an online portal. In case buses are leaving early someday, everyone gets notified about the situation. Students can easily locate exact location of buses through their mobile application via GPS and the distance and estimated time of arrival of bus to their stop. Chat box is also available for issue reporting and communication between drivers, students and faculty members. System Admin can edit and delete the data of students and drivers. He can view all the bus expenses and charges. Administrator is responsible for maintaining the system and will be involved in regular maintenance and updating the records. Students are an important stakeholder as they are the ones who would access the system online. Students preferred language is English. Students have more technical knowledge and can easily understand the system. Drivers might have little knowledge about the application and how to check and update the records of the buses status
