A city transportation department wants to develop a computer-controlled roadmanagement and maintenance system (PMTRS). When a road is constructed, the system assigns an identification number to the road and stores its street address, size(on a scale of 1 to 10), location (in the road, on the sidewalk, etc.), neighborhood it belongs to (derived from the street address), and road priority (determined by its class). If damage occurs to the road, creating a roadblock, a work order is issued for each road, including the location, size, crew number,number of workers, number of tools equipped, number of man-hours to repair, status of the roadblock (under construction, repaired, temporarily repaired, notrepaired), amount of materials used, and cost of maintenance (calculated based on repair man-hours, number of workers, materials and tools, etc.). Finally, thesystem creates a damage report file that records the damage caused by this roadblock, including the citizen's name, address, phone number, type of damage, and the amount of damage (in dollars). PMTRS is an online system that can be accessed at any time. Inquiries are available to the user. 3.1 Using the UML modelling language, give a representative use case diagram for this case. (10 points) 3.2 Draw a class diagram of the system. (10 points) 3.3 Design a system architecture diagram for the system (the main functions included in the system). (10 points)< 3.4 Given a sequence diagram of this system, explain the functions completed by the sequence diagram. (10 points)
