8.5 The department of public works for a large city has decided to develop a Web-based pothole tracking and repair system(PHTRS). Draw a UML use case diagram for the PHTRS system. You’ll have to make a number ofassumptions about the manner in which a user interacts with this system. A description follows:

Citizens can log onto a website and report the location and severity of potholes. As potholes are reported they are logged with a “public works department repair system” and are assigned an identifying number, stored by street address, size(on a scale of 1 to 10), location(middle, curb, etc.),district(determined from street address), and repair priority(determined from the size of the pothole). Work order data are associated with each pothole and include pothole location and size, repair crew identifying number, number of people on crew, equipment assigned, hours applied to repair, hole status(work in progress, repaired, temporary repair, not repaired), amount of filler material used, and cost of repair (computed from hours applied, number of people, material and equipment used). Finally, a damage file is created to hold information about reported damage due to the pothole and includes citizen’s name, address, phone number, type of damage, and dollar amount of damage, PHTRS is an online system; all queries a to be made interactively.

1. UML use case

8.6 Write two or three use cases that describe the roles of various actors in the PHTRS .

Case 1: filling situation

Participants: Citizens

    when citizens log in to phtrs, they input their account number, and they input two passwords (each at least 8 characters in length). The system displays all the main function buttons. Citizens select “fill in” from the main functions. Citizens fill in the street address, size, location, region, and repair priority. Citizens choose to save. The system assigns an identification number for the fill in and generates an order to be sent to the public works department Staff

Case 2: fill in the worksheet

Participants: construction workers

    when the construction personnel log in phtrs, the construction personnel input the account number, the construction personnel input two passwords (each with a length of at least 8 characters), the system displays all the main function buttons, the construction personnel select “fill in the worksheet” from the main functions, the system displays the work order assigned by the construction personnel, the construction personnel select the corresponding work order, the construction personnel fill in the number of personnel, and the allocated equipment, Repair time, pothole state, filling materials, repair cost and other information submitted by construction personnel

    8.7 Develop an activity diagram for one aspect of PHTRS.

    2. The activity chart of the construction personnel filling in the work sheet

    8.8 Develop a swimlane diagram for one or more aspects of PHTRS.

    3. The construction personnel fill in the swimlane chart of the work sheet
