Pothole tracking and repair system (PHTRS)
The department of
public works for a large city has decided to develop a Web-based pothole
tracking and repair system (PHTRS). Citizens can log into a Web
site and report the location and severity of potholes. As potholes are reported
they are logged within 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 by 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 a 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 the citizen's name, address, phone
number, type of damage, and dollar amount of damage. PHTRS is a Web-based
system; all queries are to be made interactively.
