The map of California is divided into square mile gridcells, each with a lower left x and y GPS coordinate. The Fire System maintains a num ber of Basestations, each has a nickname that may not be unique, and is located inside a gridcell. No gridcell has more than one Basestation. For each Basestation we keep lists of the tools and equipment based there. Each person in the database is given a pager with a unique number. We also record his or her lastname and firstname. Each Firefighter gets a unique FID and may be assigned to a basestation. Each Inspector gets a unique IID. Some Firefighters also act as Inspectors. When a fire touches 4 or more gridcells, it is categorized as a Wildfire and assigned a unique WFID and start-date. A gridcell can contain up to 2 wildfires. Each wildfire is assigned at least 8 Firefighters and no Firefighter can be assigned to more than 3 Wildfires. Whenever an Inspector inspects a Wildfire, we record the date and number of acres damaged. Design an EER Diagram with exactly 5 Regular Entity Types (including sub- classes), 1 Weak Entity Type, and 5 Relationship Types (including weak en- tity relationships). Clearly label primary and partial keys and (max,min) constraints. List any additional assumptions you need.
