base stores information about houses, each with a house ID, address, and zip code. The database stores information about person, including person ID, house ID where the person lives, person name, phone number, and status where 1 means currently tested positive (i.e., the most recent test result is positive), 0 means currently tested negative (i.e., the most recent test result is negative), and null (no test so far so status is unknown). The database stores information about a person's all past tests, including person ID, test date, and result (1 means positive and 0 negative).
