Each illness has a name and some medicines or other treatments commonly prescribed (e.g., certain type of counseling). Each participating agency is of a certain type (e.g., criminal justice, mental health) and has a name and a contact person. People visit or contact an agency (e.g., they are arrested by the justice system or stay at a shelter). For each contact a person has with an agency, the database needs to record the contact date, employment status at time of contact, address at time of contact, reason for visit/contact, and the name of the responsible agency employee.

Explain
Draw an ERD for the following situation, which is based on Lapowsky
(2016): The Miami-Dade County, Florida, court system believes that
jail populations can be reduced, reincarceration rates lowered, and
court system costs lessened and, most important, that better
outcomes can occur for people in and potentially in the court system
if there is a database that coordinates activities for county jails, metal
health facilities, shelters, and hospitals. Based on the contents of this
database, algorithms can be used to predict what kind of help a
person might need to reduce his or her involvement in the justice
system. Eventually, such a database could be extensive (involving
many agencies and lots of personal history and demographic data)
once privacy issues are resolved. However, for now, the desire is to
create a prototype database with the following data. Data about
persons will be stored in the database, including professionals who
work for the various participating agencies as well as those who have
contact with an agency (e.g., someone who is a client of a mental
health facility, who is incarcerated, or both). Data about people
include name, birth date, education level, job title (if the person is an
employee of one of the participating agencies), and (permanent)
address. Some people in the system will have been prescribed certain
medicines while in the care of county hospitals and mental health
facilities. A medicine has a name and a manufacturer. Each
prescription is for a particular medicine and has a dosage. A
prescription is due to some diagnosis, which was identified on a
certain date, to treat some illness, was diagnosed by some facility
professional, and has notes explaining family history at the time of the
diagnosis. Each illness has a name and some medicines or other
treatments commonly prescribed (e.g., certain type of counseling).
Each participating agency is of a certain type (e.g., criminal justice,
mental health) and has a name and a contact person. People visit or
contact an agency (e.g., they are arrested by the justice system or stay
at a shelter). For each contact a person has with an agency, the
database needs to record the contact date, employment status at
time of contact, address at time of contact, reason for visit/contact,
and the name of the responsible agency employee.
