Please follow this ER diagram, give a description, and make a schema diagram from it. Also, make database (constraint tables) & intent some sample data. Lastly, run some SQL functions code. Please don't copy from anywhere. I need it for my project.
Answer questions 2.1 to 2.4 based on the following schema. Note that primary keys are in BOLD. Note also that attributes with the same name in different tables are foreign keys. For example, doctorID in the Treatment table is a foreign key that refers to the Doctor table. Doctor(doctorId:integer, specialtyID:integer, firstName:varchar(20), lastName:varchar(20), salary:numeric(11,2)) Specialty(specialtyID:integer, specialtyName:varchar(20), specialtyCost:numeric(11,2)) Treatment(doctorId:integer, patientSSN:integer, dateTreated:date, costOfTreatment:numeric(11,2)) Patient(patientSSN:integer, firstName:varchar(20), lastName:varchar(20), street:varchar(30), city:varchar(15), state:char(2),zipCode:integer(5)) 1. Write an SQL statement to increase the cost of all Specialty treatment by 2.5% 2. Write a SQL statement to delete all treatment rows that were done before 2015 and cost less than $500.
