2.1

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),zip
Code:integer (5))
2.1) (4 Points) Write SQL statements to create the Treatment and Specialty table. Make sure to include
entity integrity and referential integrity constraints (if any) in your statements. Only need the create
statement for the Treatment and Specialty table, not the rest.
2.2) (2 Points) Devise a reasonable database instance by filling the tables with reasonable data of your
