Case Study- Milestone 1
A small surgery center needs your help to create a database. The office manager has
identified the following types of data (entities): patients, doctors, procedures and appointments
using the following business rules: Patients can have many doctors and many doctors can see
many patients. Patients can have many procedures and many procedures are done on patients.
Doctors can have multiple appointments. (hint: these are many to many relationships, so
associative tables need to be added).
Database Design
Primary Keys and Attributes
The primary keys will include, Doctor’s ID, Patients ID, and procedures ID, and
Appointment ID.
Data types for each entity
Patients entity – patients first and last names, name of kin, date of birth, postal address,
social security number, sex, contact number.
Doctor entity – Name of doctor, doctor work ID, area of specialty
Appointment entity – Appointment, name of doctor ID, patient ID, Date, Time.
Medical Procedure entity – Medical procedure ID, Order Number, Patient ID, doctor ID,
Treatment ID
Treatment entity – Treatment ID, Fee, type of treatment

The patient can have many doctors representing a many-to-many to one relationship. The
doctor can order several tests representing a one to many relationships. One doctor performs a
single procedure per patient making it a one to one relationship.This study source was downloaded by 100000838987296 from CourseHero.com on 01-20-2023 07:02:17 GMT -06:00

A strong database management system will positively affect management operations. It will
increase management workflows, operational intelligence, and also helps manage risk more
proficiently. A sturdy management system allows for quick and efficient action if ever anything
goes awry. Also, good data management helps show a clear picture of the framework of the
company. It will allow the team to cut processing time in half in many aspects of the business’
operations.
There are also database benefits to businesses using queries, forms and reports. The two
categories that would best benefit from that would be: accessing data and maintaining forms in
the database, and effective data management for business reports.This study source was downloaded by 100000838987296 from CourseHero.com on 01-20-2023 07:02:17 GMT -06:00

While there are positives and great sides to this, there are also security concerns to be
highlighted: we will need to use security applications, ensuring to keep systems up to date and
backing up the data to secure, encrypted cloud. A systems manager would handle the essentials
as it pertains to security concerns. Additional steps can be taken to ensure the server is secure,
timing password resets every 60-90 days, limiting access to the information based on levels of
security access. All data cannot be accessed by every single staff member.This study source was downloaded by 100000838987296 from CourseHero.com on 01-20-2023 07:02:17 GMT -06:00
