DBST 651, FALL 2016
Overview:
I will create a database to keep track of patient data for a medical facility. This database will aid
in easing the flow of operations at a medical facility and provides immediate information to
doctors and nurses regarding the condition of a patient
Purpose and Objective:
The database will enable a nurse to enter and store a patient charts and histories during a
particular trip to the clinic. It stores the patient’s first and last name, age, symptoms,
prescriptions for the patient, and the date the patient is admitted into the clinic. This database
also keeps track of the doctors and nurses that attend to a particular patient as well as the patient
diagnosis from the doctor. The charts from the nurse is used to update the doctor on the condition
of the patient which in turn assists the doctor(s) in performing adequate diagnosis. The
information stored in this database would be used to efficiently track the patients that are treated
at the clinic, the nurse charts and history of patient’s symptoms, the doctors’ diagnosis of the
patient and the date a patient gets admitted and checked out of the clinic.
Diagram Tool:
ER Assistant
Database:
Oracle 11g, using Virtual Desktop Applications (VDA)
Hardware and Software:
UMUC (VDA) Intel(R) Core(TM). Operating system is Windows
DDL and DML:
SQL (Structured Query Language) will be used to create the DDL and DML scripts. SQL would
be used to translate the information captured using the ER Assistant, in an ER diagram, into
3. database table creation scripts for my DDL scripts. This diagram contains the various entities,
attributes and relationship that exist in this database. SQL would also be used to insert rows of
data or record into the database tables for my DML scripts. It would also be used to retrieve or
update a record

Entity Relationship
Relationship: works between PATIENT and PRESCRIPTION
6. Cardinality/Business rule: a patient can receive zero to many prescriptions, a prescription is received by
one and only one patient
Relationship: works between DOCTOR and PATIENT
Cardinality/Business rule: a doctor can treat zero to many patients, a patient gets treated by one and
only one doctor
Relationship: works between DOCTOR and PRESCRIPTION
Cardinality/Business rule: a doctor can prescribe zero to many prescriptions, a prescription gets
prescribed by one and only one doctor
Relationship: works between NURSE and ASSIGNMENT
Cardinality/Business rule: a nurse can have zero to many assignments, an assignment is reserved for
one and only one nurse
Relationship: works between DOCTOR and ASSIGNMENT
Cardinality/Business rule: a doctor receives assistance from zero to many assigned nurses, an assigned
nurse provides assistance to one and only one doctor
Assumptions
1. A patient is only assigned one doctor throughout the duration of stay at this hospital
2. There is a cap at how many nurses can get assigned to a doctor at any time (maximum is 4).
3. The Assignment_Cap attribute in Assignment entity checks this value. If valid, then assignments
can be made
