1 Goal of Project
The project is to create a mini world of a hospital and the various entities in it. These are are; patients, doctors, nurses, medical labs,
scientists, lab tests, lab reports, diagnosis test, Treatments and billing among other data. Once these are created it wish to gain
experience using MySQl to create and modify the database system using several commands and print a report based on successes of
these commands.
1.1
Project Description
A patient is admitted into a hospital at a specific date. This hospital is in a region close to where the patient lives. This patients
address has its name and address key (primary key). Each hospitals is managed by staff(scientists, doctors, nurses) who have their
own staff id and has a maximum recommended capacity. In the hospital one is either a patient or a staff member. A hospital contains
different wings and has a number of them. A wing has a set maximum patient capacity and a wing id(primary key) however. Each
patient is assigned to a wing in the hospital. A patient's personal records are stored separately from their hospital specific and
includes Name Address, age MCP number, email address and phone number.
The hospital staff are either lab scientists, doctors or nurses. All staff are grouped by categories of role.
A doctor is assigned one or more patients, is identified by their name, doctor id(primary key) which references their staff id in the
general system. A doctor also has an area of speciality, even if that area is general. This doctor consults a medical lab identified by its
Wing id -which is the primary key), lab id and name about a patient.
Each lab is run by lab scientists who have their own name, scientist_id(primary key) which references their staff id in the general
system and lab they work in.
The lab runs a diagnostic using tests. These tests can be anything and there can be more than one been run and they are performed by
lab scientists within a specific medical lab. These diagnostics are identified by a patient who it is for a test id and also include a
reference which has comments by that lab scientist including its own diagnostic id as a primary key. The diagnostics are compiled
into reports based on report id, name, diagnostic id, lab name, Treatment name and date. These reports are requested by doctors and
the patient is shown information it contains. A treatment id maps to specific recommended treatments for the patient (there may be
more than one).
While the patient is admitted they are assigned a room and therefore the who attends to them in their hospital room. Each patient
room is specified by a floor, patient id (primary key) and room id(primary key). Patient personal records such as age, sex, address,
email address and phone number including patient id are stored about a patient separately from information about their admittance
to the hospital.
The nurse is specified by a name, nurse id(primary key) which references their staff id in the general system. Nurses are assigned to
patient rooms and each room can have multiple nurses attending to it. Each medical test is specified by the lab location, and
test_id(primary key) who is running such test and name of the test. All staff take shifts in the hospital and have a start time and
number of hours they usually attend to and that includes the shift id numbers. Each staff also had staff records associated with them.
The records include:
staff id(primary key), address, pay-class, birth date, sex, MCP number, phone number, email.
All staff in the hospital are assigned a wing.
A patient their bill. The bill has a name and amount associated with it.

Experiences
As this was my first time using MySQL I had trouble getting the syntax correct for a lot of my commands, i received many
errors when entering, manipulating the updating my database. The following are a collection of these such errors:
mysql> alter table Staff_Recordss add primary key(staff_id);
ERROR 1146 (42S02): Table 'hospital_project.staff_recordss' doesn't exist
mysql> alter table Staff_Records add primary key(staff_id);
Query OK, 0 rows affected (0.11 sec)
mysql> alter table Staff_Records add foreign key(staff_id) references Staff(staf
f_id);

As a whole using the internet, particularly w3schools.com , roseindia.net and stackoverflow.com i was able to learn the
mysql constraints and syntax for correcting using the database structure.
1.3
Analysis, summarizations and conclusions
Overall the database designed is very robust and while it does not cater the entire needs of a typical hospital is a well formed template
of such a type of entity. The description and EER diagram of my database had to be adopted several times in my project to remove
redundancies and several present constraints in the database.
