Online Health Monitoring System
Introduction
Healthcare has witnessed a massive transformation with the advancement in technology and there are
new web-based applications that are being developed. These applications have succeeded in
enhancing the quality and accuracy of health care services along with the health conditions of the
patients. One such application is online health monitoring system. The system will allow easy
monitoring of blood pressure, heart rate, and other health signs to remotely manage and maintain the
health. It will be integrated with the latest technologies, such as Internet of Things (IoT) and will be
capable of electronic records maintenance. Rapid Application Development (RAD) is the software
development methodology that will be followed in the design and development of the system and the
project will be managed used Project Management Body of Knowledge (PMBOK) as the project
management methodology.
The report covers the details of project implementation, project testing along with the critical
evaluation measures that shall be followed.
Project Implementation
There will be different stages that will be present in the implementation phase of the project. These
stages will include coding, database development, and interface design. The implementation phase of
the project will continue for 7-8 weeks and the details of the implementation are described below.
System Architecture
The system architecture that will be involved with the online health monitoring system will be a
multi-tier architecture.
The first tier of this system will include the interface for the patients. This interface will include a
series of wearable sensors in order to gather the medical and health information from the patients. It
will be necessary to ensure that the data of the health conditions of the patients is recorded in real-
time and is sent over to the medical team on an immediate basis. The system will allow the movement
of the data sets wirelessly with the aid of Bluetooth low energy. The second tier of the system, that is
an Android smartphone or a tablet will now come in to the picture. The Android enabled device will
extract the data sets as transferred from the wearable device and will be enabled with an inbuilt
wireless networking. This will allow the data to be shared on the web portal through any of the
mediums, such as Wi-Fi networks, GPRS, and likewise. The GPS technology present in the Android
enabled device will also keep a track of the location of the patients. The third tier of the system will
make use of SQLite and online MySQL as the database engines. The web portal will extract the data
and information sets from its internal database in the form of SQLite database engine. This will then

be transferred to the online MySQL database for data storage, analysis and processing. The Wi-Fi
network will be used for the transfer of the data. The web portal will combine the data sets collected
from the patients and will display the same on the web interface which will be an interface for the
medical professionals. The location along with the demographic details of the patients will also be
showcased. The wearable devices available with the patients will be able to record the blood pressure,
heart rate, blood sugar and body temperature of the individuals. The system architecture that will be
used in the system has been illustrated in the figure below.
System Architecture (Kakria, Tripathi and Kitipawang, 2015)
The proposed system architecture will have the capability to make use of multiple sensors in order to
record the health signs of a large number of patients. The ability to use these sensors at the same time
will allow a simultaneous monitoring of the overall health condition and will also enhance the
accuracy of the results. The primary aim of the system is to develop a real-time system for providing
timely care to the patients.
Heart rate is one of the basic health sign that is required to be regularly monitored in a majority of
health conditions. The alterations in the heart rate can signify an abnormal physical condition or a
medical disorder as well. The wearable sensor that is used in the system will allow regular and real-
time monitoring of the heart rate. The system will also keep a track of the history of the heart rate of
every patient so that the monitoring of the health condition may be done with ease and accuracy
(Harsha, 2014).
Zephyr BT is one of the most popular wearable sensors for recording the heart rate of the patients and
the same will be integrated in the online health monitoring system in this case. The selection of the
same has been made as per the performance, usability, and cost that are associated with the sensor.
Bluetooth low energy allows the sensor to be durable and to be used with utmost accuracy. The sensor
is compatible with the latest Android versions and, therefore, will be integrated with the Android
smartphones and tablets being used in the current times.
Blood pressure, blood sugar, and body temperature are the other health signs that are necessary to
detect the physical condition and fitness of a patient. In case of a medical disorder or a physical
condition, there is an alteration in any of these parameters that is witnessed. The medical team and

professionals record these signs to understand the possible health conditions that may be present. The
system will allow the real-time recording and monitoring of these health signs which will assist the
medical team in the diagnosis and treatment processes.
Database Development
SQLite
The internal database for the web portal will be SQLite for data storage and management. The
database engine will offer numerous benefits to the online health monitoring system as it will include
the following set of features.
 There is no configuration or installation required with SQLite and there is also no
administrator required for develop a new instance. The database works without such set-ups.
 There is no server process involved in SQLite and the entities that wish to access the database
read and write directly from the disk. It also allows multiple applications to simultaneously
access the database (Sqlite, 2018).
 The database makes use of a single database file and can be directly access from the directory
hierarchy. There is no additional file management involved in the database which makes it
easy to use.
 The database makes use of manifest type instead of static typing.
 Variable length records can be stored in the database.
The features that are stated above will ensure that the required data sets can be efficiently stored in the
online health monitoring system. The patient records may include structured or unstructured data of
varied data types that will be possible to store easily on the web portal to allow it to be transferred to
the medical team for analysis.
Online MySQL
The online health monitoring system will have huge data requirements as there may be hundreds and
thousands of patient records that may be stored and processed in a single day. Also, every patient will
have a corresponding medical history along with the medical reports. In order to store and process
such huge clusters of information, it would be necessary to make use of cloud database.
MySQL is a database engine that will offer cloud data storage with its online data storage, processing
and management abilities. There will be several advantages that will be offered by online MySQL to
the online health monitoring system in terms of excellent performance and scalability, rapid
connection handling, auto-sharding, enhanced security and availability (Oracle, 2011).
The back-up and recovery options that are provided by online MySQL are also abundant. These
options will make sure that the patient and medical data is always secure (Mysql, 2018).
