1. Introduction
1.1) Purpose
The Software is for the automation of Hospital Management.
It maintains one levels of user:-
Administrator Level
The Software includes:-
Maintaining Patient ‘s details.
Maintaining Doctor’s details.
Maintaining Room records.
Bill generation.
1.2) Scope
It can be used in any Hospital, Clinic and Dispensaryfor maintaining
patient details.
1.3) Relevant Tools and Technologies
This chapter presents some discussions about the relevant tools and technologies
used to develop the e-commerce web application. Some of the tools and
technologies are Java programming language, JDK and JRE, MySQL and
Netbeans IDE.
1.3.1 Java Programming Language
This is the main programming language used to develop the application. The Java
Programming Language was formerly developed by Sun Microsystems as
proposedbyJames Gosling. It was first released in 1995. It runs on Mac OS,
Windows, the different versions of UNIX, and other platforms. Java is considered
to be secure and robust. Also, it is multithreading and platform independent (unlike
C and C++)
1.3.2 JDK and JRE
The Java Development Kit (JDK) is a software development environment for
developing applets and applications written in Java. It consists of an interpreter, a
Java compiler, a documentation generator (JavaDoc) and several other tools for
building Java applications. The Java Runtime Environment is a component of JDK,
and it consists of the Java Virtual Machine (JVM), libraries, files and other

components for running applications written in Java. JVM is an implementation of
JRE for running Java bytecode.
1.3.3 MySQL
MySQL is a free, open source relational database management system (RDBMS)
that supports Structured QueryLanguage(SQL).An RDBMS is a system used to
manage databases, and it is made up of tables containing columns and rows, where
the tables are related by keys. MySQL DBMS is the world’s most popular open
sourcedatabase system and one of the most commonly used database systems for
Java web applications. It is one of the fastest RDBMS and it is easy to use. Also, it
runs on almost all platforms, such as Windows, Linux and OS X.
1.3.4 Netbeans IDE
Netbeans is an integrated development environment (IDE) for Java Netbeans
allows applications to be developed from a set of modular software components
called modules. Netbeans runs on Windows, macOS, Linux and Solaris. In
addition to Java development, it has extensions for other languages like PHP, C,
C++ and JavaScript. Applications based on Netbeans, including the Netbeans IDE,
can be extended by third party developers. The latest release of Netbeans is
Netbeans IDE 10.0, which was released in December 2018.

 Maintaining records of doctors registered with the hospital/clinic.
 Providing billing details for indoor/outdoorpatients.
 Maintaining details of users logging in.
. Administrator can search a patient’s record.

2. Overall Description
2.1) Goals of proposed system
1. Planned approach towards working: - The working in the
organization will be well planned and organized. The data will be stored
properly in data stores, which will help in retrieval of information as well as
its storage.
2. Accuracy: - The level of accuracy in the proposed system will be
higher. All operation would be done correctly and it ensures that whatever
information is coming from the center is accurate.
3. Reliability: - The reliability of the proposed system will be high due to
the above stated reasons. The reason for the increased reliability of the
system is that now there would be properstorage of information.
4. No Redundancy: - In the proposedsystem utmost care would be that
no information is repeated anywhere, in storage or otherwise. This would
assure economic use of storage space and consistencyin the data stored.
5. Immediate retrieval of information: - The main objective of
proposed system is to provide for a quick and efficientretrieval of
information. Any type of information would be available whenever the user
requires.
6. Immediate storage of information: - In manual system there are
many problems to store the largest amount of information.
7. Easy to Operate: - The system should be easy to operate and should
be such that it can be developedwithin a short period of time and fit in the
limited budget of the user.

2.2) Background
A Hospital is a place where Patients come up for general diseases.
Hospitals provide facilities like:-
Consultation by Doctors on Diseases.
Diagnosis for diseases.
Providing treatment facility.
Facility for admitting Patients (providing beds,nursing, medicines etc.)
Immunization for Patients/Children.
Various operational works that are done in a Hospital are:-
Recording information about the Patients that come.
Generating bills.
Recording information related to diagnosis given to Patients.
Keeping record of the Immunization provided to children/patients.
Keeping information about various diseases available to cure them.
These are the various jobs that need to be done in a Hospital by the
operational staff and Doctors.All these works are done on papers.
The work is done as follows:-
Information about Patients is done by just writing the Patients name, age
and gender. Wheneverthe Patient comes up his information is stored
freshly.
Bills are generated by recording price for each facility provided to Patient
on a separate sheet and at last they all are summed up.
Diagnosis information to patients is generally recorded onthe document,
which contains Patient information. It is destroyed after some time period to
decrease the paper load in the office.
Immunization records of children are maintained in pre-formatted sheets,
which are kept in a file.
Information about various diseases is not kept as any document. Doctor
themselves do this job by remembering various medicines.
All this work is done manually by the receptionistand other operational staff
and lot of papers are needed to be handled and taken care of. Doctors
have to remembervarious medicines available for diagnosis and
sometimesmiss better alternatives as they can’t rememberthem at that
time.

2.3) Current Management System
Most hospitals face several challenges with Hospital Management
System because some of them are still using manual processes, while the
ones that use the computerized method are also faced with the challenge
of adjusting to it. Such problems include:
High cost of software development, deployment and improvement.
Difficulty in migrating from manual processes, because both staff and
patients are used to the manual processes and so are unable to speedily
cope with the new system.
Lack of IT friendly medical personnel is also presenting several
challenges.
Huge influx of patients visiting government hospitals makes the
process of migrating to automated processes highly difficult. They do
not have the patience to wait for registration and data entry and often fail
to understand the functioning of automated processes.
Considering the above, there is need for the improvement of
computerized hospital management system to such hospitals as it would
help provide and customize clinical data, enable faster diagnosis with
ready-made templates, allow doctors to follow advanced medical
prescription patterns, and so on.

2.4) Project Requirements
Hardware Requirements
Processor RAM Disk Space
Pentium IV or
higher
64 MB or higher 150 MB
Software Requirements
Operating System Database
Win- 07 , Win -10 or any other
higher version
MySQL 5.1 or higher
Table 1: Project Requirements
2.5) User Characteristics
Every user should be:
Comfortable to work on computer.
He must have knowledge in medical field.
He must also have basic knowledge of English too.
2.6) Constraints
GUI is only in English.
Login and password is used for identification of user and there is no
facility for guest.

2.7) Definitions of problems
Problems with conventional system
1. Lack of immediate retrievals: -The information is very difficult to
retrieve and to find particular information like- E.g. - To find out about the
patient’s history, the user has to go through various registers.This results
in inconvenience and wastage of time.
2. Lack of immediate information storage: - The information
generated by various transactions takes time and efforts to be stored at
right place.
3. Lack of prompt updating: - Various changes to information like
patient details or immunization details of child are difficultto make as paper
work is involved.
4. Error prone manual calculation: - Manual calculations are error
prone and take a lot of time this may result in incorrect information. For
example calculation of patient’s bill based on various treatments.
5. Preparation of accurate and prompt reports: - This becomesa
difficult task as information is difficultto collectfrom various registers.
2.8) Alternative Solutions
1. Improved ManualSystem:-
One of the alternative solutions is the improvement of the manual system.
Anything, which can be done by using automated methods,can be done
manually. But the question arises how to perform thing manually in a sound
manner. Following are some suggestions,which can be useful in the
manual system.
A more sophisticate register maintenance for various Patient Information,
Doctordiary, Immunization Details and a good system for writing bill

amount employees and stock availed for the customers can be maintained
at central place.
Adequate staff may be maintained so that updates are made at the very
moment at the same time. Properperson for properwork should be made
responsible so that a betterefficiencycould be achieved. This needs a lot
of work force.
2. Batch System:-
Another alternative solution can be used of computerbased batch system
for maintaining the information regarding purchase details, customers and
employees.A batch system refers to a system in which data is processed
in a periodicalbasis.
The batch system is able to achieve most of the goals and sub goals. But a
batch system data is processed in sequential basis. Therefore batch
system is not suggested.
3. Online System:-
This system (HMS) provides online storage/updates and retrieval facility.
This system promises very less or no paper work and also provides help to
Doctorand operational staff.
In this system everything is stored electronically so very less amount of
paperwork is required and information can be retrieved very easily without
searching here and there into registers.This system is beendiscussed
here.
3. Feasibility Study
Depending on the results of the initial investigation the survey is now
expanded to a more detailed feasibility study. “FEASIBILITY STUDY” is a
test of system proposalaccording to its workability, impact of the
organization, ability to meet needs and effective use of the resources.It
focuses onthese major questions:
1. What are the user’s demonstrable needs and how does a candidate
system meet them?
2. What resources are available for given candidate system?
3. What are the likely impacts of the candidate system on the organization?
4. Whether it is worth to solve the problem?

During feasibility analysis for this project, following primary areas of interest
are to be considered.Investigation and generating ideas about a new
system does this.
Steps in feasibility analysis
Eight steps involved in the feasibility analysis are:
Form a project team and appoint a projectleader.
Prepare system flowcharts.
Enumerate potential proposedsystem.
Define and identify characteristics of proposedsystem.
Determine and evaluate performance and costeffective of each
proposed system.
Weightsystem performance and costdata.
Selectthe best-proposed system.
Prepare and report final project directive to management.
3.1) Technical feasibility
A study of availability of resources that may affectthe ability to achieve an
acceptable system.This evaluation determines whether the technology
needed forthe proposed system is available or not.
Can the work for the projectbe done with current equipmentexisting
software technology& available personal?
Can the system be upgraded if developed?
If new technologyis needed then what can be developed?
This is concerned with specifying equipmentand software that will
successfullysatisfy the user requirement. The technical needs of the
system may include:
Front-endand back-end selection
An important issue for the developmentof a project is the selectionof
suitable front-end and back-end. When we decided to develop the project
we went through an extensive study to determine the most suitable
platform that suits the needs of the organization as well as helps in
developmentof the project.
The aspects of our study included the following factors.

Front-endselection:
1. It must have a graphical user interface that assists employees that are
not from IT background.
2. Scalability and extensibility.
3. Flexibility.
4. Robustness.
5. According to the organization requirement and the culture.
6. Must provide excellent reporting features with good printing support.
7. Platform independent.
8. Easy to debug and maintain.
9. Event driven programming facility.
10. Front end must supportsome popular back end like MySQL.
According to the above stated features we selected Netbeans IDE 6.5.1 as
the front-end for developing our project.
Back-endSelection:
1. Multiple user support.
2. Efficientdata handling.
3. Provide inherent features for security.
4. Efficientdata retrieval and maintenance.
5. Stored procedures.
6. Popularity.

7. Operating System compatible.
8. Easy to install.
9. Various drivers must be available.
10. Easy to implant with the Front-end.
According to above stated features we selected MySQL as the backend.
The technical feasibility is frequently the most difficultarea encountered at
this stage. It is essentialthat the process ofanalysis and definition be
conducted in parallel with an assessmentto technical feasibility. It centers
on the existing computersystem (hardware, software etc.) and to what
extent it can supportthe proposed system.
3.2) Economical feasibility
Economic justification is generally the “Bottom Line” considerationfor most
systems.
Economic justification includes a broad range of concerns that includes
costbenefit analysis. In this we weight the costand the benefits associated
with the candidate system and if it suits the basic purpose of the
organization i.e. profit making, the project is making to the analysis and
designphase.
The financial and the economic questions during the preliminary
investigation are verified to estimate the following:
 The costto conducta full system investigation.
The cost of hardware and software for the class of application being
considered.
The benefits in the form of reduced cost.
The proposedsystem will give the minute information, as a result the
performance is improved which in turn may be expected to provide
increased profits.

This feasibility checks whether the system can be developedwith the
available funds. The Hospital ManagementSystem does not
require enormous amount of money to be developed.This can be
done economicallyif planned judicially, so it is economicallyfeasible.
The cost of projectdepends uponthe number of man-hours required.
3.3) Operational Feasibility
It is mainly related to human organizations and political aspects.The points
to be consideredare:
What changes will be brought with the system?
What organization structures are disturbed?
What new skills will be required? Do the existing staff members have
these skills? If not, can they be trained in due course of time?
The system is operationally feasible as it very easy for the End users to
operate it. It only needs basic information about Windows platform.
3.4) Schedule feasibility
Time evaluation is the most important considerationin the developmentof
project.The time schedule required for the developedof this project is very
important since more developmenttime effectmachine time, cost and
cause delay in the developmentof other systems.
A reliable Hospital ManagementSystem can be developed inthe
considerable amount of time.

generated data. More so, a simple and interactive Graphical User
Interface (GUI) is one of the success indicators of any application
project. This chapter presents the database and GUI design for this
Hospital Management application.
5.1 Database Design
MySQL database management system is the most popular database
system for Java applications because of its speed, reliability, and
flexibility. All the data generated by this application are managed on

6.3 New User
The implementation of registering new user is given below.
Connect.DB() method is used to connect the application with database.
The “fieldname.equals()”(the field name may vary) method makes sure
that none of the entry is left blank. The string “sql2” is used to check
that already existed username in the database is not entered while
registering as a new user. If any text field is left blank then a
corresponding message is shown in dialog box with the help of
JOPtionPane.showMessageDialog() method. If the username entered is
not as same as one in the database then string “sql2” is used to enter the
details entered in the registration form to be stored in the database.

8. CONCLUSION
The project Hospital ManagementSystem (HMS) is for computerizing the
working in a hospital. The software takes care of all the requirements of an average
hospital and is capable to provide easy and effective storage of information related
to patients that come up to the hospital.
It generates test reports; provide prescription details including various tests, diet
advice, and medicines prescribed to patient and doctor. It also provides injection
details and billing facility on the basis of patient’s status whether it is an indoor or
outdoorpatient. The system also provides the facility of backup as per the
requirement.
Future Enhancements
The proposed system is Hospital Management System. We can enhance
