2. SYSTEM STUDY
The system is
studied to the minutes detail and analyzed. The system analyst
plays the role of the interrogator and dwells deep into the working of the present system.
The system is viewed as a whole and the input to the system are identified. The outputs
from the organizations are traced to the various processes. System analysis is concerned
with becoming aware of the problem, identifying the relevant and decisional variables,
analyzing and synthesizing the various factors and determining an optimal or at least a
satisfactory solution or program of action.

analyzing and synthesizing the various factors and determining an optimal or at least a
satisfactory solution or program of action.
2.1. EXISTING SYSTEM
System
analysis is a detailed study of the various operations performed by a system
and their relationships within and outside of the system.
Here the key question is-what all the
problems exist in the present system? What must be done to solve the problem?
Analysis
begins when a user or manager begins a study of the program using existing
system .the success of the system depends largely on how clearly the problem is
defined, thoroughly investigated and properly carried out through the choice of
solution. A good analysis model should provide not only the mechanisms of
problem understanding but also the frame work of the solution. Then the
proposed system should be analyzed
thoroughly in accordance with the
needs.
Problems with existing
system
- · The existing system only provides text-based interface, which is not as user-friendly as Graphical user Interface.
- · Since the system is implemented in Manual, so the response is very slow.
- · Off-line reports cannot be generated due to batch mode execution.
- · Lack of security of data.
- · More man power.
- · Time consuming.
- · Consumes large volume of pare work.
- · Needs manual calculations.
- · Damage of machines due to lack of attention.
2.2. PROPOSED SYSTEM
The drawback of the system is that it is
very difficult to retrieve case files. It is difficult to handle the whole
system manually and it is less accurate and to keep the data in case files for
future reference because it may get destroyed. Moreover it is very difficult to
retrieve data. The manual system is so time-consuming.
The proposed system is very easy to operate speed and
accuracy are the main advantages of proposed system. There is no redundancy of
data. The proposed system will not handle all the data and work done the
existing systems. The proposed system eliminates the drawbacks of the existing
system to a great extend and it provides tight security to data.
FEATURES
·
Ensure data accuracy
·
Reduce the damages of the machines.
·
Minimize manual data entry.
·
Minimum time needed for the various
processing.
·
Greater efficiency.
·
Better service.
·
User friendliness and interactive.
·
Minimum time required.
·
Security of data
3. SYSTEM REQUIREMENT
HOSPITAL MANAGEMENT
SYSTEM system-requirement Hardware specifications Hardware is a set of physical
components, which performs the functions of applying appropriate, predefined
instructions. In other words, one can say that electronic and mechanical parts
of computer constitute hardware. This package is designed on a powerful
programming language using C++. The backend is MSWord, which is used to
maintain database. It can run on almost all the popular microcomputers. The
following are the minimum hardware specifications to run this package:
-Personal Computer: -It minimum contains P-III Processor with 128 MB RAM.
Software Requirements: Hospital Management
System software is a set of procedures of coded information or a program which
when fed into the computer hardware, enables the computer to perform the
various tasks.
Functional and Non functional software
requirements
Functional requirements are the main
things that the user expects from the software. In the banking application that
application should be able to add normal patient,add critical patient, list of
patient, remove patient etc. Functional requirements are detailed and are
specified in the system design.
Non-functional requirements are not
straight forward requirement of the system rather it is related to the usability.

C++
programming language:
Program
is a sequence of instructions given to a computer to be executed to perform a
desired task. Every program is written in some programming language and C++ is
such a language developed at AT&T Bell Laboratories by Bajarne Strostrup in
the 1980’s. Based upon the languages C
and Simula, it has become the most popular language for object oriented
programming, which is a programming style.
Object
oriented languages incorporate all the features of object based programming
languages along with inheritance and polymorphism. Making classes and objects
is the fundamental building blocks of OOPs. The languages such as C++, Java,
Smalltalk, Eiffel etc. Support Object Oriented Programming.
The following are the
important features of Object Oriented languages:
Ø Improvement
over the structured programming paradigm.
Ø Emphasis
on data rather than algorithm.
Ø Data
abstraction is introduced in addition to procedural abstraction.
Ø Decomposition
is on data rather than procedure.
Ø Relationships
can be created between similar, yet distinct data types.
Ø The
advantage of OOP lies in its suitability in various applications. Interacting
easily with computational environment using familiar descriptions.
MS
Word:
With MS Word we can
create documents of any kind with ease. It helps in producing error free
documents. A document can be seen on the computer screen and revised until it
is perfect. There after i may be printed on the printer. The documents can also
be saved on a disk. MS Word helps us to create letters, proposals, web pages,
business plans, resumes, novels, and even graphic based multi-column
publications.
4.SYSTEM ANALYSIS
System analysis
is the application of the system approach
to the study and solution of problem using computer
based system . System thinking is
integral to system work. Organisation is
the complex is complex system that consist of interrelated and interlocking
subsystem .Changes are one part of the system having both anticipated and
unanticipated consequences’ in other part of the system. The approach is way of
thinking about the analysis and design of computer trends application .It
proves a frame work for visualizing the organizational and environmental features
that operate on a system .When a computer is introduced in an organization,
various functions and Dysfunction operates on the user as well as the
organization .
4.1
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 proposal according to its workability.
System
Analysis is a detailed study of the various operations performed by a system
and their relationships within and outside of the system. Here the key question
is what all problems exist in the present system? What must be done to solve
the problem?
Analysis begins when a user or manager begins
a study of the program using existing system. During analysis, data collected
on the various files, decision points
and transactions handled by the present system. Training, experience and common
sense are required for collection of relevant information needed to develop the
system. The success of the system depends largely on how clearly the problem is
defined, thoroughly investigated and properly carried out through the choice of
solution. A good analysis model should provide not only the mechanisms of
problem understanding but also the frame work of the solution. Thus, it should
System planning and initial investigation Information Gathering Applying
analysis tools for structured analysis Feasibility study Cost/ Benefit
analysis. In our existing system, all the transaction of books are done
manually, so taking more time for a transaction like borrowing a book or
returning a book and also for searching of members and books. Another major
disadvantage is that preparing the list of books borrowed and the available
books in the library will take more time, currently a one day process for
verifying all marketing management system.
he
organization, ability to meet needs and effective use of the resources. It
focuses on these major questions:
Ø What
are the user’s demonstrable needs and how does a candidate system meet them?
Ø What
resources are available for given candidate system?
Ø What
are the likely impacts of the candidate system on the organization?
Ø Whether
it is worth to solve the problem?
Ø During
feasibility analysis for this project, following primary areas of interest are
to be considered.
Ø Investigation
and generating ideas about a new system does this.
4.1.1.ECONOMIC
& TECHNICAL FEASIBLITY
TECHNICAL
FEASIBLITY
A study of resource availability that
may affect the ability to achieve an acceptable system. This evaluation
determines whether the technology needed for the proposed system is available
or not.
1) Can the work for the project be done with
current equipment existing software technology & available personal?
2) Can
the system be upgraded if developed?
3) If new technology is needed then what can be
developed?
4) This
is concerned with specifying equipment and software that will successfully satisfy the user requirement.
ECONOMICAL FEASIBLITY
Economic justification is generally the
“Bottom Line” consideration for most systems. Economic justification includes a
broad range of concerns that includes cost benefit analysis. In this we weight
the cost and 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 design phase. The financial and the economic questions
during the preliminary investigation are verified to estimate the following:
1) The cost to conduct a full system
investigation.
2) The
cost of hardware and software for the class of application being considered.
3) The benefits in the form of reduced cost.
4) The proposed system will give the minute information,
as a result the performance is improved which in turn may be expected to
provide increased profits.
5) This
feasibility checks whether the system can be developed with the available
funds. The Hospital Management System does not require enormous amount of money
to be developed. This can be done economically if planned judicially, so it is
economically feasible. The cost of project depends upon the number of manhours
required.
4.1.2.SOCIAL
& BEHAVIOUR FEASIBLITY
SOCIAL
Its part would determine the proposed project
will be satisfactory for the people or not. This assumption would in general
examine the probability that the project would have to be accepted by the group
of people that are directly affected by the proposed system.
BEHAVIOURAL
Behavioural feasibility determines how much
effort will go into educating, managing, training the user staff for the
system. The organizer and the end user will be supported in this system.
5.SYSTEM DESIGN
Software engineering is
carry out of using preferred procedure techniques to progress the quality of a
software development effort. A methodology is defined as a collection of
procedures, techniques, tools, and documentation aids which will help
developers in their efforts (both product and process related activities) to
implement a new system. For successful implementation, a well-organized and
systematic approach is crucial. Therefore, several methodologies were developed
to encourage the systematic approach to planning, analysis, design, testing and
implementation. Methodologies offer various
tools and techniques to
assist in analysis,
design and testing
in terms of
detailed design of software, data flowcharts and database
design
5.1.INPUT DESIGN
Input design is the
process of converting user-oriented input to a computer based format. Input
design is a part of overall system design, which requires very careful
attention .Often the collection of input data is the most expensive part of the
system. The main objectives of the input design are:
1. Produce cost effective method of input
2. Achieve highest possible level of
accuracy
3. Ensure that the input is acceptable to
and understood by the staff.
Input
Data: The goal of designing input data is to make enter easy, logical and free
from errors as possible. The entering data entry operators need to know the
allocated space for each field; field sequence and which must match with that
in the source document. The format in which the data fields are entered should
be given in the input form .Here data entry is online; it makes use of
processor that accepts commands and data from the operator through a key board.
The input required is analyzed by the processor. It is then accepted or
rejected. Input stages include the following processes: Data Recording Data
Transcription Data Conversion Data Verification Data Control Data Transmission
Data Correction. One of the aims of the system analyst must be to select data
capture method and devices, which reduce the number of stages so as to reduce
both the changes of errors and the cost .Input types, can be characterized as.
External Internal Operational Computerized Interactive Input files can exist in
document form before being input to the computer. Input design is rather
complex since it involves procedures for capturing data as well as inputting it
to the computer
5.2.OUTPUT DESIGN
Outputs from computer systems are required primarily
to communicate the results of processing to users. They are also used to
provide a permanent copy of these result for latter consultation .Computer
output is the most important and direct source of information to the users.
Designing computer output should proceed in an organized well throughout the
manner. The right output must be available for the people who find the system
easy to use. The outputs have been defined during the logical design stage. If
not, they should defined at the beginning of the output designing terms of
types of output connect, format, response etc. Various types of outputs are:
• External outputs
• Internal outputs
• Operational outputs
• Interactive outputs
• Turn around outputs
All
screens are informative and interactive in such a way that the user can full
fill his requirements through asking queries.
5.3 INTERFACE DESIGN
Interface Design is the design
of user to interfaces between machines
and software,
such as computers,
home appliances, mobile devices,
and other electronic devices, with the focus on maximizing the user experience.
The goal of Interface Design is to make
the user's interaction as simple and efficient as possible, in terms of
accomplishing user goals (user-centred design).
Good interface design facilitates finishing the
task at hand without drawing unnecessary attention to itself graphic design and
typography
are utilized to support its usability,
influencing how the user performs certain interactions and improving the
aesthetic appeal of the design; design aesthetics may enhance or detract from
the ability of users to use the functions of the interface. The design process
must balance technical functionality and visual elements (e.g., mental model)
to create a system that is not only operational but also usable and adaptable
to changing user needs.
Interface
design is involved in a wide range of projects from computer systems, to cars,
to commercial planes; all of these projects involve much of the same basic
human interactions yet also require some unique skills and knowledge. As a
result, designers tend to specialize in certain types of projects and have
skills centred on their expertise, whether that be software design,
user research, web design, or industrial design.
In
“Bus Reservation System”, the interface support a GUI window, is very user friendly.
The easy by just typing or mouse clicking. The forms are dynamical in nature to
check whether a field is empty or note. The working of each links and all other
graphical buttons and menus and handling of each object in the system in that
particular moment, without going to search on any user manual or help option.
5.4
PROCEDURAL DESIGN
Procedural design occurs after data and
interface design has been established. The intent is to translate the design model in to operational software.
Procedural design establishes the algorithmic detail require to manipulate data
structures, effect communication between software components via their interface and implement the processing
algorithm allocated to each component.
5.5
FILE DESIGN
Data
loss is always a basic concern in designing a file system. Usually in large
computer systems, many preventive and recovery procedures are prepared.
Sometimes they may require the intervention of a trained operator. But in small
computer systems where casual operators are most likely users, nothing can be
expected from them in recovery. Here a file system, which assumes “Assurance of
user data integrity and automatic recovery against any unexpected power
failure” as a design point, which comes from the characteristics of the working
environment of small computer systems, has been designed. The concepts of “System
log”, “Deferred update”, and “Checkpoint” were introduced into this file
system. The methods to realize the design concepts are also presented. File design deals with selecting
the method of storing and retrieving data in a system. In file design, the
system analyst decides the medium of files storage, what files are required,
what data’s are stored in each file, and also the method of organizing records
in a file. The structure of each file is determined. For example an inventory
file will contain the item code, item name, quantity in stock etc.
A file can be defined as a
collection of related data that is stored in a storage medium. A file consists
of a collection of records, where each record represents, data about an entity.
A record is a collection of data related to a specified entity. A field is a
smallest logical unit of data. Each field is identified by a name.
File
functions used in the case study are:

commonly used during problem analysis.they are useful in understanding a system
and are efficient system usedfor partitioning during analysis .

·
The process within the system
·
The data stores (files) supporting the
system’s operation
·
The information flows within the system
·
The systems boundary
·
Interaction with external entities
DFD
PRINCIPLES:
·
General principles in data flow
diagramming are that a system can be decomposed into subsystems, and subsystems
can be decomposed into lower level subsystem , and so on .
·
Each subsystem represents a process or
activity in which data is processed .at the lowest level , processes can no
longer be decomposed
·
Each ‘process’ in a DFD has the characteristics
of a system.
·
Just as a system must have input and
output, so a process must have input and
out put
·
Data enters the system from the
environment; data flows between the processes within the system ;and data is
produced as output from the system.
DATA FLOW DIAGRAM
6.IMPLEMENTATION AND TESTING
Implementation is the
process of converting a new or revised system design into an optional one .It
is key stage in achieving a successful new system, because usually it involves
a lot of up level in the user department
6.1
SYSTEM TESTING
In system testing we have to test the programs
making up the system. The software units in a system are the modules and
routines that are assembled and integrated to perform a specific function.
System testing focuses on the module independent ant of one another, in order
locate errors. The common view of testing held by users is that it is performed
to prove that there are no errors in a program .However ,as indicated earlier
,this is virtually impossible , since analyst cannot prove that software is
free and clear of errors .Analyst’s know that an effective testing program does
not guarantee system reliability.
Therefore reliability must be designed into the system
7. CONCLUTION
The project Hospital Management
System 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 provides details of patients like, normal , ill , out for
operation , dead. The system also provides the facility backup as per the
requirements
