INTRODUCTION & OBJECTIVE
The objective of
this application is to develop a system that automates and organizes the
ambulance service sector. The purpose is to maintain a well-defined interface
to the offered services and maintain a centralized database of entire
information.
EXISTING SYSTEM
The present system is not efficient and effective as the entire data is
maintained across various files and systems. It is difficult to access the data
and perform the necessary operations. The system cannot respond properly to
emergency situations.
PROPOSED SYSTEM
The proposed system organizes the data
effectively. It provides mechanisms to communicate information efficiently and
accurately. It provides information regarding ambulance services offered by
different hospitals. It is easy to generate reports. Users can access the
information quickly.
STUDY OF THE SYSTEM
To provide flexibility to the users, the interfaces
have been developed that are accessible through a browser. The GUI’S at the top
level have been categorized as
1.
Administrative
user interface
2.
The
operational or generic user interface
The ‘administrative user
interface’ concentrates on the consistent information that is practically, part
of the organizational activities and which needs proper authentication for the
data collection. These interfaces help the administrators with all the
transactional states like Data insertion, Data deletion and Date updation along
with the extensive data search capabilities.
The ‘operational or generic user interface’ helps
the end users of the system in transactions through the existing data and
required services. The operational user interface also helps the ordinary users
in managing their own information in a customized manner as per the included
flexibilities
INPUT & OUTPOUT REPRESENTETION
Input design is a part of overall system
design. The main objective during the
input design is as given below:
·
To
produce a cost-effective method of input.
·
To
achieve the highest possible level of accuracy.
·
To
ensure that the input is acceptable and understood by the user.
INPUT STAGES:
The main input stages can be
listed as below:
·
Data
recording
·
Data
transcription
·
Data
conversion
·
Data
verification
·
Data
control
·
Data
transmission
·
Data
validation
·
Data
correction
INPUT TYPES:
It is necessary to determine the various types of
inputs. Inputs can be categorized as
follows:
·
External
inputs, which are prime inputs for the system.
·
Internal
inputs, which are user communications with the system.
·
Operational,
which are computer department’s communications to the system?
·
Interactive,
which are inputs entered during a dialogue.
INPUT MEDIA:
At this stage choice has to be
made about the input media. To conclude
about the input media consideration has to be given to;
·
Type
of input
·
Flexibility
of format
·
Speed
·
Accuracy
·
Verification
methods
·
Rejection
rates
·
Ease
of correction
·
Storage
and handling requirements
·
Security
·
Easy
to use
·
Portability
Keeping in view the above description of the input
types and input media, it can be said that most of the inputs are of the form
of internal and interactive. As
Input
data is to be the directly keyed in by the user, the keyboard can be considered
to be the most suitable input device.
OUTPUT DESIGN:
In general are:
·
External
Outputs whose destination is outside the organization.
·
Internal
Outputs whose destination is with in organization and they are the User’s main
interface with the computer. 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 the results for later consultation. The various
types of outputs
·
Operational
outputs whose use is purely with in the computer department.
·
Interface
outputs, which involve the user in communicating directly with the system.
OUTPUT DEFINITION
The outputs should be defined in terms of the following points:
§ Type of the output
§ Content of the output
§ Format of the output
§ Location of the output
§ Frequency of the output
§ Volume of the output
§ Sequence of the output
It is not always desirable to print or display data
as it is held on a computer. It should be decided as which form of the output
is the most suitable.
For Example
·
Will
decimal points need to be inserted
·
Should
leading zeros be suppressed.
OUTPUT
MEDIA:
In the next stage it is to be decided that which
medium is the most appropriate for the output. The main considerations when
deciding about the output media are:
·
The
suitability for the device to the particular application.
·
The
need for a hard copy.
·
The
response time required.
·
The
location of the users
·
The
software and hardware available.
Keeping in view the above
description the project is to have outputs mainly coming under the category of
internal outputs. The main outputs desired according to the requirement
specification are:
The outputs were needed to be generated as a hard
copy and as well as queries to be viewed on the screen. Keeping in view these outputs, the format for
the output is taken from the outputs, which are currently being obtained after
manual processing. The standard printer
is to be used as output media for hard copies.
This
application consists following modules.
1.
Administrator module
2.
Employee module
3. Report
module
1. Administrator
module:
Administrator manages the entire
application. Administrator can add, delete, edit and view the employee details.
Administrator also manages the doctor’s details along with other attendants.
Administrator keeps track of ambulances available and their current status.
2. Report module:
This module allows one to generate
reports based on different criteria such as ambulance details, employee
details, patient details, services offered and so on.
3. Employee (Hospital In-charge) module:
This module allows employees to
register and manage patient details. When a request is made, an employee
immediately dispatches an ambulance with available doctor and other attendants.
Employee keeps track of patient status and in case of emergency consults a
hospital for admitting the patient.
PERFORMANCE REQUIREMENTS
Performance is measured in terms of the output
provided by the application. Requirement specification plays an important part
in the analysis of a system. Only when the requirement specifications are
properly given, it is possible to design a system, which will fit into required
environment. It rests largely with the users of the existing system to give the
requirement specifications because they are the people who finally use the
system. This is because the requirements
have to be known during the initial stages so that the system can be designed
according to those requirements. It is
very difficult to change the system once it has been designed and on the other
hand designing a system, which does not cater to the requirements of the user,
is of no use.
The requirement specification
for any system can be broadly stated as given below:
·
The
system should be able to interface with the existing system
·
The
system should be accurate
·
The
system should be better than the existing system
The existing system is completely dependent on the
user to perform all the duties.
