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
- Administrative user interface
- 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.

APPROACH
OF THE PROJECT:
This Document plays a vital role in
the development life cycle (SDLC) as it describes the complete requirements of
the system. It is meant for use by the developers and will be the basic during
testing phase. Any changes made to the requirements in the future will have to
go through formal change approval process.
OOAD MODEL was being chosen because
all requirements were known beforehand and the objective of our software
development is the computerization/automation of an already existing manual
working system.
Fig 2.2: SDLC Model
The developer is responsible for:
·
Developing
the system, which meets the SRS and solving all the requirements of the system?
·
Demonstrating
the system and installing the system at client's location after the acceptance
testing is successful.
·
Submitting
the required user manual describing the system interfaces to work on it and
also the documents of the system.
·
Conducting
any user training that might be needed for using the system.
·
Maintaining
the system for a period of one year after installation.
INPUT DESIGN:
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:
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 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.
- 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.

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.
FEASIBILITY REPORT:
Preliminary investigation examines
project feasibility, the likelihood the system will be useful to the
organization. The main objective of the feasibility study is to test the
Technical, Operational and Economical feasibility for adding new modules and
debugging old running system. All systems are feasible if they are given unlimited
resources and infinite time. There are aspects in the feasibility study portion
of the preliminary investigation:
- Technical
Feasibility
- Operation
Feasibility
- Economical
Feasibility
Technical Feasibility
The technical issue usually raised
during the feasibility stage of the investigation includes the following:
- Does
the necessary technology exist to do what is suggested?
- Do
the proposed equipments have the technical capacity to hold the data
required to use the new system?
- Will
the proposed system provide adequate response to inquiries, regardless of
the number or location of users?
- Can
the system be upgraded if developed?
- Are
there technical guarantees of accuracy, reliability, ease of access and
data security?
Operational Feasibility
Proposed projects are beneficial
only if they can be turned out into information systems, that will meet the
organization’s operating requirements. Operational feasibility aspects of the
project are to be taken as an important part of the project implementation.
Some of the important issues raised are to test the operational feasibility of
a project includes the following: -
·
Is
there sufficient support for the management from the users?
·
Will
the system be used and work properly if it is being developed and implemented?
·
Will
there be any resistance from the user that will undermine the possible
application benefits?
This system is targeted to be in
accordance with the above-mentioned issues. Beforehand, the management issues
and user requirements have been taken into consideration. So there is no
question of resistance from the users that can undermine the possible
application benefits.
The well-planned design would ensure
the optimal utilization of the computer resources and would help in the
improvement of performance status.
Economic Feasibility
A system can be developed
technically and that will be used if installed must still be a good investment
for the organization. In the economical feasibility, the development cost in
creating the system is evaluated against the ultimate benefit derived from the
new systems. Financial benefits must equal or exceed the costs. The system is
economically feasible. It does not require any additional hardware or software.
