SYSTEM STUDY AND ANALISYS
SYSTEM ANALYSIS
System analysis is a process of gathering and interpreting facts, diagnosing problems
and the information to recommend improvements on the system. It is a problem solving
activity that requires intensive communication between the system users and system
developers. System analysis or study is an important phase of any system development
process. The system is studied to the minutest 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.
A detailed study of the process must be made by various techniques like interviews,
questionnaires etc. The data collected by these sources must be scrutinized to arrive to a
conclusion. The conclusion is an understanding of how the system functions. This system
is called the existing system. Now the existing system is subjected to close study and
problem areas are identified. The designer now functions as a problem solver and tries to
sort out the difficulties that the enterprise faces. The solutions are given as proposals. The
proposal is then weighed with the existing system analytically and the best one is
selected. The proposal is presented to the user for an endorsement by the user. The
proposal is reviewed on user request and suitable changes are made. This is loop that
ends as soon as the user is satisfied with proposal.
Preliminary study is the process of gathering and interpreting facts, using the
information for further studies on the system. Preliminary study is problem solving
activity that requires intensive communication between the system users and system
developers. It does various feasibility studies. In these studies a rough figure of the
system activities can be obtained, from which the decision about the strategies to be
followed for effective system study and analysis can be taken.
EXISTING SYSTEM
In the existing system the transactions are done only manually but in proposed
system we have to computerize all the banking transaction using the software financial
management system.

2. 1.1 PROBLEMS WITH EXISTING SYSTEM
 Lack of security of data.
 More man power.
 Time consuming.
 Consumes large volume of pare work.
 Needs manual calculations.
 No direct role for the higher officials.
 Damage of machines due to lack of attention.
To avoid all these limitations and make the working more accurately the system needs to
be computerized.
PROPOSED SYSTEM
The aim of proposed system is to develop a system of improved facilities. The
proposed system can overcome all the limitations of the existing system. The system
provides proper security and reduces the manual work.
2. 2. 1 ADVANTAGES OF THE PROPOSED SYSTEM
The system is very simple in design and to implement. The system requires very low
system resources and the system will work in almost all configurations. It has got
following features
 Security of data.
 Ensure data accuracy’s.
 Proper control of the higher officials.
 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.
2.3. FEASIBILITY STUDY
Feasibility study is made to see if the project on completion will serve the purpose of
the organization for the amount of work, effort and the time that spend on it. Feasibility
study lets the developer foresee the future of the project and the usefulness. A feasibility
study of a system proposal is according to its workability, which is the impact on the
organization, ability to meet their user needs and effective use of resources. Thus when a
new application is proposed it normally goes through a feasibility study before it is
approved for development.
4
The document provide the feasibility of the project that is being designed and lists
various areas that were considered very carefully during the feasibility study of this
project such as Technical, Economic and Operational feasibilities. The following are its
features:
2.3.1. TECHNICAL FEASIBILITY
The system must be evaluated from the technical point of view first. The assessment
of this feasibility must be based on an outline design of the system requirement in the
terms of input, output, programs and procedures. Having identified an outline system, the
investigation must go on to suggest the type of equipment, required method developing
the system, of running the system once it has been designed.
Technical issues raised during the investigation are:
Does the existing technology sufficient for the suggested one?
Can the system expand if developed?
The project should be developed such that the necessary functions and performance
are achieved within the constraints. The project is developed within latest technology.
Through the technology may become obsolete after some period of time, due to the fact
that never version of same software supports older versions, the system may still be used.
So there are minimal constraints involved with this project. The system has been
developed using Java the project is technically feasible for development.
2.3.2. ECONOMIC FEASIBILITY
The developing system must be justified by cost and benefit. Criteria to ensure that
effort is concentrated on project, which will give best, return at the earliest. One of the
factors, which affect the development of a new system, is the cost it would require.
The following are some of the important financial questions asked during preliminary
investigation:
 The costs conduct a full system investigation.
 The cost of the hardware and software.
 The benefits in the form of reduced costs or fewer costly errors.
Since the system is developed as part of project work, there is no manual cost to spend
for the proposed system. Also all the resources are already available, it give an indication
of the system is economically possible for development.
2.3.3. BEHAVIORAL FEASIBILITY
5
This includes the following questions:
 Is there sufficient support for the users?
 Will the proposed system cause harm?
The project would be beneficial because it satisfies the objectives when developed and
installed. All behavioral aspects are considered carefully and conclude that the project is
behaviorally feasible.
SYSTEM DESIGN
3.1 INTRODUCTION
Design is the first step into the development phase for any engineered product or
system. Design is a creative process. A good design is the key to effective system. The
term “design” is defined as “the process of applying various techniques and principles for
the purpose of defining a process or a system in sufficient detail to permit its physical
realization”. It may be defined as a process of applying various techniques and principles
for the purpose of defining a device, a process or a system in sufficient detail to permit its
physical realization. Software design sits at the technical kernel of the software
engineering process and is applied regardless of the development paradigm that is used.
The system design develops the architectural detail required to build a system or product.
As in the case of any systematic approach, this software too has undergone the best
possible design phase fine tuning all efficiency, performance and accuracy levels. The
design phase is a transition from a user oriented document to a document to the
programmers or database personnel. System design goes through two phases of
development: Logical and Physical Design.
LOGICAL DESIGN:
The logical flow of a system and define the boundaries of a system. It includes the
following steps:
 Reviews the current physical system – its data flows, file content, volumes ,
frequencies etc.
 Prepares output specifications – that is, determines the format, content and
frequency of reports.
 Prepares input specifications – format, content and most of the input functions.
 Prepares edit, security and control specifications.
 Specifies the implementation plan.
 Prepares a logical design walk through of the information flow, output, input,
controls and implementation plan.
 Reviews benefits, costs, target dates and system constraints.
PHYSICAL DESIGN:
Physical system produces the working systems by define the design specifications that
tell the programmers exactly what the candidate system must do. It includes the following
steps.
 Design the physical system.
6
 Specify input and output media.
 Design the database and specify backup procedures.
 Design physical information flow through the system and a physical design Walk
through.
 Plan system implementation.
 Prepare a conversion schedule and target date.
 Determine training procedures, courses and timetable.
 Devise a test and implementation plan and specify any new hardware/software.
 Update benefits , costs , conversion date and system constraints
Design/Specification activities:
 Concept formulation.
 Problem understanding.
 High level requirements proposals.
 Feasibility study.
 Requirements engineering.
 Architectural design.
MODULE DESIGN
Admin
The Administrator logs in using the admin login. In this administrator has the
full authority over the software. In this System ,the administrator has the power to add or
update or delete all the details.
User
The User logs in using the User login. In this module the user can successfully
enter into the software if it is a authenticated user.
INPUT DESIGN
The design of input focuses on controlling the amount of input required, controlling
the errors, avoiding delay, avoiding extra steps and keeping the process simple. The input
is designed in such a way so that it provides security and ease of use with retaining the
privacy. Input Design considered the following things:
o What data should be given as input?
o How the data should be arranged or coded?
o The dialog to guide the operating personnel in providing input.
o Methods for preparing input validations and steps to follow when error
occur.
7
OBJECTIVES
Input Design is the process of converting a user-oriented description of the input into a
computer-based system. This design is important to avoid errors in the data input process
and show the correct direction to the management for getting correct information from
the computerized system.
It is achieved by creating user-friendly screens for the data entry to handle large volume
of data. The goal of designing input is to make data entry easier and to be free from
errors. The data entry screen is designed in such a way that all the data manipulates can
be performed. It also provides record viewing facilities.
When the data is entered it will check for its validity. Data can be entered with the help of
screens. Appropriate messages are provided as when needed so that the user will not be in
a maize of instant. Thus the objective of input design is to create an input layout that is
easy to follow
OUTPUT DESIGN
A quality output is one, which meets the requirements of the end user and presents the
information clearly. In output design it is determined how the information is to be
displaced for immediate need and also the hard copy output. It is the most important and
direct source information to the user. Efficient and intelligent output design improves the
system’s relationship to help user decision-making.
Designing computer output should proceed in an organized, well thought out manner;
the right output must be developed while ensuring that each output element is designed so
that people will find the system can use easily and effectively. When analysis design
computer output, they should :
 Identify the specific output that is needed to meet the requirements.
 Select methods for presenting information.
 Create document, report, or other formats that contain information produced by
the system.
3.3 DATABASE DESIGN
A database is an organized mechanism that has the capability of storing information
through which a user can retrieve stored information in an effective and efficient manner.
The data is the purpose of any database and must be protected.
The database design is a two level process. In the first step, user requirements are
gathered together and a database is designed which will meet these requirements as
clearly as possible. This step is called Information Level Design and it is taken
independent of any individual DBMS.
In the second step, this Information level design is transferred into a design for the
specific DBMS that will be used to implement the system in question. This step is called
8
Physical Level Design, concerned with the characteristics of the specific DBMS that will
be used. A database design runs parallel with the system design. The organization of the
data in the database is aimed to achieve the following two major objectives.
 Data Integrity
 Data independence
Normalization is the process of decomposing the attributes in an application, which
results in a set of tables with very simple structure. The purpose of normalization is to
make tables as simple as possible. Normalization is carried out in this system for the
following reasons.
 To structure the data so that there is no repetition of data , this helps in saving.
 To permit simple retrieval of data in response to query and report request.
 To simplify the maintenance of the data through updates, insertions, deletions.
 To reduce the need to restructure or reorganize data which new application
requirements arise.
RELATIONAL DATABASE MANAGEMENT SYSTEM (RDBMS):
A relational model represents the database as a collection of relations. Each relation
resembles a table of values or file of records. In formal relational model terminology, a
row is called a tuple, a column header is called an attribute and the table is called a
relation. A relational database consists of a collection of tables, each of which is assigned
a unique name. A row in a tale represents a set of related values.
RELATIONS, DOMAINS & ATTRIBUTES:
A table is a relation. The rows in a table are called tuples. A tuple is an ordered set of
n elements. Columns are referred to as attributes. Relationships have been set between
every table in the database. This ensures both Referential and Entity Relationship
Integrity. A domain D is a set of atomic values. A common method of specifying a
domain is to specify a data type from which the data values forming the domain are
drawn. It is also useful to specify a name for the domain to help in interpreting its values.
Every value in a relation is atomic, that is not decomposable.
RELATIONSHIPS:
Table relationships are established using Key. The two main keys of prime importance
are Primary Key & Foreign Key. Entity Integrity and Referential Integrity Relationships
can be established with these keys.Entity Integrity enforces that no Primary Key can have
null values.Referential Integrity enforces that no Primary Key can have null values.
Referential Integrity for each distinct Foreign Key value, there must exist a matching
Primary Key value in the same domain. Other key are Super Key and Candidate Keys.
Relationships have been set between every table in the database. This ensures both
Referential and Entity Relationship Integrity.

NORMALIZATION:
As the name implies, it denoted putting things in the normal form. The application
developer via normalization tries to achieve a sensible organization of data into proper
tables and columns and where names can be easily correlated to the data by the user.
Normalization eliminates repeating groups at data and thereby avoids data redundancy
which proves to be a great burden on the computer resources. These includes:
 Normalize the data.
 Choose proper names for the tables and columns.
 Choose the proper name for the data.
First Normal Form:
The First Normal Form states that the domain of an attribute must include only atomic
values and that the value of any attribute in a tuple must be a single value from the
domain of that attribute. In other words 1NF disallows “relations within relations” or
“relations as attribute values within tuples”. The only attribute values permitted by 1NF
are single atomic or indivisible values.
The first step is to put the data into First Normal Form. This can be donor by moving
data into separate tables where the data is of similar type in each table. Each table is
given a Primary Key or Foreign Key as per requirement of the project. In this we form
new relations for each nonatomic attribute or nested relation. This eliminated repeating
groups of data.
A relation is said to be in first normal form if only if it satisfies the constraints that
contain the primary key only.
Second Normal Form:
According to Second Normal Form, For relations where primary key contains multiple
attributes, no nonkey attribute should be functionally dependent on a part of the primary
key.
In this we decompose and setup a new relation for each partial key with its dependent
attributes. Make sure to keep a relation with the original primary key and any attributes
that are fully functionally dependent on it. This step helps in taking out data that is only
dependant on apart of the key.
A relation is said to be in second normal form if and only if it satisfies all the first
normal form conditions for the primary key and every non-primary key attributes of the
relation is fully dependent on its primary key alone.
Third Normal Form:
According to Third Normal Form, Relation should not have a nonkey attribute
functionally determined by another nonkey attribute or by a set of nonkey attributes. That
is, there should be no transitive dependency on the primary key.
10
In this we decompose and set up relation that includes the nonkey attributes that
functionally determines other nonkey attributes. This step is taken to get rid of anything
that does not depend entirely on the Primary Key.
A relation is said to be in third normal form if only if it is in second normal form and
more over the non key attributes of the relation should not be depend on other non key
attribute.
4.2 SOFTWARE ENVIRONMENT
The Control Properties
Before writing an event procedure for the control to response to a user's input, you have
to set certain properties for the control to determine its appearance and how it will work
with the event procedure. You can set the properties of the controls in the properties
window or at runtime.
5.2 SYSTEM IMPLEMENTATION AND TESTING
Implementation is the stage of the project where the theoretical design is turned into a
working system. It can be considered to be the most crucial stage in achieving a
successful new system gaining the users confidence that the new system will work and
will be effective and accurate. It is primarily concerned with user training and
documentation. Conversion usually takes place about the same time the user is being
trained or later. Implementation simply means convening a new system design into
operation, which is the process of converting a new revised system design into an
operational one.
5.2.1. SYSTEM TESTING
Software Testing is the process of executing software in a controlled manner, in order
to answer the question - Does the software behave as specified?. Software testing is often
used in association with the terms verification and validation. Validation is the checking
or testing of items, includes software, for conformance and consistency with an
associated specification. Software testing is just one kind of verification, which also uses
techniques such as reviews, analysis, inspections, and walkthroughs. Validation is the
process of checking that what has been specified is what the user actually wanted.
11
Validation : Are we doing the right job?
Verification : Are we doing the job right?
Software testing should not be confused with debugging. Debugging is the process of
analyzing and localizing bugs when software does not behave as expected. Although the
identification of some bugs will be obvious from playing with the software, a methodical
approach to software testing is a much more thorough means for identifying bugs.
Debugging is therefore an activity which supports testing, but cannot replace testing.
Other activities which are often associated with software testing are static analysis and
dynamic analysis. Static analysis investigates the source code of software, looking for
problems and gathering metrics without actually executing the code. Dynamic analysis
looks at the behavior of software while it is executing, to provide information such as
execution traces, timing profiles, and test coverage information.
Testing is a set of activity that can be planned in advanced and conducted
systematically. Testing begins at the module level and work towards the integration of
entire computers based system. Nothing is complete without testing, as it vital success of
the system testing objectives, there are several rules that can serve as testing objectives.
They are
Testing is a process of executing a program with the intend of finding an error.A good
test case is one that has high possibility of finding an undiscovered error.A successful test
is one that uncovers an undiscovered error.
If a testing is conducted successfully according to the objectives as stated above, it
would uncovered errors in the software also testing demonstrate that the software
function appear to be working according to the specification, that performance
requirement appear to have been met.
There are three ways to test program.
 For correctness
 For implementation efficiency
 For computational complexity
Test for correctness are supposed to verify that a program does exactly what it was
designed to do. This is much more difficult than it may at first appear, especially for large
programs.
TEST PLAN
A test plan implies a series of desired course of action to be followed in accomplishing
various testing methods. The Test Plan acts as a blue print for the action that is to be
followed. The software engineers create a computer program, its documentation and
related data structures. The software developers is always responsible for testing the
individual units of the programs, ensuring that each performs the function for which it
was designed. There is an independent test group (ITG) which is to remove the inherent
12
problems associated with letting the builder to test the thing that has been built. The
specific objectives of testing should be stated in measurable terms. So that the mean time
to failure, the cost to find and fix the defects, remaining defect density or frequency of
occurrence and test work-hours per regression test all should be stated within the test
plan.
The levels of testing include:
 Unit testing
 Integration Testing
 Data validation Testing
 Output Testing
UNIT TESTING
Unit testing focuses verification effort on the smallest unit of software design – the
software component or module. Using the component level design description as a guide,
important control paths are tested to uncover errors within the boundary of the module.
The relative complexity of tests and uncovered scope established for unit testing. The unit
testing is white-box oriented, and step can be conducted in parallel for multiple
components. The modular interface is tested to ensure that information properly flows
into and out of the program unit under test. The local data structure is examined to ensure
that data stored temporarily maintains its integrity during all steps in an algorithm’s
execution. Boundary conditions are tested to ensure that all statements in a module have
been executed at least once. Finally, all error handling paths are tested.
Tests of data flow across a module interface are required before any other test is
initiated. If data do not enter and exit properly, all other tests are moot. Selective testing
of execution paths is an essential task during the unit test. Good design dictates that error
conditions be anticipated and error handling paths set up to reroute or cleanly terminate
processing when an error does occur. Boundary testing is the last task of unit testing step.
Software often fails at its boundaries.
Unit testing was done in Sell-Soft System by treating each module as separate entity
and testing each one of them with a wide spectrum of test inputs. Some flaws in the
internal logic of the modules were found and were rectified.
INTEGRATION TESTING
Integration testing is systematic technique for constructing the program structure
while at the same time conducting tests to uncover errors associated with interfacing. The
objective is to take unit tested components and build a program structure that has been
dictated by design. The entire program is tested as whole. Correction is difficult because
isolation of causes is complicated by vast expanse of entire program. Once these errors
are corrected, new ones appear and the process continues in a seemingly endless loop.
13
After unit testing in Sell-Soft System all the modules were integrated to test for any
inconsistencies in the interfaces. Moreover differences in program structures were
removed and a unique program structure was evolved.
VALIDATION TESTING OR SYSTEM TESTING
This is the final step in testing. In this the entire system was tested as a whole with all
forms, code, modules and class modules. This form of testing is popularly known as
Black Box testing or System testing.
Black Box testing method focuses on the functional requirements of the software.
That is, Black Box testing enables the software engineer to derive sets of input conditions
that will fully exercise all functional requirements for a program.
Black Box testing attempts to find errors in the following categories; incorrect or
missing functions, interface errors, errors in data structures or external data access,
performance errors and initialization errors and termination errors.
OUTPUT TESTING OR USER ACCEPTANCE TESTING
The system considered is tested for user acceptance; here it should satisfy the firm’s
need. The software should keep in touch with perspective system; user at the time of
developing and making changes whenever required. This done with respect to the
following points
 Input Screen Designs,
 Output Screen Designs,
 Online message to guide the user and the like.
The above testing is done taking various kinds of test data. Preparation of test data plays
a vital role in the system testing. After preparing the test data, the system under study is
tested using that test data. While testing the system by which test data errors are again
uncovered and corrected by using above testing steps and corrections are also noted for
future use.
5.3. TRAINING
Once the system is successfully developed the next important step is to ensure that the
administrators are well trained to handle the system. This is because the success of a
system invariably depends on how they are operated and used. The implementation
depends upon the right people being at the right place at the right time. Education
involves creating the right atmosphere and motivating the user. The administrators are
familiarized with the run procedures of the system, working through the sequence of
activities on an ongoing basis.
Implementation is the state in the project where the theoretical design is turned into a
working system. By this, the users get the confidence that the system will work
effectively. The system can be implemented only after through testing.
14
The systems personnel check the feasibility of the system. The actual data were
inputted to the system and the working of the system was closely monitored. The master
option was selected from the main menu and the actual data were input through the
corresponding input screens. The data movement was studied and found to be correct
queries option was then selected and this contains various reports. Utilities provide
various data needed for inventory was input and the module was test run. Satisfactory
results were obtained. Reports related to these processes were also successfully
generated. Various input screen formats are listed in the appendix.
Implementation walkthroughs ensure that the completed system actually solves the
original problem. This walkthrough occurs just before the system goes into use, and it
should include careful review of all manuals, training materials and system
documentation. Again, users, the analyst and the members of the computer services staff
may attend this meeting.
CONCLUSION

keep the information of bank employee, transactions, loan solution, ATM information
and account information. The exciting part of this project is; it displays the employee
details, payment details, loan details and transaction details.
