banking system documentation

INTRODUCTION1.1 General Overview of the Problem:

A bank is a commercial or state institution that provides financial services, including issuing money in form of coins, banknotes or debit cards, receiving deposits of money, lending money and processing transactions. A commercial bank accepts deposits from customers and in turn makes loans based on those deposits. Some banks (called Banks of issue) issue banknotes as legal tender. Many banks offer ancillary financial services to make additional profit; for example: selling insurance products, investment products or stock broking.

Currently in most jurisdictions commercial banks are regulated and require permission to operate. Operational authority is granted by bank regulatory authorities and provides right to conduct the most fundamental banking services such as accepting deposits and making loans. A commercial bank is usually defined as an institution that provides selected banking services without meeting the legal definition of bank.

Banks have a long history, and have influenced economy and politics for centuries. In history, the primary purpose of a bank was to provide liquidity to trading companies. Banks advanced funds to allow business to purchase inventory, and collected those funds back with interest when the goods are sold. For centuries, the banking industry only dealt with business not customers. Commercial lending today is a very intense activity, with banks carefully analyzing the financial condition of its business clients to determine the level of risk in each loan transaction. Banking services have expanded to include services directed at individuals and risks in these much smaller transactions are pooled.

1.2 Problem Definition:

Although the basic type of services offered by a bank depends upon the type of bank and the country, services provided usually include:

Taking deposits from their customers and issuing current or checking accounts and savings accounts to individuals and business.

Extending loans to individuals and business Cashing cheque Facilitating money transactions such as wire transfer and cashier’s

cheque Consumer & commercial financial advisory services Financial transactions can be performed through many different

channels:o A branch, banking centre or financial center is a retail location

where a bank or financial institution offers a wide array of face to face services to customers.

o ATM is computerized telecommunications device that provides a financial institution’s customers a method of financial transactions in a public space without the need for a human clerk or bank teller

o Online banking is a term used for performing transactions , payments etc, over internet through a bank, credit union or building society’s secure websites.

We are mainly concerned with developing a banking system where a Customer can submit his/her deposit amount to bank if he/she has an account or can create a new account in this bank. Customer can also view the status of his/her bank account, can view account balance, can modify and delete it.

One can easily maintain the above things if he/she has an account by login through a username and password given to him.

1.3 Analysis of the Problem:

The project that we have undertaken aims to develop a banking system that is clean, user-friendly and multi-functional. Development of this application includes a number of fields such that user feels comfortable and the system appears as dynamic to him. The project “Banking System” includes the following functionalities:

Transactions can be done with minimum user events. All transactional details and accounts are stored in

files on stable storage. Customers can view their own account details and can

use them as necessary Customer can inquire an account and can inquire

about interest All customer’s data are stored in files on a stable

storage Account holders have to pass through a login system

to enter their accounts This system possess password-protected

administrative access; thus preventing the whole management system from unauthorized access

Customer can get help in any time he/she wants

3

1.4The Proposed Solution Strategy:

The application will be extremely beneficial for the Customers intending to use and operate their bank account and will get various benefits in the field of management of accounts on a clean and user-friendly platform.

Complex Banking operations and Transaction operations are efficiently handled by the application

It is cost effective It has ease of use along with complete reference It is highly secured and less time consuming; hence

time wastage can be avoided Up to date records of the customers are maintained by

the authority.

PROJECT PLAN3.1 Life Cycle Model:

Here in the work, we use EVOLUTIONARY MODEL. This is also referred to as successive version model of incremental model.

The project is first broken into several modules, such as developing new accounts (A), developing account modification process (B), and linking between these different features (C) which can be incrementally constructed. The skeleton is refined into increasing levels of capability by adding new functionalities in succession.

We have chosen Evolutionary Model because: 1st implement the main feature as account, then according to requirement step wise implementing is done.

4.2 Data Flow Diagram:

A Data Flow Diagram (DFD) is a graphical representation of the “flow” of data through an information system. A data flow diagram can also be used for the visualization of the data processing (structured design).

Elements of a DFD:

There are four key elements in a Data Flow Diagram; Processes, Data Flows, Data Stores & External entities and each element is drawn differently.

Process entity:

The Process entity identifies a process taking place; it must have at least one input and output. A process with no input is known as a “miracle process” and one with no output is a “black hole process”. Each process has the following:

A Number A Name A Description At least one input At least one output

13

Data flow entity:

The Data Flow Entity identifies the flow of data between processes, data stores & external entities. A data flow cannot connect an external entity to the data source; at least one connection must be with a process. There are also physical flows, i.e., those that use a physical medium. Each data flow has the following:

A Name (Noun) A description One or more connections to a process

Data Store entity:

The Data Store entity identifies store of data, both manual and electronic. Each data store has the following:

A Number A Name A Description One or more input data flows One or more output data flows.

External entity:

The External entity identifies external entities which interacts with the system, usually clients but can be within the same organization. Each external entity has the following:

A Name (Noun) A Description

The different notations to draw DFD are as follows:

RESULTS AND DISCUSSION6.1 Testing:

The aim of testing process is to identify all defects existing in our banking software. However, for most practical system, even after satisfactorily carrying out the testing phase, it is not possible to guarantee that the software error free. This is because of the fact that the input data domain of this software product is very large. It is not practical to test the software exhaustively with respect to each value that the input data may assume. Even with this practical limitation of testing process, we should not underestimate the importance of testing. We must remember that testing does expose many defects existing in the software product. Therefore, we can safely conclude that testing provides a practical way of reducing defects in the system and increasing the users’ confidence in the developed system.

Testing a program consists of subjecting the program to a set of test inputs (or test cases) and observing if the program behaves as expected.

We have tested the project by giving the convenient test cases and it has given the expected results. We have already given it in Design Strategy.

Now we are testing it by giving unfavorable test cases.

47

1. Suppose in a account, the current balance is less than Rs10000,now if we ask for loan than loan will not be approved.

Let account number 3 have balance less than Rs 10000. If it apply for loan the following result will be shown

48

2. If we enter an invalid account number than it will not be entertained.

Suppose account no 5 does not exist and we want to see the details of the account .Then it will give the following result.

49

3. If we ask for loan without having an account then it will show “account not available”.

50

4.If we want to debit an amount which is more than current balance then the following result will be shown

SUMMERY AND CONCLUSION

8.1 Scope Of The Project:

The title of the project is “Banking System” is an application which helps the user to maintain all the work modules included transactions and managing of accounts of the account holders which includes a few hitch due to the absence of real time user and runtime application implementation. Since our first and foremost aim is to satisfy the customer therefore we are going to continue the use, testing, correction, and up gradation of this application as a simultaneous procedure.

This document of scope of the project describes the possible problems to be solved, an opportunity to be exploited, or a benefit that will be achieved in the entire process development.

A fundamental output of the initiation stage is the project scope statement that should include:

Project Justification: The need that the project meant to address.

Project Deliverables: The product/services that the project is meant to deliver.

Project Objectives: What has to be achieved to judge the project a success?

54

Therefore it is necessary to mention the scope of our project at initial step and they are as follows:

The all possible ways of overcoming these problems are like adding a database and maintenance of the same for the customer to provide them with membership facilities, including discounts and special offers on different terms and schemes.

Further scope of edifice of the application is to make it fit to user screen using any operating platform and connecting to a network.

Further looking forward:

The project will include the payroll system of the employees included within the business center. We will further add online and mobile banking fully.

In the absence of real time user in context of this project, it was up to us, the developing team to analyze the requirements for the application and in process, the following was detected:

A procedural flow of user events while alteration of already reserved facility list that shall allow maximum utility with minimum of clicks being made.

The user actions should follow a coordinate track, and must not be discrete. The application structure must be flexible enough to allow expansion and

major updating in future.

8.2 Implementation:

The implementation stage is not so easy. We at first install it then check it for result, so we know that client requirement can be fulfilled or not. Then we

55

implement every module that the overall project can be implemented rightly or wrongly. We see that all the module, i.e. account, user details, transactions are implemented rightly, so the whole project implementation stage we have done rightly.

8.3 Evaluation:

Project Evaluation is a step-by-step process of collecting, recording and organizing information about project results, including short-term outputs (immediate results of activities, or project deliverables), and immediate and longer-term project outcomes (changes in behavior, practice or policy resulting from the project).

Common rationales for conducting an evaluation are:

Response to demands for accountability; Demonstration of effective, efficient and equitable use of financial and other

resources; Recognition of actual changes and progress made; Identification of success factors, need for improvement or where expected

outcomes are unrealistic; Validation for project staff and partners that desired outcomes are being

achieved.

The project planning stage is the best time to identify desired outcomes and how they will be measured. This will guide future planning, as well as ensure that the data required to measure success is available when the time comes to evaluate the project.

Why is Project Evaluation important?

56

Evaluating project results is helpful in providing answer to key question like: What progress has been made?
