1.3 Intended Audience and Reading Suggestions The Document is intended for all the customers and the  developers(Designer,Tester,Maintainers)

1.4 Definitions 1.4.1 Definitions • Account

A single account in Freecharge from which transactions can be applied. Accounts can be made using the social media websites such as google account or the facebook account.

One account can be used one at a time only. • Recharge

To charge again, especially to refill the amount for any transactions.. • Bank

A financial institution that holds accounts for customers and that issues cash cards

authorizing access to accounts over the Freecharge . • Marketing

The management process through which goods and services move from concept to the customer. It includes the coordination of four elements called the 4 P's of marketing: (1) identification, selection and development of a product,

(2) determination of its price,

(3) selection of a distribution channel to reach the customer's place, and (4) development and implementation of a promotional strategy.

A card assigned to a Freecharge customer that authorizes access to accounts using an Freecharge account.

national standards on credit cards and cash cards. The bank code uniquely identifies the

bank within the consortium. The account determines the accounts that the responsible person

can access. A card does not necessarily access all of a customer’s accounts. Each cash

card is owned by a single customer, but multiple copies of it may exist, so the possibility

of simultaneous use of the same card from different devices must be considered.

• Customer

The holder of one or more account of Freecharge. A customer can consist of one or more

Persons or corporations, the correspondence is not relevant to this problem.

•Transaction

A single integral request for operations on the accounts of a single customer. We only

specified that Freecharge account must dispense offers, but we should not preclude the possibility ofprinting receipts or accepting virtual cash. We may also want to provide the flexibility

to operate on accounts of different customers, although it is not required yet. The

different operations must balance properly.

 Profile

A short article giving a description of a person or organization.

 Project Scope

The software supports a computerized transaction. The network enables customers to complete simple recharge

services via Freecharge mobile app that may be

located off premise and that need not be owned and operated by the customer’s bank. The ATM identifies a customer by a cash card and password. It collects information about a simple account transaction (e.g., deposit, withdrawal, transfer, bill payment), communicates the

transaction information to the customer’s account details, and dispenses virtual cash transactions

to the customer. The Freecharge provide their own software for their own computers. The Freecharge software requires appropriate record keeping and security provisions. The software must handle concurrent

accesses to the same account correctly.

Data Base

The Freecharge must be able to use several data formats according to the data formats that are

provided by the data bases of different banks and the users. A transaction should have all the properties of

a data base transaction (Atomicity, Consistency, Isolation, Durability).

A Database is collection of related data, which can be of any size and complexity. By using the concept of Database, we can easily store and retrieve the data. The major purpose of a database is to provide the information, which utilizes it with the information’s that the system needs according to its own requirements.

 Database Design:

Database design is done before building it to meet needs of end-users within a given information-system that the database is intended to support. The database design defines the needed data and data structures that such a database comprises.

 The database is physically implemented using MySQL.

MySQL is a relational database managements system

(RDBMS) that runs as a server providing multi-user access to a number of databases.

The database for Insurance System is organized into 7 tables:

DATAFLOW DIAGRAMS

  The Data Flow Diagrams are commonly used during problem Analysis. A DFD is very useful in understanding the system effectively. The DFD shows the flow of data through a system. 

Notations in the DFD:

Symbol Description

The circle or bubble represents a process. A process is named and each process is represented by a named circle.

The source or sink is represented as a rectangular box. The source or sink is the net originator or the consumer of the data that flows in the system.

The arrow represents the flow of data through the system. The labeled arrows enter or leave the bubbles.

The database is represented with the open box symbol

*

The need for multiple data flows i.e AND relationship by a process is represented by * between data flows.

+ The OR relationship between data flows is represented by + between data flows.

Appendix C: Issues List

1. Sometimes the money is deducted from the account but the recharge is unsuccessful. 2. The message prompt is there sometimes that the promo codes is not valid.

3. Questions are arised on the safety of the online recharge. 4. Sometimes there is extra charges for the recharge.
