Introduction

The purpose of this report is to analyze the system requirements essential for the delivery of an effective and ATM system interrelating the customers and the Bank procedures. The aim of this report is to analyze the needs and requirements of the bank, customers, and other relative stakeholders. ATM system is one of the delegating system for the bank and providing better and enhanced services to the consumers and ensuring that the system works efficiently and the user is capable of understanding the procedures and steps involved during the transaction. User interface should be kept at very less complexity level in manner to ensure that the customers and users are easily connecting to the system. This report presents the dataflow diagram at different levels ensuring the exchange of data and information while user is utilizing the banking services. An event response table has also been expressed in this report considering the triggering and ending of the project.

Cycle 1: Events and Structured Analysis with Data Flow Diagrams

A. Event Table Entries

Event	Event Type	Trigger	Activity/Use Case	Response	Destination
Maintenance being maintained for the proper functioning of the ATM machine	Response	ATM technicians uses personal credentials	Maintenance	Allows the technician to integrate and disintegrate the physical parts	ATM technician
Repair the bugs and glitches restricting the ATM from functioning with efficiency	Response	ATM technicians uses personal credentials	Repair	ATM technician would be able to manipulate the software system of the ATM machine	ATM technician
Wants to Swipe the cash card for making transaction with the bank	Response, Image	Customer swipes the cash card in the ATM vending machine	Session	Either allowed to make the transaction or discarded due to expiry of cash card	User
Upgrading the system with new functions	Image, response	ATM technician connect the system to the server	Upgrades	The software can be uploaded as a patch up	New systems will be introduced to the customers
Diagnosing the existing system and identifying the bugs and glitches	Image, response	After verifying credentials by the ATM technician	Diagnosis	ATM technician would be able to analyze the bugs and glitches of the system	ATM technician
Switch on and off	Response	After verifying credentials by the ATM technician	Switch on and off	Technician will managing the switching of thw ATM	ATM tecnician
Cash Card authentication	Image, Response	Swiping the cash card and entering authentication credentials	Authentication	User would be allowed to make the transaction after completing the authentication	User and Bank
Type of transaction, the user wants to make with the Bank	Response, Image	Authentication of the cash card completed and screen shows optional selection for the type of transaction	Type of transaction	The user would be able to get the necessary output	User and Bank
Pin verification by the user input for the transactions	Response, image	Card swiped	Pin Verification	The system will allow the transaction only after the pin verification	User
Depositing money to the bank	Response, image	Pin verified	Deposit	The user would be able to make the deposit and the amount will be reflected in his or her bank account	User
Inquiry about the bank details and transactions made in previous days	Response, image	After pin is verified	Inquiry	The user will be presented with the previous transactions and all other transactions made recently	User and Bank
Transferring the money to another user of same bank or other bank	Response, image	After pin verification is completed	Money transfer	The user would be able to transfer the money into other individual’s bank account	User and Bank
Printing Receipt	Response	After transaction is completed	Print receipt	The user will be terminated from the system and evidence will be provided for the transaction	User

The above diagrams represents the exchange of data and information at level zero emphasizing the user interacting with the banking system or ATM system and making transaction with the bank. The user will have to connect with the bank server for making the transaction and that can be accomplished either through authenticating the cash card or through logging in the bank network.

D. Level 1 Data Flow Diagram

This is level two diagram explaining the additional data flow between the system and the user emphasizing on the delivery of the services being made available to the customers. The level zero diagram explained the simple procedure however; this diagram expresses the data exchange between the database of the ATM, Bank, and utilizing those information, the system will be generating the output.

Conclusion

Based on the above report it can be concluded that the ATM system has been successfully analyzed and proposed diagram effectively presents the relation and data exchange between the customers and the bank. The transaction between the ATM and the Bank has many procedures irrespective of swiping card and taking cash. The above report presented a sophisticated model for the demonstration of the ATM system on which the system will be delivering the necessary operational activities.
