Intro made by Prince Ly Cesar The Data Flow Diagram (DFD) represents the flow of data and the transformations in Automated Teller Machine System. These transformations occurs as data enters and exits a system. In the DFD, input, processing, and output are used to represent and define the overall system. The following are the flows that the System can generate: Managing Customers Information Managing Deposits Information Manage Credit Records Monitor Withdrawal Information Generate Receipts Here’s the DFD levels 0 1 2 for ATM (Automated Teller Machine) System and step-by-step way on how to create ATM system Data Flow Diagrams. ATM (Automated Teller Machine) System DFD Level 0 To start with, let us familiarize what is ATM (Automated Teller Machine) system level 0. The ATM system level 0 is also known as context diagram. It’s supposed to be an abstract view, with the mechanism represented as a single process with external parties. This DFD for the ATM (Automated Teller Machine) system depicts the overall structure as a single bubble. It comes with incoming/outgoing indicators showing input and output data. In this data flow diagram you will see the general process done in ATM (Automated Teller Machine) monitoring. This will also serve as a guide as you go through the deeper processes of the ATM system data flow diagrams. As you see, when you build the levels of data flow diagrams, the connections of the transactions and data also broadens and gets more specific. ATM (Automated Teller Machine) System DFD Level 1 Next to the context diagram is the level 1 data flow diagram. The content of ATM (Automated Teller Machine) System DFD level 1 must be single process node from the context diagram and is broken down into sub processes. In this level, the system must display or reveal further processing information. The following are essential data to accommodate: • Monitoring Withdrawing Records • Customer Information • Transactions • Deposit Information These procedures require information such as record of customers, deposits, balance inquiry, credits and withdrawals from which served as the bases for ATM machines and bank admin to manage the ATM system. This type of data is represented by a data store. With being knowledgeable about the DFD level 1 of the ATM (Automated Teller Machine) System, you will know then its broaden context terms. In addition to that, this may also serve as your reference on how the inputs or data fed on the system. Then you will be also informed about the outputs that the system gives. These processes shown in the DFD were all based on the concept of ATM (Automated Teller Machine) System. ATM (Automated Teller Machine) System Level 2 After presenting the ATM system DFD levels 0 and 1, next to that is level 2. Here’s what you need to consider in creating data flow diagram level 2 for ATM (Automated Teller Machine) system. • The Level 2 DFD for the system should represent the basic modules as well as data flow between them. • Since the DFD level 2 is the highest abstraction level, its ATM system processes must be detailed that is based on the DFD level 1. Finally, after figuring the processes given in the system, the user will now have their request being processed. The Processes that the system should prioritize are as follows: • Managing Customers Information • Managing Deposits Information • Manage Credit Records • Monitor Withdrawal Information • Generate Receipts DFD level 2 let’s you know the ideas on where does the data inputs goes and inputs comes within the ATM (Automated Teller Machine) System. Considering the the dataflow levels mentioned above, you can determine well the importance of breaking the processes into more specific manner. The presented level not only shows you the detailed processes of system, but also gives you precise destination of the data that flows in the system. This DFD will also be your references as you make and design your own project DFD levels 0, 1 and 2. So that completes our discussion fellas! And I hope that this PDF about ATM (Automated Teller Machine) System Data Flow Diagram Levels 0 1 2 | Best DFD 2021 will help you a lot. Now let me ask you something. What have you learned through the discussion? May this article help you with your projects in the future!
