ATM withdrawal process – UML sequence diagram example (2024)

FAQs

Can you explain an UML sequence diagram for ATM? ›

The sequence diagram illustrates how a bank customer interacts with an ATM to withdraw cash. This client inserts the card and the ATM checks the bank database to confirm the card's validity. Next, the client inputs their PIN, and the database confirms it is correct.

STEP-1: Go to an ATM kiosk with your card. You don't need to visit the ATM of your bank, all cards work at all ATMs. STEP-2: Insert the card in the ATM slot in the correct way. Some ATMs keep your card in the slot while you continue the transaction, while some give it out after reading it.

Using an ATM is simple. You need to insert your ATM card into the machine's card slot with the chip or magnetic stripe facing up and toward the machine. Next, enter your 4-digit PIN. Now, select the language and transaction type and follow the instructions on the screen to complete your transaction.

The Withdraw Money use case allows users to withdraw cash from their account using the ATM. The user selects the withdraw money option, enters the desired amount, and the machine dispenses the cash. This use case is a vital feature of any ATM system as it allows users to access their funds easily and conveniently.

As per the updated regulations from the RBI (Reserve Bank of India), with effect from 1st January 2022, users of most banks can withdraw cash from ATM five times per month. These five transactions are inclusive of both financial and non-financial (balance inquiry, mini statements etc.)

The first interaction is simple. The user inserts the bank card into the ATM. Type “user” and then create a labeled arrow to explain the message that is going from the user to the ATM.

What is the purpose of the sequence diagram in UML? ›

The sequence diagram is used primarily to show the interactions between objects in the sequential order that those interactions occur. Much like the class diagram, developers typically think sequence diagrams were meant exclusively for them.

Lock up and take your keys with you. Remove your cash, receipt, and card after every transaction. If you make a withdrawal, pocket the cash immediately. Be discrete and don't expose or count your money until you are in a safe place.

Bank staff will usually start with the transaction data and look for likely indicators of fraud. Time stamps, location data, IP addresses, and other elements can be used to prove whether or not the cardholder was involved in the transaction.

This ATM Object Diagram is an important behavioral diagram in the UML diagram for describing the system's dynamic aspects. These Activity Diagrams are frequently used in business process modeling, for example, to demonstrate how an ATM withdrawal works.

UML class diagrams contain classes and their interactions. Each class is shown in a rectangle with, from top to bottom, the class name, its attributes, and its methods. Only the class name is required. The level of detail needed determines whether the attributes and methods are shown.

A sequence diagram is a type of interaction diagram because it describes how—and in what order—a group of objects works together. These diagrams are used by software developers and business professionals to understand requirements for a new system or to document an existing process.

A UML diagram is a way to visualize systems and software using Unified Modeling Language (UML). Software engineers create UML diagrams to understand the designs, code architecture, and proposed implementation of complex software systems. UML diagrams are also used to model workflows and business processes.
