UML Activity Diagram

UML Activity Diagram

UML Activity Diagram is a type of UML diagrams, which illustrates the business and operational step-by-step workflows of components within a system and shows the overall flow of control. UML Activity Diagram is constructed from a limited number of shapes, connected each other with arrows. The most important shape types are rounded rectangles, diamonds, bars, black circle, encircled black circle. The arrows represent the order in which activities happen and run from the start towards the end. ConceptDraw PRO software enhanced with Rapid UML solution is ideal for software designers and software developers who need to draw the UML Activity Diagrams and other types of UML diagrams. It is convenient to use the appropriate stencils of UML notation from the UML Activity library included to the Rapid UML solution of ConceptDraw Solution Park and containing a lot of specific vector UML objects. Use them to design your own UML Activity Diagrams, make them colorful and attractive with style tools of ConceptDraw PRO software. Read more
This example of bank ATM UML activity diagram was created on the base of UML use case diagram of automated teller machine from the course "Thinking in Java, 2nd edition, Revision 9" by Bruce Eckel published on the website of the Computer Science and Electrical Engineering Department of the University of Maryland, Baltimore (UMBC).
"If you are designing an auto-teller, for example, the use case for a particular aspect of the functionality of the system is able to describe what the auto-teller does in every possible situation. Each of these “situations” is referred to as a scenario, and a use case can be considered a collection of scenarios. You can think of a scenario as a question that starts with: “What does the system do if...?” For example, “What does the auto-teller do if a customer has just deposited a check within the last 24 hours, and there’s not enough in the account without the check having cleared to provide a desired withdrawal?”
Use case diagrams are intentionally simple to prevent you from getting bogged down in system implementation details prematurely...
Each stick person represents an “actor,” which is typically a human or some other kind of free agent. (These can even be other computer systems, as is the case with “ATM.”) The box represents the boundary of your system. The ellipses represent the use cases, which are descriptions of valuable work that can be performed with the system. The lines between the actors and the use cases represent the interactions.
It doesn’t matter how the system is actually implemented, as long as it looks like this to the user."

"An automated teller machine or automatic teller machine" (ATM) (American, Australian, Singaporean, Indian, and Hiberno-English), also known as an automated banking machine (ABM) (Canadian English), cash machine, cashpoint, cashline or hole in the wall (British, South African, and Sri Lankan English), is an electronic telecommunications device that enables the clients of a financial institution to perform financial transactions without the need for a cashier, human clerk or bank teller.
On most modern ATMs, the customer is identified by inserting a plastic ATM card with a magnetic stripe or a plastic smart card with a chip that contains a unique card number and some security information such as an expiration date or CVVC (CVV). Authentication is provided by the customer entering a personal identification number (PIN). The newest ATM at Royal Bank of Scotland allows customers to withdraw cash up to £100 without a card by inputting a six-digit code requested through their smartphones.
Using an ATM, customers can access their bank accounts in order to make cash withdrawals, get debit card cash advances, and check their account balances as well as purchase pre-paid mobile phone credit. If the currency being withdrawn from the ATM is different from that which the bank account is denominated in (e.g.: Withdrawing Japanese yen from a bank account containing US dollars), the money will be converted at an official wholesale exchange rate. Thus, ATMs often provide one of the best possible official exchange rates for foreign travellers, and are also widely used for this purpose." [Automated teller machine. Wikipedia]
