Then the actor enters the item identifier, and then the system monitors the sale line item and presents item description, price, and running total. In the above illustration, the cashier that is an actor starts the new sale. The Implementation of the Cashier and the System Now, we get the developers have made the shifts from analysis to design. See, when the methods add2Cart, getCartSummary, and finish order are called, the interface passed the cartId to the controller three times. The interface passes this information every time as an argument to the controller each time a system command or query needs that information. The actor is the customer that passes his information to the interface just one time. Source: It is the system sequence diagram of a book store. This section will illustrate to you the practical implementations of the System Sequence Diagram. You cannot fully understand the theory of something until you also understand the practical implementation of something.

Step 1: Download and install EdrawMax on your PC. These lines start from the rectangle shape o with an actor. The dashed lines aka, the lifelines, are the events in the system sequence diagram. These events are generated in a sequence or a specific order. Then with the specific event, the system performs the specific task. The interaction or communication of an actor or system to the system is an event. They are the stick-like figures in the diagram. The interaction can be like interacting with the cashier, customer retrieving amount from the ATM or anything. These are the external entities that interact with our system, and the system is created by keeping actors in mind. The black box is a system that is not illuminated to the outside world because they contain inner processes. In a traditional UML, the box depicting a title represents the class or an object but, in System Sequence Diagram, this shape represents the system as the black-box. The essential elements of the system sequence diagram are. Some of the elements that are used in the use case diagram are also as follows here.
