Internet Bank SoftwareĪ sequence diagram is an alternative way to understand the overall flow of the control of the program. The sequence diagram is very simple and has immediate visual appear this is its great strength.
The horizontal ordering of the life line is arbitrary. The label also can include the argument and some control information and show self delegation, a message that an object sends to itself by sending the message arrow bunch to the same lifeline. Each message is labeled with the message name. The order in which these messages occur is shown top to bottom on the page. Internet Bank SoftwareĮach message is represented by an arrow between the life line of two objects. An object role is shown as a vertical dashed line the life line. However, a sequence diagram does not show the relationship among the roles or the association among the object. An object is shown as a box at the top of a dashed vertical line. The life line represents the object existence during the interaction. The Vertical line is called the object life line. (ii) Horizontal dimension – represents different objects
It shows the object participating in the interaction by their life lines and the messages they exchange arranged in a time sequence. A sequence diagram shows an interaction arranged in a time sequence. Sequence diagram are an easy and intuitive way of describing the behavior of a system be viewing the interaction between the system and its environment. (i) Sequence Diagram Online Banking System:
There are two kinds of interaction models. Interaction diagrams capture the behaviour of a single use case, showing the pattern of interaction among objects. To design the sequence and collaboration diagram for bank process algorithm using rational rose.ĭescription:Interaction diagrams are diagrams that described how groups of object collaborate to get the job done.
