Description:Interaction diagrams are diagrams that described how groups of object collaborate to get the job done. Interaction diagrams capture the behaviour of a single use case, showing the pattern of interaction among objects. There are two kinds of interaction models. Online Banking System – Rational rose

(i) Sequence Diagram Online Banking System:
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. A sequence diagram shows an interaction arranged in a time sequence. 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 has 2 dimensions,
(i) Vertical dimension – represent time
(ii) Horizontal dimension – represents different objects
The Vertical line is called the object life line. The life line represents the object existence during the interaction. An object is shown as a box at the top of a dashed vertical line. Online Banking System
However, a sequence diagram does not show the relationship among the roles or the association among the object. An object role is shown as a vertical dashed line the life line. Internet Bank Software
Each message is represented by an arrow between the life line of two objects. The order in which these messages occur is shown top to bottom on the page. Each message is labeled with the message name. 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.

The horizontal ordering of the life line is arbitrary.
The sequence diagram is very simple and has immediate visual appear this is its great strength. Internet Bank Software
A sequence diagram is an alternative way to understand the overall flow of the control of the program. Instead of looking at the code and trying to find out the over all sequence of behavior we can use sequence diagram to quickly understand the sequence. Online Banking System – Rational rose diagram
