Introduction

• A Sequence diagram depicts the sequence of actions that occur in a system.

• The invocation of methods in each object, and the order in which the invocation occurs is captured in a Sequence diagram.

• This makes the Sequence diagram a very useful tool to easily represent the dynamic behavior of a system.

• A Sequence diagram is two-dimensional in nature. On the horizontal axis, it shows the life of the object that it represents, while on the vertical axis, it shows the sequence of the creation or invocation of these objects.
