a.
Sequence diagram:
Sequence diagram is a tool that represents the way of interaction of objects to accomplish a work. The objects are labeled with the task to be performed. The arrows show the direction of communication. Objects are shown by rectangles.
Use case diagrams:
Use case diagram is a tool to represent the way of interaction of user with system. Rectangle is used to represent the system. Oval is used for interaction of user and system.
Class diagrams:
Class diagrams not only show associations between different classes but also reveal multiplicities of these associations. Classes are shown by rectangles. Here, relationships of classes are shown by lines.

EBK COMPUTER SCIENCE: AN OVERVIEW
- Course: System Analysis And Design , ITMA 411 State refers to an object’s current status. A state transition diagram shows how an object changes from one state to another, depending on events that affect the object. All possible states must be documented in the state transition diagram.In a state transition diagram, the states appear as rounded rectangles with thestate names inside. The initial state represented as a small circle, and it is the point where the object first interacts with the system. Lines used to show direction and describe the action or event that causes a transition from one state to another. The final state represented as a circle with a hollow border.In this assignment you are requested to create State Transition Diagram for the student registration system.

The sales department processes the order by creating a new order object in an empty state. Materials of the order are pulled out of the inventory at the warehouse and the order is set as filled. Products are then shipped by the warehouse. While the Customer receives the order, the sales department prepares the bill. If the customer pays for the bill within a week sales department closes the order. If the customer doesn’t pay the bill within one week the sales department sends a warning to the customer making him defaulter and closes the order in an unpaid state.arrow_forward
