Question

In your own words, describe UML. Identify at least two types of UML diagrams that can be used in software development; describe when these diagrams are used. You are describing the registration process to a group of first time students at Ivy Tech. Realizing that a visual representation would be helpful in your explanation, you decide to use a UML diagram. What diagram do you choose to use? Why?

Answer 1

2 Types of UML diagram are Timing diagram and use case diagram.

1. Timing diagram : These diagrams are generally used to show the process timeline. There main focus is the time of occurrence of the event.
2. Use case diagram ; These diagrams show how a user (or actor in UML terminology)/ actor interacts with the system. There behaviour with the system and how the system will react on their interaction.

For the above scenario I would like to use, use case diagram. I would like to choose it because it will portray how first time students will go through the registration and what all system behaviour will be there. Here timeline is not that important so i would not like to use Timing diagram.
