If you are familiar with the basics regarding the UML relationships, you can continue reading the rest of the article. Otherwise, first have a look at the basics of relationships in UML . Now, let’s have a look at the advanced information that can be represented using the above relationships: Dependency The dependency relationship is also known as using relationship i.e., if the specification of one thing (for example Graphics class code) changes then it will automatically affect the behavior of another thing (for example Hello class using the drawstring method of Graphics class) that uses it.
