Dependency (Method Access)

Description

• Represents a relationship where one class relies on another class, but changes in the dependent class do not affect the independent class.
• Shown as a dashed line with an arrow pointing from the dependent class to the independent class.
• Indicates that a change in the independent class might impact the dependent class, but not vice versa.

• The Food relation is a Dependency
• The Address relation is the Association
