Explain relationship with its different types.

Relationship:

• A relationship describes how different parts of a system relate to each other.
• It’s a way to visually represent the connections and dependencies between elements in a model.
• They provide a clear understanding of how various components in a system work together.
• Relationships help in representing the structure and behavior of a system in a more comprehensive way.

Types of Relationship:

1. Dependency Notation:
   • What it does: Describes which elements in a UML model depend on each other.
   • Representation: Shown with a dotted arrow.
   • Arrow Head: Points to the element that is independent.
   • Use: Indicates a connection between two elements in a system.
2. Association Notation:
   • What it does: Describes how elements in a UML diagram are associated or connected.
   • Representation: Shown with a dotted line, possibly with arrows on both ends.
   • Ends of Line: Represent the associated elements.
   • Multiplicity: Indicates how many objects are connected (e.g., 1, *, etc.).
3. Generalization Notation:
   • What it does: Describes the inheritance relationship in an object-oriented world (parent and child relationship).
   • Representation: Shown with an arrow having a hollow arrowhead.
   • Ends of Arrow: Represent the parent and child elements.
4. Extensibility Notation:
   • What it does: Enhances the capabilities of the UML language by allowing extensions in syntax, semantics, etc.
   • Mechanisms: Uses stereotypes (for new elements), tagged values (for new attributes), and constraints (for boundaries).
   • Use: Enables the language to adapt and extend its functionality.
