Object-Oriented Analysis and Design - Core UML Diagrams
The course module transitions from traditional modeling techniques to the object-oriented paradigm, focusing on Use Case Modeling and Class Diagrams. Key UML concepts such as actors, use cases, relationships, and the essential details of class diagrams, inheritance, and associations are thoroughly explored. This groundwork is vital for understanding and applying UML in modern software applications.

What we have learnt
- Use Case Modeling is crucial for capturing functional requirements from the user's perspective.
- Class Diagrams represent the static structure of an object-oriented system, detailing classes, their attributes, operations, and relationships.
- The relationships of Inheritance and Association are fundamental in designing object-oriented systems.
Key Concepts
- -- Use Case Model
- A use case model captures the functional requirements of a system from the perspective of external actors.
- -- Actor
- An entity that interacts with the system, initiating or receiving value from a use case.
- -- Class Diagram
- A structural diagram that depicts the system's classes, their attributes, operations, and relationships.
- -- Inheritance
- A relationship where a subclass inherits attributes and operations from a superclass, representing an 'is-a' relationship.
- -- Association
- A relationship between two or more classes indicating a logical connection, showcasing how instances of one class are linked to instances of another.
- -- Aggregation
- A weak 'whole-part' relationship where parts can exist independently of the whole.
- -- Composition
- A strong 'whole-part' relationship where the parts cannot exist independently of the whole.
