Software Engineering - Object-Oriented Design: Relationships, Interactions, and Process
The module focuses on the advanced aspects of Object-Oriented Design (OOD), covering important relationships between objects such as association, aggregation, composition, and dependency. It emphasizes the significance of dynamic modeling through Interaction Diagrams and illustrates the development of Sequence Diagrams to capture temporal interactions. The chapter culminates in understanding the structured OOD process integrating various UML diagrams to construct robust software architectures.

What we have learnt
- Differentiate between types of associations such as association, aggregation, composition, and dependency.
- Understand the purpose and construction of Interaction Diagrams within OOD.
- Master the process of developing Sequence Diagrams to illustrate dynamic interactions in software design.
- Recognize the key components and notation of State-Machine Diagrams for modeling object behavior.
- Comprehend the iterative Object-Oriented Design process that emphasizes the use of UML diagrams.
Key Concepts
- -- Association
- A general relationship between classes indicating that instances of one class can interact with instances of another class.
- -- Aggregation
- A 'whole-part' relationship where the parts can exist independently of the whole.
- -- Composition
- A stronger form of aggregation indicating that parts cannot exist independently and are exclusively owned by a whole.
- -- Dependency
- The weakest relationship where one class relies on another only temporarily.
- -- Sequence Diagram
- A type of UML Interaction Diagram emphasizing the time-ordered interactions between objects.
- -- StateMachine Diagram
- A diagram that models the states of an object and the transitions between those states based on events.
