Study Notes
Object-Oriented Modeling in UML Technique
- Object-Oriented Modeling (OOM) using UML provides a visual representation for designing software systems through various diagram types, capturing both static and dynamic aspects.
Static Modeling
- Focuses on the structural elements of the system, including classes, attributes, methods, and relationships among them.
Class Diagrams
- Serve as a blueprint detailing the system's structure.
- Components include:
- Classes: Fundamental entities in the system with attributes and operations.
- Relationships: Define interactions such as associations, generalizations (inheritance), dependencies, and aggregations.
- Attributes and Methods: Detail the properties and behaviors of each class.
- Example in a "Library Management System" includes classes like "Book," "Member," and "Librarian," showcasing relationships where a "Member" is linked to multiple "Book" instances.
Dynamic Modeling
- Captures the behavior of the system through object interactions and state changes over time.
Sequence Diagrams
- Illustrate the sequence of interactions between objects.
- Components include:
- Objects: Instances of classes involved in the interaction.
- Lifelines: Indicate the existence and lifespan of objects during interactions.
- Messages: Show communication events including method calls and returns.
- For the "Borrow Book" use case in a "Library Management System," it demonstrates interactions between "Member," "Librarian," and "LibraryCatalog," detailing actions like checking book availability and issuing books.
State Machine Diagrams
- Model the lifecycle and state transitions of an object.
- Components include:
- States: Conditions or modes an object can be in.
- Transitions: Movements between states triggered by events.
- Events and Actions: Define events triggering changes and actions during transitions.
- In a "Library Management System," the "Book" object could include states like "Available," "Borrowed," and "Archived," with transitions based on user actions like borrowing and returning.
Deployment Modeling
- Illustrates the physical deployment of software components on hardware nodes.
Component Diagrams
- Show the organization and dependencies of software components.
- Components include:
- Components: Modular parts of the system with interfaces.
- Interfaces: Define interaction methods among components.
- Dependencies: Indicate relationships between components.
- In a "Library Management System," components like "User Interface," "Database Management," and "Notification Service" exemplify interactions among them.
Deployment Diagrams
- Provide a visual of how software components are deployed on hardware.
- Components include:
- Nodes: Physical or virtual hardware entities like servers or workstations.
- Artifacts: Software components deployed on these nodes.
- Communication Paths: Show network connections between nodes.
