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.
