Study Notes

UML Diagrams

UML Diagrams are used to visually represent system architecture, design, and implementation in software development.

Types of UML Diagrams

UML Diagrams can be broadly classified into two categories: Structural UML Diagrams and Behavioral UML Diagrams.

Structural UML Diagrams

Class Diagram: the most widely used UML diagram, depicts the static structure of a system, showing system’s classes, methods, and attributes.
Composite Structure Diagram: represents the internal structure of a class and its interaction points with other parts of the system.
Object Diagram: a screenshot of instances in a system and their relationships, depicts behavior when objects are instantiated.

Component Diagrams

Used to represent how physical components in a system are organized.
Models implementation details.

Deployment Diagrams

Represents system hardware and software.
Shows what hardware components exist and what software components run on them.

Package Diagrams

Depicts how packages and their elements are organized.
Shows dependencies between different packages and internal composition of packages.

Behavioral UML Diagrams

State Machine Diagram: represents the condition of the system or part of the system at finite instances of time.
Activity Diagram: illustrates the flow of control in a system and steps involved in the execution of a use case.
Use Case Diagram: depicts the functionality of a system or part of a system and its interaction with external agents (actors).
Sequence Diagram: depicts interaction between objects in a sequential order.
Communication Diagram: shows sequenced messages exchanged between objects.
Timing Diagram: a special form of Sequence diagram, depicts the behavior of objects over a time frame.
Interaction Overview Diagram: models a sequence of actions and simplifies complex interactions into simpler occurrences.

Creating UML Diagrams

Involves a systematic process that typically includes several steps.

UML Best Practices

Unified Modeling Language (UML) is a general-purpose modeling language that defines a standard way to visualize system design.
UML is not a programming language, but a visual language.
