UML models software systems in detail; flowcharts represent general logic flow, often less formal.

Common tools include StarUML, Lucidchart, Draw.io, Visual Paradigm, and Enterprise Architect.

It represents inheritance, where a child class inherits properties from a parent class.

It’s a boolean expression controlling whether a transition can occur in a UML diagram.

It organizes classes into packages, showing dependencies and relationships between them.

Stereotypes extend UML elements with custom properties, shown using << >>.

UML helps visualize, specify, construct, and document software system components effectively and clearly.

Composition is a strong “whole-part” relationship where parts cannot exist independently of the whole.

Swimlanes divide responsibilities among actors or departments in activity diagrams.

Yes, UML supports agile by visually modeling user stories, interactions, and architecture components.

It shows object interactions in time sequence, emphasizing message exchanges between components.

It models the flow of control or data in a business process or system operation.

Notes add descriptive text or comments to UML diagrams for clarification or documentation.

It models the states of an object and transitions triggered by events.

An actor represents a user or system that interacts with the application externally.

It illustrates software components, their organization, dependencies, and interfaces in the system.

UML has structural, behavioral, and interaction diagrams for different software design perspectives.

UML is a standardized visual language to model software system architecture, design, and processes.

It represents system functionality through interactions between users (actors) and the system (use cases).

Association is a generic relationship; aggregation represents whole-part with independent lifecycles.

It shows hardware nodes and software artifacts deployed on them in the system architecture.

There are 14 types, categorized into structure and behavior diagrams.

It shows system classes, attributes, methods, and relationships between classes in object-oriented design.

It displays object instances and their relationships at a specific system state or moment.

A constraint specifies conditions or restrictions on UML elements, often expressed in OCL (Object Constraint Language).

A Class Diagram shows the static structure of a system by depicting its classes, their attributes, operations, and the relationships among objects. It serves as a blueprint for the system's data model. ​

These terms describe relationships between classes:

• Association: A general connection between classes.​
• Aggregation: A specialized form of association representing a whole-part relationship.
• Composition: A stronger form of aggregation where the child cannot exist without the parent. 

A Sequence Diagram illustrates how objects interact in a particular scenario of a use case, detailing the sequence of messages exchanged between objects over time.

A Use Case Diagram represents the functional requirements of a system by illustrating the interactions between actors (users or external systems) and the system itself. It provides a high-level view of system functionality. 

A Deployment Diagram represents the physical deployment of artifacts on nodes, showing the hardware configuration and the software components deployed on those nodes.

A Package Diagram organizes the elements of a system into related groups to minimize dependencies among them, aiding in system modularization. 

UML (Unified Modeling Language) is a standardized modeling language used to visualize, specify, construct, and document the artifacts of a software system. It provides a comprehensive way to represent system architecture, behavior, and interactions.​

A State Diagram shows the states an object can be in and the transitions between these states, triggered by events. It models the dynamic behavior of a system. ​

A Component Diagram illustrates the organization and dependencies among a set of components in a system, helping to visualize the system's modular structure. ​

An Activity Diagram represents the flow of control or data in a system, modeling the dynamic aspects of the system by depicting the sequence of activities. 

Multiplicity defines how many instances of one class can be associated with instances of another class in a UML Class Diagram. It helps specify cardinality constraints, such as one-to-many or many-to-many relationships.

A Timing Diagram is a type of UML Interaction Diagram that focuses on the behavior of objects over time. It shows changes in state or condition and helps model real-time systems or embedded software.

UML diagrams help in visualizing system architecture, specifying system behavior, designing software components, documenting system design, and analyzing system requirements, thereby enhancing understanding and communication among stakeholders. 

UML diagrams are categorized into two main types:​

Structural Diagrams: Class Diagram, Object Diagram, Component Diagram, Composite Structure Diagram, Deployment Diagram, Package Diagram.​

Behavioral Diagrams: Use Case Diagram, Sequence Diagram, Activity Diagram, State Diagram, Communication Diagram, Interaction Overview Diagram, Timing Diagram.

Interaction Diagrams like Sequence Diagrams and Communication Diagrams help visualize the flow of messages between objects. These diagrams are essential in understanding system behavior during runtime and are widely used in object-oriented analysis and design.

The building blocks of UML include things (such as classes, objects, and components), relationships (such as associations and dependencies), and diagrams (such as class diagrams and sequence diagrams).

A Composite Structure Diagram shows the internal structure of a class and the interactions between its parts. It is useful in complex systems where a class includes other objects or roles within it.

The Use Case View in UML focuses on the functional requirements of the system, representing the interactions between actors and the system through use case diagrams.

UML provides a standardized way to visualize system design, enhances communication among team members, supports software system construction and documentation, and helps in analyzing system requirements. 

In Use Case Diagrams:​

Include: Represents a situation where a use case contains the behavior of another use case.​

Extend: Indicates optional behavior that can extend the base use case. 

Object Diagrams represent instances of classes at a specific point in time, showcasing real-world examples. In contrast, Class Diagrams define the blueprint for those instances, including attributes, methods, and relationships.

UML is utilized in various phases of the software development lifecycle, including requirement analysis, design, implementation, testing, and maintenance, to facilitate communication, design, and documentation. 

Popular UML tools include Lucidchart, Visual Paradigm, StarUML, Enterprise Architect, and draw.io. These tools support modeling various UML diagram types and often integrate with development environments.

UML Profiles allow customization of standard UML by extending it with stereotypes, tagged values, and constraints. They are especially useful in domain-specific modeling, such as SysML for systems engineering or SoaML for service-oriented architecture.

Swimlanes are used in UML Activity Diagrams to group activities by the responsible actor or organizational unit. This visual aid clarifies responsibilities in a process flow, making it easier to interpret complex workflows.
