UML Composite Structure Diagram
UML Composite Structure Diagrams reveal how internal parts of a class or component work together, showing the roles, ports, and connectors that shape system behavior.
Instant Composite Structure Diagram Creation
With the AI chatbot, you can transform system descriptions into a complete composite structure diagram within moments. Describe how a component operates, list its internal parts, or outline collaboration patterns, and the AI converts your input into a structured internal layout. Instead of manually arranging parts and ports or defining every connector, you receive a clear, organized diagram that reflects how the element behaves internally.
Refine and Explore Internal Structure Through Conversation
Once the initial diagram is created, you can continue refining it through natural, conversational updates. Add new parts, introduce ports, adjust collaborations, or request alternative internal configurations—all with simple follow-up prompts. The AI revises the connections, reorganizes structure, and redraws the diagram automatically so your internal model evolves as your understanding becomes more precise.

What Is a UML Composite Structure Diagram?
A UML Composite Structure Diagram is a modeling tool used to illustrate the internal makeup of a class, component, or subsystem. It highlights the parts that exist within an element and shows how they interact through ports and connectors. This provides a deeper view of system architecture, revealing how responsibilities are distributed internally and how behavior emerges from collaboration.
By visualizing internal roles and communication paths, composite structure diagrams help you understand the mechanisms behind system behavior. They show how data flows, how tasks are delegated among internal parts, and how components interact at runtime. This makes the diagram especially valuable for modeling frameworks, embedded systems, multi-layered components, or any design where internal coordination is essential.
Key Concepts
Composite Structure Diagram
A Composite Structure Diagram describes the internal structure of a classifier (such as a class or component) and how its parts collaborate to realize behavior. It shows the internal wiring of elements and the flow of information between them, providing insight into how a system’s functionality is achieved internally.
Part
A Part is a role played by an instance of a classifier (often a class) within the context of a containing structure. It represents a component or sub-element that collaborates with others to perform the overall system behavior. Parts may be connected through ports or connectors.
Required Interface
A Required Interface represents the set of operations or services that a component needs from others to function. It defines external dependencies — what the component expects to be provided by another component or system. In diagrams, it is typically shown as a half circle (socket) attached to the component.
Example: A “Payment Processor” component may have a required interface for “Customer Data Service” to access customer information.
Class
A Class is a blueprint for objects that defines attributes, operations, and relationships. In a composite structure diagram, a class may contain parts and ports to represent its internal structure and how it interacts with other elements.
Property
A Property defines a characteristic of a classifier, such as an attribute, association end, or part. In a composite structure diagram, properties represent the structural features of elements, describing what instances can exist and how they relate to one another.
Provided Interface
A Provided Interface defines the set of operations or services that a component offers to others. It specifies how other components can interact with it. Visually, it is represented as a lollipop (circle) symbol connected to the component.
Example: A “Customer Data Service” component provides an interface for retrieving and updating customer records, which can be used by other components like “Payment Processor” or “Order Management.”
