Component Diagrams

A Component Diagram in Modeldraw is a structural diagram that shows how components are wired together to form larger components or software systems. It illustrates the structure of arbitrarily complex systems and the interfaces between different parts of these systems.

With Component Diagrams in Modeldraw, you can:

• Visualize the high-level structure of your software system

• Show the organization and relationships between components

• Illustrate the interfaces provided and required by each component

• Demonstrate how components are grouped into packages

• Model the physical aspects of your system, such as files, libraries, and executables

• Facilitate system design and architecture planning

Key Components

• Component

• Ball (Interface Realization)

• Socket (Required Interface)

• Interface

• Package

Component

Represents a modular part of a system with a well-defined interface. Components are the fundamental building blocks in component diagrams, representing functional elements of the system that provide and use interfaces.

Ball (Interface Realization)

Represents an interface that the component provides or implements. It's typically shown as a small circle on the edge of a component, indicating a service or capability that the component offers to other components.

Socket (Required Interface)

Represents an interface that the component requires from other components. It's typically shown as a semicircle or "socket" on the edge of a component, indicating a dependency on an external service or capability.

Interface

Defines a set of operations that characterize the behavior of a component. It can be represented as a circle (provided interface) or a semicircle (required interface) connected to components, or as a separate element with operations listed.

Package

Used to group related components and interfaces together. Packages help organize the diagram and show the logical structure of the system.
