UML 2 Component Diagrams

description
UML Component Diagram Cheat Sheet: http://goo.gl/Ybhhu Welcome to my tutorial on UML 2.0 Component Diagrams! Blocks of code are set up as components to create reusable blocks of code. Component diagrams are then used to show how components are used to create software systems. On top of covering every symbol associated with component diagrams I decided to also cover Composite Structures. They model how objects work together when a class diagram doesn't cut it. Also relationship arrows are covered again because of your requests.

It explains the usage of the dependency relationship arrow to indicate that a class depends on something external, not a member of the class itself.", 'Illustration of association relationship where a class contains a reference to another class or class object, such as a dog having a specific breed. It illustrates the association relationship by using the example of a dog having a specific breed, where the class contains a reference to another class or object.', 'Clarification of aggregation as a situation where a class is a container for other classes, but if the container itself is destroyed, the contained object is not. It clarifies the concept of aggregation by explaining that it involves a class being a container for other classes, and if the container is destroyed, the contained object remains unaffected.']}, {'end': 1070.598, 'start': 598.631, 'title': 'Composite structures in class diagrams', 'summary': 'Discusses composite structures in class diagrams, explaining the relationship between classes and their components, the use of composite structures to model how objects work together, and the documentation of instances and relationships within composite structures.', 'duration': 471.967, 'highlights': ['Composite structures model how objects work together, showing how different parts of a class interact and are documented, such as product, description, picture, user guides, and company name.
