The composite aggregation (colloquially called composition) relationship is a stronger form of aggregation where the aggregate controls the lifecycle of the elements it aggregates. The graphical representation is a filled diamond shape on the containing class end of the line that connect contained class(es) to the containing class.
UML class diagram Composition and aggregation. In object-oriented programming this relationship can be represented with a Unified Modeling Language Class diagram. This has-a relationship is also known as composition. As you can see from the Class Diagram on the right a car "has-a" carburetor, or a car is "composed of" a carburetor.
UML notation for association, composition and aggregation. The graphical notation represents: the property as a typed element in the box of the enclosing class, the association as a plain line between the associated classes, the aggregation as an unfilled diamond on the side of the aggregate and a solid line, the composition as a filled diamond ...
Composition over inheritance (or composite reuse principle) in object-oriented programming (OOP) is the principle that classes should favor polymorphic behavior and code reuse by their composition (by containing instances of other classes that implement the desired functionality) over inheritance from a base or parent class.

PlantUML is an open-source tool allowing users to create diagrams from a plain text language. Besides various UML diagrams, PlantUML has support for various other software development related formats (such as Archimate, Block diagram, BPMN, C4, Computer network diagram, ERD, Gantt chart, Mind map, and WBD), as well as visualisation of JSON and YAML files.
MagicDraw provides transformation of UML models to specific XML Schema and DB models (generic and Oracle DDL) and vice versa, and any to any transformation. [5] Also model-to-model transformations between the same or different meta-models can be defined and run directly in MagicDraw by using the QVT plugin.
UMLet is an open-source Java-based UML tool designed for teaching the Unified Modeling Language and for quickly creating UML diagrams. It is a drawing tool rather than a modelling tool as there is no underlying dictionary or directory of reusable design objects. UMLet is distributed under the GNU General Public License. [1]
ArgoUML is an UML diagramming application written in Java and released under the open source Eclipse Public License. By virtue of being a Java application, it is available on any platform supported by Java SE.
