Short Definition: A composite relationship means that a class cannot exist by itself. It must exist as a member of another class. A composite relationship is indicated by a solid line with a solid diamond head pointing to the part class. Alternatively, you can show this relationship graphically with the part class nested in the whole class.

Short Definition: Where you generalize specific classes into general parent classes or take general parent classes and specialize them as needed in child classes. A Generalization relationship is the equivalent of inheritance in object oriented programming (OOP). A Generalization relationship is an "is-a" relationship and is indicated by an arrow with a hollow arrowhead pointing to the parent class. For example, a Honda Accord "is-a" Car.

Short Definition: DFDs document a process by documenting the flow of data throughout the process. They depict how data interacts with a system. They can be used to engineer a new process, document an existing process, or re-engineer an existing process. Traditional Data Flow Diagrams use four (4) symbols, a square, an arrow, a circle, and parallel lines.

Short Definition: In UML 1.x, many UML users referred to the UML diagrams as UML Artifacts. Starting with UML 2.0, a UML Artifact is defined as a physical unit, such as an application executable, database, file, script, etc. Only artifacts live on physical nodes; classes and components do not have "location."

Short Definition: An actor is a person or system that fills a role and interacts with another system. An actor supplies a stimulus to the system.
When establishing actors of your system, do not think in terms of a specific person, think in terms of their role. Do not name an actor the name of the person filling the role. If Bob is our Sales Clerk, name your actor Sales Clerk (not Bob).
