Unified modeling language (UML)

- Throughout this course,…we'll be using a few common diagramming techniques…for drawing classes and their interactions.…These diagrams are from something called UML…or the Unified Modeling Language.…UML is not a programming language.…It's a graphical notation for drawing diagrams…to visualize object oriented systems.…For example,…The class diagram gives a very simple…graphical representation of a class.…It has three sections;…the name of the class,…its attributes or fields…and its behaviors or methods.…

It allows me to quickly sketch out an idea that's readable…and understandable regardless…of which programming language I'll be using.…UML includes over a dozen…different types of structural and behavioral diagrams.…Now you should never be asking the question…where can I write some sequence diagrams?…Instead,…you should simply realize…that one would come in handy…when thinking about…or discussing a situation that isn't clear.…For this course,…we'll only be using a few…of the most common types of diagrams…including class diagrams…
