Drawing Objects
Software is hard to visualize, especially when classes and their relationships become complex.
Unified Modeling Language (UML) is a way of creating diagrams to represent classes and interactions among them.
We will focus on the class diagram, which shows how things in a system relate to each other.
Practice Exercise¶
UML is an extensive collection of diagram notations and modeling processes for Object-Oriented Analysis and Design (OOAD). It's called "Unified" because it originally combined ideas from several early OOAD pioneers, notably Grady Booch, Ivar Jacobson, and James Rumbaugh. You don't need to know all of UML to write OO applications, but you should be able to recognize the basics of and use some of the key diagram notations.
