An Introduction to Statecharts: Visual Formalism for Complex Systems
By
sph
The bagel they save for the regulars. Don't skim, savour.
Summary
This article introduces statecharts as a visual formalism for modeling complex systems, originally defined by David Harel in 1987. It explains that statecharts are essentially drawings that help software engineers design and understand complex system behaviors. The article covers what statecharts are, how they differ from state machines, their benefits and drawbacks, and provides practical examples of their use in software development.
Key quotes
· 2 pulledA statechart can be explained in many ways, and we'll get to those explanations, but essentially, a statechart is a drawing.
The original paper that defines statecharts bills them as 'A visual formalism for complex systems' (Harel, 1987).
