What is Booch?
Grady Booch's Object-Oriented Design (OOD), also known as Object-Oriented Analysis and Design(OOAD), is a precursor to the Unified Modeling (UML). The Booch method includes six types of diagrams: class, object, state transition, interaction, module, and process.
Booch's Static Diagrams
Booch's class and object diagrams differentiate this methodology (at least in notation) from similar object oriented systems.
