Booch method

The Booch method^[1] is a method for object-oriented software development. It is composed of an object modeling language,^[2] an iterative object-oriented development process,^[3] and a set of recommended practices.^[4]

Class diagram

The method was authored by Grady Booch when he was working for Rational Software (acquired by IBM), published in 1992 and revised in 1994. It was widely used in software engineering for object-oriented analysis and design and benefited from ample documentation and support tools.^[5]

The notation aspect of the Booch methodology was superseded by the Unified Modeling Language (UML), which features graphical elements from the Booch method along with elements from the object-modeling technique (OMT) and object-oriented software engineering (OOSE). Methodological aspects of the Booch method have been incorporated into several methodologies and processes, the primary such methodology being the Rational Unified Process (RUP).^{[citation needed]}

Content of the method

The Booch notation is characterized by cloud shapes to represent classes and distinguishes the following diagrams:^[6]

Model	Type	Diagram	UML correspondence
Logical	Static	Class diagram	Class diagram
		Object diagram	Object diagram
	Dynamic	State transition diagram	State chart diagram
		Interaction diagram	Sequence diagram
Physical	Static	Module diagram	Component diagram
		Process diagram	Deployment diagram

The process is organized around a macro and a micro process.^[1]

The macro process identifies the following activities cycle:

• Conceptualization : establish core requirements
• Analysis : develop a model of the desired behavior
• Design : create an architecture
• Evolution: for the implementation
• Maintenance : for evolution after the delivery

The micro process is applied to new classes, structures or behaviors that emerge during the macro process. It is made of the following cycle:

• Identification of classes and objects
• Identification of their semantics
• Identification of their relationships
• Specification of their interfaces and implementation
