Object-oriented analysis and design (OOAD) is a technical approach for analyzing and designing an application, system, or business by applying object-oriented programming, as well as using visual modeling throughout the software development process to guide stakeholder communication and product quality.
Focused on software quality, Eiffel is a purely object-oriented programming language and a notation supporting the entire software lifecycle. Meyer described the Eiffel software development method, based on a small number of key ideas from software engineering and computer science, in Object-Oriented Software Construction. [20]
An object-based language is a programming language that provides a construct to encapsulate state and behavior as an object. A language that also supports inheritance or subtyping is classified as object-oriented . [ 1 ]
Object-oriented modeling (OOM) is an approach to modeling an application that is used at the beginning of the software life cycle when using an object-oriented approach to software development. The software life cycle is typically divided up into stages going from abstract descriptions of the problem to designs then to code and testing and ...
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] The method was authored by Grady Booch when he was working for Rational Software (acquired by IBM), published in 1992 and ...
The listed languages are designed with varying degrees of OOP support. Some are highly focused in OOP while others support multiple paradigms including OOP. [1] For example, C++ is a multi-paradigm language including OOP; [2] however, it is less object-oriented than other languages such as Python [3] and Ruby. [4]
Larman states that "the critical design tool for software development is a mind well educated in design principles. It is not UML or any other technology." [3]: 272 Thus, the GRASP principles are really a mental toolset, a learning aid to help in the design of object-oriented software.
Responsibility-driven design is a design technique in object-oriented programming, which improves encapsulation by using the client–server model. It focuses on the contract by considering the actions that the object is responsible for and the information that the object shares. It was proposed by Rebecca Wirfs-Brock and Brian Wilkerson.
