Object-oriented design (OOD) is the process of using an object-oriented methodology to design a computing system or application. Thus, for object-oriented projects, different sets of metrics have been proposed. Prerequisites The state is distributed among the objects, and each object handles its state data. These classes are commonly refinements of the analysis classes. A set of design classes refined the analysis class by providing design details. OOSE is the first object-oriented design methodology that employs use cases in software design. Object-oriented programming ( OOP) is a programming paradigm based on the concept of " objects ", which can contain data and code: data in the form of fields (often known as attributes or properties ), and code, in the form of procedures (often known as methods ).
