A metaclass is used in object oriented programming and is typically thought of as a classes class. A class embodies the properties and behaviour that a collection of objects have in common. Like most meta information, the metaclass works behind the program and is never seen by the user. Objects in ooad things are objects that indirect in the system.

Thus, the metaclass of the root class is an instance of itself. In analysis developers work with users and domain experts to define what the system is. The name of a class should reflect its intrinsic nature. Specifically, we define the interchange syntax with a mofbased metamodel and the graphical syntax with a qvt mapping to a graphics metamodel. Just knowing how to draw uml diagrams or create models does not imply good ooaood. Object oriented analysis and design object oriented analysis and design ooad is a software engineering approach that models a system as a group of interacting objects. Modeling software systems using uml2, wiley dreamtech india pvt. The uml definition is deeply confused about the meaning of semantics the semantics section is mostly about abstract syntax the semantics section contains subsections called semantics the notation section contains paragraphs called semantics each of these sections deals, in natural language, with a variety of things. In these languages, classes are firstclass objects, meaning they can be used exactly like any other. Object oriented analysis is a process that groups items that interact with one another, typically by class, data or behavior, to create a model that accurately represents the intended purpose of the system as a whole.
Guidelines for naming classes the class should describe a single object, so it should be the singular form of noun. Ooad is a software engineering approach that models and designs a system as a group of interacting objects. Cs8592 syllabus object oriented analysis and design.

Business process lifecycle consists of five stages.
These objects are typically modeled after real world entities or. Object oriented analysis and design pdf notes ooad pdf. Perhaps most important, we offer you fresh approaches to reasoning about complex systems. Your contribution will go a long way in helping us. Audience this tutorial has been designed to help beginners.
The main difference is that object do the work in system, they do not just store the information i. Each object represents some entity of interest in the system being modeled, and is characterized by its class, its state data elements, and its behavior. In this semester, metuclass will be used for the announcements. The ood process takes the conceptual systems model, use cases, system relational model, user interface ui and other analysis data as input from the ooa phase. This is used in ood to identify, define and design systems classes and objects, as well as their relationship, interface and implementation. Since metaclass objects do not behave differently you cannot add class methods for a metaclass, so metaclass objects all have the same methods, they are all instances of the same classthe metaclass of the root class unlike smalltalk. In practice, the definition or specification of a class includes the definitions of the attributes comprising the state, the methods implementing the behavior, and how to handle creation and destruction of an object. The use of modeling to define and analyze the requirements necessary for success of a system. An object in object oriented approach is often similar to a data entity in the traditional approach.
