This analysis is also done for an existing system. The most important purpose of OO analysis is to identify objects of a system to be designed. Thus, it is important to understand the OO analysis and design concepts. Design means collaboration of identified objects. OO can be defined as an investigation and to be more specific, it is the investigation of objects. Polymorphism − It defines the mechanism to exists in different forms. Inheritance − Inheritance is the mechanism of making new classes from existing ones. Objects − Objects represent an entity and the basic building block.Ĭlass − Class is the blue print of an object.Ībstraction − Abstraction represents the behavior of an real world entity.Įncapsulation − Encapsulation is the mechanism of binding the data together and Thus, before learning UML, it becomes important to understand OO concept in detail.įollowing are some fundamental concepts of the object-oriented world − UML diagrams are representation of object-oriented concepts only. UML is powerful enough to represent all the concepts that exist in object-oriented analysis and design. Objects are the real-world entities that exist around us and the basic concepts such as abstraction, encapsulation, inheritance, and polymorphism all can be represented using UML. The hierarchy is represented as inheritance and the classes can also be associated in different ways as per the requirement. A class describes an object and they also form a hierarchy to model the real-world system. The data represents the state of the object. UML can be described as the successor of object-oriented (OO) analysis and design.Īn object contains both data and methods that control the data. The conceptual model of UML can be mastered by learning the following three major elements − It helps to understand the entities in the real world and how they interact with each other.Īs UML describes the real-time systems, it is very important to make a conceptual model and then proceed gradually. To understand the conceptual model of UML, first we need to clarify what is a conceptual model? and why a conceptual model is required?Ī conceptual model can be defined as a model which is made of concepts and their relationships.Ī conceptual model is the first step before drawing a UML diagram. In conclusion, the goal of UML can be defined as a simple modeling mechanism to model all possible practical systems in today’s complex environment. Thus it must be clear that UML is not a development method rather it accompanies with processes to make it a successful system.

The system can be a software or non-software system. UML diagrams are not only made for developers but also for business users, common people, and anybody interested to understand the system. There are a number of goals for developing UML but the most important is to define some general purpose modeling language, which all modelers can use and it also needs to be made simple to understand and use. At that point of time, there were no standard methodologies to organize and consolidate the object-oriented development. Object-orientedĬoncepts were introduced much earlier than UML. Goals of UMLĪ picture is worth a thousand words, this idiom absolutely fits describing UML.

After some standardization, UML has become an OMG standard. UML has a direct relation with object oriented analysis and design.

UML is not a programming language but tools can be used to generate code in various languages using UML diagrams. For example, the process flow in a manufacturing unit, etc. It is also used to model non-software systems as well. UML can be described as a general purpose visual modeling language to visualize, specify, construct, and document software system.Īlthough UML is generally used to model software systems, it is not limited within this boundary. UML is a pictorial language used to make software blueprints. UML is different from the other common programming languages such as C++, Java, COBOL, etc. UML stands for Unified Modeling Language. OMG is continuously making efforts to create a truly industry standard. UML was created by the Object Management Group (OMG) and UML 1.0 specification draft was proposed to the OMG in January 1997. UML is a standard language for specifying, visualizing, constructing, and documenting the
