Normally, developers use the Component Diagram to check out implementation details, break down the system into smaller parts, depict the structural relationship between system elements especially in the case of large-scale complex projects with more advanced technologies.ĭeployment Diagrams are generally used to show users the visual relationship between software and hardware. Furthermore, the relationship between a Class and an Object in software development can be described as the relationship between, for example, the class "Food" and the brand "KFC" or the general class "User" and a specific username called "David" or what else.Ĭomponent Diagrams are used to show in what way the physical components in a system is organized. By using such diagrams, developers can be able to analyze the operations of the system at a particular instant, and check their abstract structure. Object Diagrams can be considered as the screenshot of the instances and their internal relationships in a specific system. The composite structure type is similar to Class diagrams but the former ones represent more detailed individual parts rather than the whole system structure. In reality, you can create classes such as "Sales Account" or "Online User" in business systems, or "Teacher" and "Student" in academic systems.Ĭomposite Structure Diagrams are used to show the internal structure, the behaviors of classifiers, and the relationships between classes in a system. Each class has three basic elements: the class name at the top, the class attributes in the middle, and the class behaviors at the bottom. Users can depict the static structure and identify classes relationship of a system by checking system's classes and attributes. The class diagram is the building block of all object-oriented software systems. It is the most widely used UML diagram sub-category. "Poly" means "many," and "mor" means "form or face." Binding together makes "many forms.” Polymorphism makes you make many attributes and methods from a single method or attribute in a class by method overloading and method overriding concept. You define encapsulation by making getter and setter methods.
In abstraction, you initialize methods in an abstract class and define those methods in the inherited sub-class.Įncapsulation makes you provide security to your properties and methods from the outer world. When you inherit a class from the superclass, you can access the superclass properties, constructors, methods, and objects besides the properties or methods private to the superclass.Ībstraction makes you hide the details of functionalities of a class from a user. Inheritance in OOPs makes you inherit a sub-class from the superclass. Inheritance is the word that we all are familiar with it. The object can be anything from a human to a building, etc. The objects are the real-world entities that the programmers deal with to solve real-world problems. The classes are the data structures that contain the properties, attributes, constructors, or methods. The six main concepts of Object-Oriented programming concepts are. It contains more features than the UMLs before.īefore understanding UML, you should know what Object-Oriented Programming and its concepts are. The current and more advanced version we are using is UML 2.5. However, after this, many versions were released, like 2.1.1, and 2.1.2, etc. In 2005, the UML 1.5 was replaced by the UML 2.0, the more developed and advanced version of its predecessor. The current UML the world is using is UML 2.x. It contains some lackings, so different versions were made after this, like UML 1.2, 1.3, etc. In 1996, UML Partners was organized by Rumbaugh, Jacobson, and Booch to complete the formalities and specifications of the Unified Modeling Language (UML), and finally, in 1997, they published the UML 1.0 draft. The UML is evolving ever since its concept was made. It would pave a meaningful way to exchange information about the model between different tools, and a contract on explanation would be made. It will also model business and other similar processes. The UML will provide software developers a blueprint and other tools for analyzing and designing the software architecture.
The purpose of UML these organizations set is. In 1997, a significant thing recorded as the Object Management Group (OMG) adopted UML as a standard to meet before developing a new system.
The concept of UML was first developed at Rational Software in the late 1900s between 19.
