What Is A Class Diagram

It illustrates classes with their attributes operations as well as their statistical and logical inter relationships.
What is a class diagram. In software engineering a class diagram in the unified modeling language uml is a type of static structure diagram that describes the structure of a system by showing the system s classes their attributes operations or methods and the relationships among objects. Learn uml faster better and easier. A class diagram is a type of diagram and part of a unified modeling language uml that defines and provides the overview and structure of a system in terms of classes attributes and methods and the relationships between different classes.
A class diagram is a type of static structural diagram that describes the structure of the system by showing the classes their attributes methods and the relationship among the classes. The class diagram is the main building block of object oriented modeling. The uml notation is a notation conceived for modeling object of applications and continue and extend in particular the notations of omt object modeling technique and booch methods.
An object diagram is also a type of static structural diagram that shows a complete or partial view of the structure of a modeled system at a specific time. Class diagrams are a vital part of any software development project and they form the foundation of all software products. It is used for general conceptual modeling of the structure of the application and for detailed modeling translating the models into programming code.
Class diagram is a static diagram and it is used to model the static view of a system. In this context a class defines the methods and variables in an object which is a specific entity in a program or the unit of code representing that entity. Class diagram defines the types of objects in the system and the different types of relationships that exist among them.
Class diagram is also considered as the foundation for component and deployment diagrams. The class diagram represents the static structure of systems. A class diagram is one of the most important diagrams in the uml notation.
A class diagram is an illustration of the relationships and source code dependencies among classes in the unified modeling language uml. Class diagrams can also be used for data modeling. This modeling method can run with almost all object oriented methods.
