4.6.2 Class Diagram
4.6.2 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. • The class diagram is the main building block of object oriented modeling. • It is used both for general conceptual modeling of the systematic of the application, and for detailed modeling translating the models into programming code. • Class diagrams can also be used for data modeling. • The classes in a class diagram represent both the main objects, interactions in the application and the classes to be programmed. …show more content…
It is printed in Bold, centered and the first letter capitalized. • The middle part contains the attributes of the class. They are left aligned and the first letter is lower case. • The bottom part gives the methods or operations the class can take or undertake. They are also left aligned and the first letter is lower case.
