They play a crucial role in the design and documentation phases of software development, helping teams communicate effectively and streamline the design process. What are Class Diagrams? Class diagrams depict the static structure of a system, illustrating how classes interact with one another. In these diagrams, classes are represented as boxes divided into three compartments: Class Name: The name of the class is centered and bolded in the top compartment. Attributes: This compartment lists the class’s data members, including visibility (public, private) and data types. Methods: The bottom compartment outlines the class’s functions or procedures, detailing visibility, return types, and parameters. Lines connecting the class boxes indicate associations between classes, visua
