In the digital era, information systems play an essential role in supporting the operational process of modern organizations. Among the critical phases of software development, conceptual modeling remains one of the most decisive, especially during the early stages, when system requirements are still being explored and formalized. The heart of conceptual modeling lies in the use of diagrammatic notation, with the Unified Modeling Language (UML) class diagrams emerging as one of the most widely adopted standards for representing the static structure of object-oriented systems. These diagrams enable designers to abstractly represent classes, their attributes, and interrelations such as associations, generalizations, and aggregations, providing a visual formalism that facilitates analysis, communication, and software specification.
