Object-Role Modeling Fundamentals

Viac o knihe

Object-Role Modeling (ORM) offers a straightforward, fact-based approach to data modeling, focusing on how objects interact within relationships. It utilizes attribute-free structures called fact types to represent all relevant information, accommodating unary, binary, and ternary relationships. This method enhances clarity and validation through natural expression, making it more semantically stable compared to traditional attribute-based models like Entity Relationship Modeling (ER) and Unified Modeling Language (UML). ORM simplifies the data modeling process for any business domain.
