Abstract
In spite of remarkable progress in computing technology, many businesses struggling with the problem of modeling and accessing data. Although faster and graphical interfaces do help somewhat, they do not address the problem’s fundamental cause. A business is basically a complex, evolving “organism”, about, which we need to communicate efficiently. So, our language for modeling and querying must be clear yet detailed enough to capture the business’s complexity and remain easy to change as the business evolves. ORM being a fact-based modeling tool, is the method used for designing and querying database models at the conceptual level, where the application is described in terms readily understood by users, rather than being recast in terms of implementation data structures. Once ORM is used, information required from the system is transformed into elementary facts, the fact types are drawn and population check applied, entity types are combined and arithmetic derivations noted, uniqueness and mandatory constraints are added, checking logical derivations, value is added with set comparison and sub typing constraints, other constraints are added and then final checks will be performed. Therefore, business modelers should use ORM with their stakeholders in order to explore their problem domain. This is because ORM diagrams are incredibly an effective way to explore domain concepts with stakeholders. Still from the business user perspective, the use of a natural language (e.g. English) would be the strongest reason to use ORM, making it superior to traditional ER and UML modeling languages. In conclusion this research provides a sketch of the ORM method as a modeling language, mentioning its features and touching some of its advantage
