Object-role modeling (original) (raw)
- Object Role Modeling (ORM, englisch für Modellierung der Rollen von Objekten) dient dazu, im Rahmen der Datenmodellierung einen Ausschnitt der realen Welt (englisch universe of discourse, UoD) zu beschreiben. Es beschreibt Objekte und ihre Rollen zueinander entweder in einfachen Sätzen, oder in intuitiven Diagrammen. Es dient zum einen in der konzeptionellen Phase der Anwendungsentwicklung der Verständigung zwischen Anwendern und Entwicklern, wobei ausschließlich das Was, also die Sachlogik, und nicht das Wie, also die Technik, dargestellt wird. Zum anderen dient das ORM-Modell in der Implementierungsphase als Grundlage für das Design der Datenbank. (de)
- Modela de objeto-rol (ORM) es usado para modelar la semántica de un universo de discurso. ORM es a menudo utilizado para modelado de datos e ingeniería de software. Un modelo de rol de objeto utiliza símbolos gráficos basados en la lógica del primer orden y la teoría de conjuntos para permitir al modelador crear una definición inequívoca de un universo arbitrario del discurso. Libre de atributos, los predicados de un Modelo ORM se prestan al análisis y diseño de modelos de bases de datos de grafos en tanto que ORM fue concebido originalmente para beneficiar el diseño de bases de datos relacionales. El término "modelo de objeto-rol" estuvo acuñado en el 1970 y las herramientas ORM han sido utilizadas para más de 30 años principalmente para modelado de datos. Más recientemente ORM ha solido modelo reglas empresariales, XML-Schemas,almacenes de dato, ingeniería de requisitos y formulario web (es)

- Object-role modeling (ORM) is used to model the semantics of a universe of discourse. ORM is often used for data modeling and software engineering. An object-role model uses graphical symbols that are based on first order predicate logic and set theory to enable the modeler to create an unambiguous definition of an arbitrary universe of discourse. Attribute free, the predicates of an ORM Model lend themselves to the analysis and design of graph database models in as much as ORM was originally conceived to benefit relational database design. The term "object-role model" was coined in the 1970s and ORM based tools have been used for more than 30 years – principally for data modeling. More recently ORM has been used to model business rules, XML-Schemas, data warehouses, requirements engineering and web forms. (en)

- Object role modeling of kortweg ORM is een methode voor het ontwerpen en het bevragen van conceptuele datamodellen, waarin de toepassing is beschreven in door niet-technische gebruikers te begrijpen termen. In de praktijk brengen ORM datamodellen meer werkregels in kaart en zijn deze makkelijker te valideren en aan te passen dan datamodellen van andere benaderingen. (nl)
