Abstract
Un sistema de computacion para crear un modelo de objeto semántico a partir de un esquema de base de datos relacional existente. El sistema computacional analiza la informacion de catálogo del esquema de base de datos relacional y crea un objeto semántico para cada tabla definida en el catálogo. Para cada columna definida con una tabla, se adiciona un atributo de valor simple al objeto semántico creado para la tabla. Posteriormente, el sistema analiza la informacion de relacion almacenada en el catálogo para crear atributos de enlace de objeto que definen relaciones entre dos o más objetos semánticos, así como para crear atributos de grupo multivaluados y atributos de valor simple multivaluados. Si el catálogo de base de datos no incluye la informacion relacional, se incita al usuario a indicar los objetos semánticos relacionados.
