One attribute in a table can be related to another attribute in another table. Thus, the logic connections between tables can easily be established. Los datos son almacenados en tablas de dos dimensiones en forma de renglones y columnas. Las tablas son llamadas relaciones, los renglones "tuples" y las columnas atributos.

By using objects and methods, it is possible to store and share not just the structure of a database object, but also its behavior.

The object-oriented field is an area of database research. En base de datos orientada a objetos, las operaciones de los objetos pueden ser parte de la definición de la base de datos, en lugar de codificarse en forma separada en la aplicación.
