Mapping objet-relationnel
Un mapping objet-relationnel (en anglais object-relational mapping ou ORM) est une technique de programmation informatique qui crée l'illusion d'une base de données orientée objet à partir d'une base de données relationnelle en définissant des correspondances entre cette base de données et les objets du langage utilisé. On pourrait le désigner par « correspondance entre monde objet et monde relationnel »
