En la actualidad existen distintos motores de persistencia. Estos motores facilitan el mapeo objeto-relacional de atributos entre una base de datos relacional tradicional y suplen la funcionalidad de una base de datos orientada a objetos. Estos motores buscan solucionar el problema de la diferencia entre los dos modelos usados hoy en día para organizar y manipular datos: el usado en la memoria de la computadora (orientación a objetos) y el usado en las bases de datos (modelo relacional). Para lograr esto, estos motores permiten al desarrollador detallar cómo es su modelo de datos, qué relaciones existen y qué forma tienen.
