DEG Frameworks
Motor de aplicaciones php, MVC y POO
Es dificil describir a DEG ya que no es un framework, es un SISTEMA DE APLICACIONES y por tanto no es una aplicación determinada como un cms o un foro, DEG es el sistema con el que se puede realizar todo tipo de aplicaciones web sin importar el alcance que se le quiera dar. A diferencia de otros sistemas donde hay un “motor” definido, DEG no tiene una clase o archivo que sirva de “motor” porque está pensado para que el conjunto funcione como un TODO. DEG está creado con base en el modelo de abstracción de desarrollo de software MVC, el motor de plantillas integrado con el que se facilita el manejo de los idiomas es un solo elemento que gestiona la conexión entre el soft y la vista, para mas info pasen por nuestra web http://proyectodemonia.com.ar -
