Class diagram from database diagram

I have the following tables:

local
{
  id_local,
  nombre
}

servicio
{
   id_servicio,
   descripcion
}

subServicio
{
   id_subservicio,
   descripcion,
   id_servicio
}

local_servicio
{
   id_local,
   id_servicio
}

loca_servicio_subservicio
{
   id_local,
   id_servicio,
   id_subservicio,
}

How can I make the class diagram? one class per table? or how do I do? If you would give me an example, they would help me a lot.
