Ejercicio de Repaso

Ejercicio integral modelado de procesos, datos y DER.

Dado que la idea es mantener  “al cliente” el mayor tiempo posible  dentro del portal de e-Business, la solicitud de datos del mismo se difiere hasta el momento previo al pago, ya sea para solicitar la identificación del cliente o bien de registrar el alta correspondiente si se trata de uno nuevo.
Por tal razón, todo el proceso de venta electrónica  se inicia con la selección de artículos que realiza el cliente en el portal Web de la empresa, eligiendo los diferentes ítems que conforman “la compra” y adicionándolos al correspondiente carrito.
Finalizada la selección de artículos, y confirmada su existencia en stock, se le solicita al cliente su identificación para el caso de estar ya registrado, caso contrario se procede al alta del nuevo  cliente, solicitando datos personales de nombre, domicilio, país, ciudad, direcciones de entrega, etc.
