This project which registered in our training in degree on
technology have to permits at the same time to further our knowledge in the

creation of «web site of e-commerce with higher availability and
an online payment with express union mobile» resolve the notions
of web programmation of the bases of data and of concrete networks. Such as the

customers and his orders. To allow the customers to place the orders and to pay
them on line while integrating a system of delivery and payment adapted to the
