If the homework assignments, can save up enough,
If it is the actual business needs, but also collect customer information, VIP hierarchical, different levels of discount level and dock with the sales system, in addition to collecting VIP consumption habits, according to the consumption habit of the VIP (often consumption place, often consumer goods categories, often spending time, etc.) for promotional push...

If the homework assignments, don't want to answer,
If it is real business system, think the original poster or consider to buy ready-made or outsourcing,
