This is a back-end system that supports the marketing and operation of the C-end (Waima WeChat Mini Program) of Meituan Waima business. It includes sub-systems such as 'Supplier Management (SRM), Product Management, Procurement Management (PMS), Warehouse Management (WMS), Transportation Management (TMS), Order Management (OMS), Delivery Fulfillment Management, Store Management, and Financial Settlement'.
