Architecture of YHD

  1. 1. www.vmcd.org by Louis liu Yihaodian Total system architecture Yihaodian (www.yhd.com) is a Chinese online grocery business founded by Gang Yu and Junling Liu on July 2008. Yihaodian is a business-to-consumer (B2C) e-commerce website that provides people with a platform to shop groceries online. Yihaodian has “virtual stores” that exhibit images of stocked grocery shelves on walls and other surfaces in urban public areas in China, which passersby can scan codes under the images with a mobile device to purchase corresponding groceries online. The retail giant Walmart first invested in Yihaodian in 2011; in 2012, it announced additional investment so that Walmart controlled 51% of Yihaodian’s ownership.
