As analyzed in the previous article, three types of services are provided in the background systems of full-text search, data mining, and recommendation engine: Synchronous service, asynchronous service, and background service. For synchronization services that can use Web Service, XML Over HTTP or Restful services, I used Jason over HTTP in the project, mainly considering the high efficiency of Json parsin

for recognition, it may be due to a mistake. In the past two days, Dangdang has been unable to make a deal with the customer due to incorrect prices. If he wants to provide the price comparison function, the price information must be accurate.
