"Unparalleled problems, the Wal-Mart how do? "Likes to challenge them Wal-Mart shops N, is a very great day sales imagine How can we ensure that cross-regional and cross-border large volume of data in real time? ? ? For example : ----------------------------------------------------------------------------------------- Supermarket sales of its products in China a certain date sales Cities : ** 4 1234 05/11/01 21：01：01 100 ------------------------------------------------------------------------------------------ Every minute of a large number of sales data, learned how to present a commodity available in the reservoir? (Real time) ----------------------------------------------------------------------------------------------- Headquarters merchandise sales volume in the reservoir. . . . . ** 1234 25635 21654 ------------------------------------------------------------------------------------------------ This is N times higher than that of course, the use of large quantities of data update can be solved Trigger? Master prawn who missed two strokes, thank you - Meanwhile learning! Unclear, but there should be local cache bars. China's telecommunications network is not broken, not business? Will be at noon at a fixed time data acquisition such work. Most supermarket chains, and are based on the way upstairs But to do so is very difficult to make an accurate analysis of the current value of the Secretary, to challenge the limits of our responsibility is not only the best better We Come How do you know that Wal-Mart outlets, cross-regional and cross-border large volume of data in real time? Why should real-time real-time? Why should cross-border? Wal-Mart has its own satellite network, the network will continue to arise, there are real-time data It is estimated that more than 100 transactions per second, the system now has to deal with not a lot of pressure right up Real-time data need to update? Sales and nothing but bars. Sales in local statistics is a regular. I think it is not declared a global server bars. Real-time transaction data and an update of what is the meaning? Argentina did not need a server, server to read the data across Azerbaijan Satellite network is the most likely -- If there are no satellite network, the result is not achieved by If you open a lot of shops, of course, want to shop in their own right can be informed of the latest situation Could it be said that this technology viable? ? --> Dadeihao, if not an updated one, a point in time would like to know how to deal with the situation in the reservoir? --> This is true? --> Why do you have to know a point in time in the reservoir? Why should know that trans-regional, cross-border point of the reservoir Zhongguancun to know why Wal-Mart shops in the United States shop? Bank of China Telecom, a considerable number of projects are needed 24 hours after inquiry Updated regularly, such as business class after gathering data to update the headquarters technically feasible, it is necessary for management. As each transaction is updated immediately to the headquarters, even if technically feasible, and there is no need for management. No it is impossible to manage the necessary inputs. Retail profits are minimal, particularly supermarkets, the boss regarded input see bogged down. Ordering, purchasing, are monthly and weekly is the fastest local allocation generally 2-3 days, the earliest the next day. Sales data for specific commodities allocation and procurement prepared for the real-time data on each sale, purchase orders meaningless. As for the cashier, accounting and boss, the class had a sufficient number of total sales. To be able to understand business processes and building understanding of the operation of the System. Upstairs say! --> A very good ah, we are concerned, the data is updated regularly, but the relatively small number of shops now it will be several months With the scale has grown at hundreds of times what kind of retail management system able to satisfy our needs? Wal-Mart is not very clear to me how to do, but I can tell you is how do we units. Headquarters room on the server as well as many shops, all with the company in the ERP system, this should be CS ERP structure itself, but to real-time data to update all the shops were recorded using remote desktop connectivity to the server and use ERP (BS feel like structure, but in fact it is not) Who knows? Should have satellite network, but do not know is not real-time There is no authority under 阿~ out Correction Thank you Wal-Mart has his own satellite network, yes, but he will also consider the network interruption I wish he did not have a database supermarket months to deal with this supermarket data in a certain way, there is a data center in the region to preserve the data and then in the core data center to preserve all the information. Not exactly the same levels of data preservation. Supermarket timely data is kept by the database server, a complete record of all the data currently supermarkets, the supermarkets are immediately reflected in every transaction Supermarket database. Poses supermarket and the supermarket can link database calls, if interrupted, poses not proceed with the transaction, and the main types of business oltp. Regional data centers in the region to preserve data. Supermarket data in the database regularly to the region to grasp the data center. Not timely data, but the data were broadly consistent with the supermarket, a relatively short delay, such as one hour or one day. Disaster Recovery could also perform the work, if necessary, and in the region can only afford olap related content, such as analysis of consumer behavior in the region. The main purpose is to connect data centers and supermarkets core data center and the region can only assume olap related business. Core data center that includes all of the data, a greater delay than regional data centers, may reach a few days or weeks. Olap company is mainly responsible for the operational level to provide high-level policy advice, if need be, and a number of data center hearts, interchangeable parts, and bear different business. Wal-Mart has not seen the database network, the above elements are purely speculative Argentina benefited from this here If Wal-Mart can know the process of operation, we can continue to escalate the Kazakhstan ⇒ point increase to continue upgrading Daguai ⇒ ⇒ Daguai ⇒ escalation ⇒ ⇒ point increase. . . . . . . Life-long Learning Retail knowledge on the logistics of the EU can come here --> Banking, telecommunications customer information is updated real-time, I think the pattern of Wal-Mart and financial, insurance, telecommunications, almost. --> Credit card swipe of the card, account, the next day is generally effective. Telephone handset-the charges are only inquiries yesterday. It is important to know why the region, cross-border addition of a real-time reservoir? Wal-Mart, the United States of Wal-Mart stock in real time what is the use? Each of the stocks are limited retail outlets in each major cities have large storage unified deployment. [ Closed window ]
