Dennis's Online Ordering System Design And Realization

The Denis Logistics is the maximal logistics of Henan province centre at present,who has 13 large supermarket chains and build the Intemet web form of orders. It simplifies the transfer process orders, procurement staff from the peak of orders sent out relief work; Suppliers can know the time to sell the cargo information at home.The thesis Analysis the subject that the orders of the existing system to switch to the web platform in the database, in addition, the thesis also discusses the data processing and data transmission problems. The server data exchange has set up between the MIS system and the WEB system in order to the security of data. The data exchange between the Dissimilar databases needs another way , which is using the database rollback or other error handling, we have to enter to log the error when the computer can not determine the problem, Administrators can manually amended and procedures for its amendment.We solve the following practical issues under the collaborative of the research group:First, the problems of order display and printing on web database platform. The order must meet the requirements of the format and achieve the print-related features. At the same time, the system record of orders that be printed, We need to print the defmition of regional WEB pages when we print the order, and swap shield the region that is not related.Second, the problems of MIS system orders data into a logistics system in the purchase order data and data transmission. WEB logistics system different from the system placed on the Internet, which is part of their internal network and has the security issues.In order to protect the security of data ,We need to deal with encryption when the data is transmitted, and then decrypte when the data reach their destinations, and then import data. The process of data import also need to ensure the integrity of the data,the system has rollback,logs, and other technical means of prevention. Third, the problems of the data into a single shipment of MIS in the receipt of data and data transmit. Logistics System produce shipping documents when received MIS system orders needs, At the same time the goods Come to the stores, the system need to update the intemal data for the logistics system to produce documentation of receipt when received the goods. we also need to send encrypted In data transmission, the data will be decrypted at the receiver.
