Design And Implementation Of Fresh Reservation System Based On Django

In recent years,the rapid development of e-commerce has trained people's habit of shopping online.Some traditional industries have started to combine the Internet,the so-called O2O(Online To Offline)or the Internet +.We develop a fresh food booking system.Buyers can get the goods use PC or smart Phone,and they can collect their loved ones,convenient for them to buy next time.The works are as follows:The framework of the system is MVC,which separates the interface and logical processing.Different part communicates with the other by the API.It debases the coupling.Multi person simultaneous development,Orderly,easily,steadily.In terms of functional requirements: we designs "add","modify" and "delete" functions in the collection,shopping cart and order module,that is,the background administrator can manage the goods in his collection and shopping cart for specific users,and can also help them create orders,which is more convenient for some elderly people who do not use smart phones.In terms of performance optimization: On the one hand,the system uses Redis cache technology to improve the speed of hot data access,reduce the pressure of database access,enhance the user access experience,and solve the page fake death phenomenon.This system adopts the high availability cluster design scheme,removes single point service failure,and provides high availability services for users through cluster mode.On the other hand,a new tree directory structure is proposed on the database directory index,which greatly improves the query speed of the system.This system has made some improvements in the storage and search of commodity information.Compared with the traditional algorithm,this system does not need to traverse the entire commodity information table to list all the sub-categories or all the sub-commodities under a certain commodity.It can improve the browsing speed of user commodities to a certain extent.For those who can use computers or smart phones Users can bring them a better user experience.In summary,compared with the general fresh system,the system has done some work in terms of function and performance,which can bring a certain degree of convenience to the groups who can use smart phones and can not use smart phones.
