This is the 22nd day of my participation in the August More Text Challenge
Preface:
This project is to use Java swing development, which can realize the restaurant order system login/register/reset to restaurant meals, the administrator can information management, add a package, the package information maintenance, modification, and to track the status of order, order information processing, process control, query and modify the password, cancel to exit the and so on several big modules. Users can log in to view the package information. Order operation and view order status, brief introduction of interface design, suitable for Java beginners design and learning technology.
Abstract:
With the development of the catering industry in our country, because the restaurant industry threshold is low, most of China’s food and beverage enterprise boss started in a shop, the majority of family management, many or the “rule of man”, did not have a set of modern enterprise system and the supervision and management system, so from concept, management thought and management level has yet to be professional. With the improvement of people’s living standard, the catering industry plays an increasingly important role in the service industry. Striving to stand out in the increasingly fierce competition in the current catering industry has become the goal pursued by every catering operator. Network ordering has realized the cost-effectiveness of small stores as big as to solve the problem of small stores and can not improve the turnover, is a small investment big effect of the new business model. Today, after the popularization of computers, China has entered the Internet information age, and the way of life and the pace of work have become rapid with the speed of information transmission. From mail delivery to Email, from traditional telephone communication to IP telephone network, all the behaviors originally belonging to the real life are slowly transferred to the network, traditional shopping is also developing to the network, the emergence of “online shopping”, a more and more popular new consumption way. Similarly, as a pillar of the service industry, the catering industry inevitably tends to network development.
Main modules:
User login, registration, and reset
Administrator: package information maintenance, query, modify and delete operations, order information query, modify process status, modify password, etc
Client: view package information, order operation, view order status, modify password, etc
Function screenshots:
Log in to register
Add package information
The administrator click Add package information, input relevant information, select pictures and so on to complete the addition
Add result:
Description Succeeded in adding a data to the database
Package information maintenance:
The administrator can enter the package maintenance page, perform fuzzy data query according to the package name and price range, and modify or delete the package by selecting the package information
Order Management:
The administrator can enter the order management page, query the order data and status process according to the order information, and modify the transportation status of the order
Change password:
Enter the old password. After the authentication succeeds, enter the new password twice to change the password
User order page:
Add to shopping cart:
Order submission success:
View order status and cancel order operations:

Copy the codeConclusion:
Through this course design. I learned a lot of knowledge which benefited me a lot. It feels like Java interface design is similar to MFC. It’s just that Java is too much work without a visual interface. Others are mostly class and object problems. It’s pretty simple to implement. Using a database mysql with high stability and security, the two software together to complete the design and development of the system. Also fully consider the needs of users,. The operator can query all the information at any time, and each module provides the information browsing function. This system realizes the online ordering system website consumption customers can search through the system to their own needs of the package information, buy their own needs of the package, online order. And then by the online ordering system background to deal with the relevant order information, such as information. Due to my lack of knowledge and experience and short time in the development process, there will be some defects and deficiencies in the system. In the future, more efforts will be made to improve this system, but it is still a good choice as a reference for students and curriculum design.
