Design And Implementation Of Online Ordering Meal System Based On J2EE

As traditional way of shopping are turning to network development, gradually appeared the increasingly popular new consumption mode "E-Commerce". In order to improve the catering business level or efficiency and to realize the more effective room services than telephone reservation; Online order system has emerged because of demand. Through the investigation and comprehensive analysis on process of the business, combined with the most advanced software development technology, it can realize the network management order. Currently, the online business is in formative period, it also has very big growing space.System not only needs food and beverage catering services through the entire system of management information systems, also need to work all kinds of human services by computer processing, such as a la carte and menu delivery and so on. At the same time, the site is an online ordering system, customers can select businesses provide network, browse the dishes described, a la carte ordering, agreed meal time, dinner or room service, and specify the currency of payment and other services. Thus, the traditional ordering methods are also turning to the Web development, but, the online ordering service is still in formation, growth is still high.The developmental background, significances, aims, function design, system architecture, key techniques, strategies of network security of Online Ordering Meal System were introduced in this paper, then describing the papers related theory knowledge and technology. On this basis, developing the function analysis, architecture design and detailed design. of Online Ordering Meal System. finally, testing the system.Second, application of methods such as object management system developed by the research, demand analysis, using UML unified modeling method to analyze the online order system, the main function module, while a detailed analysis of use cases and gives the Analysis of the UML use case diagram. Then, according to the demand on the system in the analysis of the data model involved in the design, application of data modeling tools to design a scientific management system table structure involved, and gives the relationship between science and technology management system, data model and data model diagram the data dictionary. Designed the data model, designed the data model into physical data model, and implement database applications with Hibernate persistence layer system data mapping between the design. Then, the application of DAO database access layer of the system was further package, through the DAO layer, allowing the specific business logic and persistence layer separation. Meanwhile, according to the system function modules in science and technology management system designed business logic layer in detail. Finally, in the development of system architecture based on the functional modules in detail the design and implementation, while the system deployment and testing, system implementation to obtain the desired effect. Finally, discusses the online ordering system, deployment and testing.Customers can browse meal product introduction, order, be agreed mealtimes, repast in this website; also meals can be sent to them in the website.The foreground of the system is made up of two parts,one is foreground login,the other is the interface of foreground. Foreground interface includes homepage, order process, meal product introduction, online order, information release, the member center and background login,etc. Background region mainly comprises food information management, order management, information management and user management modules.This system is popularized in small and medium-sized catering enterprises. It can optimize the catering business flow and realize the maximization of enterprise value.Meanwhile, it also makes the lowest cost, and finally enhance the competitive advantage in the catering industry.
