The Design and Implementation of Meal Ordering System

Based on Android Technology

Abstract

With the constant improvement of science and technology and social economy, people also have increasingly high requirements for the efficiency and convenience of service, thus proposing a higher requirement for the application software on smartphone. A meal ordering system based on Android technology, which can provide a fast and easy ordering function convenient for daily operation, can meet numerous cellphone users’ demand for food ordering and provide a win-win platform for both demand sides.

This system is exactly designed for achieving online meal ordering on cellphone, and involves the following relevant technologies: Android platform, MySQL technology, Java language. It mainly achieves functions of food ordering, seat selection, my order, manual service, menu management, and user management. After registration, the users can fulfill the functions of food ordering and menu browsing by logging in the client. The operational test indicates that: this system is complete in function and smooth and steady in operation, and has certain value of commercial utility. In the process of design and development, several technological problems are analyzed and solved, which consolidates and deepens the knowledge learned during undergraduate study.
