Design And Implementation Of Nutrition Data Analysis System Based On Android Platform

In recent years,the potential health hazards caused by dietary structure and nutritional intake have become one of major problems around the world.As an important part of nutrition and health research,there are still many shortcomings in the acquisition and analysis of domestic dietary structure and nutrition data.How to establish a convenient and accurate platform of nutrition data acquisition and analysis,which combines with existing scientific and technological theories,has become an important problem to be solved urgently.With the development of mobile Internet and the rapid improvement of mobile terminals,smart phones play an increasingly important role in people's life.How to apply mobile Internet in the field of nutrition and health is worth to ponder.Considering the above problems and conditions nowadays,this thesis develops a nutrition data analysis system that bases on Android platform,aiming at developing a platform to monitor daily diet and acquire and analyze nutrition data.Firstly,according to the research results and domestic and overseas conditions,this thesis reviews the technology of Android mobile platform and its application development.Then combines with the characteristics of users of this system,including the existing technology,economic conditions and social status,this thesis studies the feasibility of the system,and analyzes the basic business and functional requirements,as well as determines the structure of the system "mobile client-web management client-server client".Subsequently,the overall structure,overall function,two clients' specific functional modules and the classes of the system are designed,and the logical structure of the database is designed.Finally,based on Android mobile platform,adopting MVC software architecture,using HTML5 plus,Java Script,Layui,My SQL and other related technologies,the system has been successfully implemented.And in the mobile client,a hybrid recommendation algorithm is adopted to complete the user's exclusive recipe recommendation,and the system successfully passes the system test.In this system,users can input daily diet,analyze nutrient intake data,inquire and export these data,formulate exclusive recipe and try any other operations.This system can be used as a tool for daily dietary monitoring and nutrition data analysis and collection,and providing reference for users to balance their dietary structure.
