Design And Implementation Of Cross-Platform Automatic And Multi-person Shared Financial Management System

With the diversification of people's consumption channels,mobile payment is becoming more and more popular.In addition,as the cost of living is gradually increasing,there are more and more scenarios for sharing expenses such as multi-person sharing and entrepreneurship.The financial management on the Android platform has the problems of long operation path and easy omission.The cross-platform automatic and multi-person shared financial management system is proposed to meet the needs for cross-platform financial management,multi-person shared financial management,as well as automatic financial management and category intelligent classification on Android platform.This project has completed the design and implementation of cross-platform automatic and multi-person shared financial management system.First,through background introduction,technical research and selection,this paper explains the necessity and research basis of system,and determines that the system's front-end framework uses React Native,API design uses Restful specifications,back-end uses Go language and Echo framework,the database uses PostgreSQL,and the intelligent classification uses deep learning algorithms.Then,this paper explains the functional and non-functional requirements of system through application scenarios and role analysis.The system functions are divided into four modules:login/registration,personal financial management,multi-person shared financial management,automatic financial management and intelligent classification.The software design part explains the system architecture design,database structure design,function module design of this system,and the process of intelligent classification module based on deep learning.The software implementation part describes the system implementation process from three parts:back-end Web service implementation,back-end intelligent classification implementation,and front-end application implementation.The intelligent classification includes the text classification module based on deep learning.According to the characteristics and technical investigation of POI data in the demand,system implements the intelligent classification based on the CNN deep learning model.Finally,this paper describes functional and non-functional test cases based on requirements analysis and output execution results.The system has passed the test case and meet the needs of cross-platform financial management,multi-person shared financial management,as well as automatic financial management and category intelligent classification on Android platform.The deep learning model of intelligent classification has a high classification accuracy rate after parameter tuning.Therefore,the financial management system implemented can cover wider range of scenarios,and effectively reduce the Android user's operating path,thereby achieving the purpose of saving user time and convenient financial management.
