个人记账管理系统mysql 个人记账管理系统uml

目标要求：

一、系统功能简介：个人财务收支管理系统可以将日常收入、支出流水保存起来，随时更新、查询收支记录及收支平衡情况。
二、课程设计要求：
1、采用面向对象的方法进行系统分析与设计，利用 UML 类图绘制分析设计结果。
2、按照时间顺序保存收支记录，所有收支记录保存在磁盘文件当中，系统开始运行时从
磁盘读取数据，退出系统时自动将所有数据写入磁盘文件。
3、系统对用户录入的数据具有一定的容错能力，例如，输入的日期为 2022 年 2 月 29 日，
提醒用户重新录入时间。
4、系统有自动提醒功能：当实时收支平衡数额为负数时，发出超支警示；当实时收支平
衡数额达到预期目标时，提示实现财务自由。
5、系统主菜单样例：
1-添加收入记录
2-添加支出记录
3-查看起止日期内的收入记录
4-查看起止日期内的支出记录
5-查看实时收支平衡情况
6-按照日期查找收支记录
7-按照日期修改收支记录
8-按照日期删除收支记录
9-统计起止日期内的各类别收支情况
0-退出系统

程序设计思路

定义三个类，分别命名为Date，Fee，Manager，Date类里面含有年月日成员变量以及重载的判断时间的>、<、=、≥、≤；Fee类里面含有时间、类型、金额成员变量；Manager类里面含有各种功能的实现，每一次修改数据后都把数据存放到文件中，同时新建一个功能10，以用于目标的设定
