【借贷系统】【数据库】资金流水表&利息表：怎么设计
利息表是物理存在db中的吗？比如a用户入账1w，每月还其利息，那么这每个月的利息是单独的一个物理记录，还完本月利息，此记录就删除。
如果不是物理存在的，就应该是依赖于储蓄表的一个字段咯？每个月更新这个字段，做减额，如果延期，还有很多问题。
流水表需要哪些字段嘞？
/////////
那么流水和利息需要怎么设计表才合理？怎么操作这些表？麻烦哪位前辈有相关资料，麻烦分享下
/////////
其实我个人比较倾向于在初期采取一个简单方法，就是所有借贷发生时静态的在db记录相关信息，事后实际的违约，罚款，还利息，等等这些人工去每天查看，也就不需要数据库定时触发了。个人感觉交易系统是个牛逼的东西

What's going on with vscode not running python
Apr 15, 2025 pm 06:00 PM
The most common "cannot run Python" problem stems from the misconfiguration of the Python interpreter path. Solutions include: confirming Python installation, configuring VS Code, and using a virtual environment. In addition, there are efficient debugging techniques and best practices such as breakpoint debugging, variable monitoring, log output, and code formatting, such as isolating dependencies using virtual environments, tracking code execution using breakpoints, and tracking variable changes in real time using monitoring expressions, etc., which can greatly improve development efficiency.
