How a Distributed Family Finance System Simplifies Home Budget Management

Introduction

The distributed family finance system is a classic information‑management solution designed to centralize fragmented household consumption and investment data from various online platforms, enabling family members to manage assets more efficiently and conveniently.

Backend Architecture

The backend is built with MySQL and Java, leveraging a Spring Cloud micro‑service architecture to implement user, income/expense, stock, fund, asset, debt, and monthly/annual report services.

Frontend Implementation

The frontend uses Node.js and Ant.Design Pro to provide user‑friendly interactions, allowing operations such as recording and visualizing household income and expenses, dynamic stock and fund queries with charts, managing purchased assets, and generating month‑end and year‑end financial reports.
