# Database & Website Review

## Database Schema Review ✅

### Tables Created:

1. **users** table
   - Stores: `id`, `full_name`, `username`, `email`, `password`, `total_balance`, `currency`, `created_at`
   - ✅ Username stored
   - ✅ Password stored (hashed)
   - ✅ User data complete

2. **accounts** table
   - Stores: `id`, `user_id`, `currency`, `balance`, `created_at`
   - ✅ User balance stored per currency
   - ✅ Linked to users via foreign key

3. **transfers** table
   - Stores: All transfer details including `user_id`, amounts, currencies, recipient info, status, dates
   - ✅ Transaction history stored
   - ✅ Linked to users via foreign key

## Data Flow Review ✅

### 1. User Registration/Login:
- ✅ User creates account → stored in `users` table
- ✅ Password hashed → stored in `users.password`
- ✅ Default account created → stored in `accounts` table with balance 0

### 2. Dashboard Display:
- ✅ `/api/dashboard` endpoint fetches:
  - User info (id, full_name, username, email) from `users` table
  - Accounts from `accounts` table
  - Total balance calculated from `accounts` table
  - Recent transfers from `transfers` table (last 10)

### 3. Dashboard Page (`dash.html`):
- ✅ Displays user balance from `data.totalBalance`
- ✅ Displays user name from `data.user.full_name`
- ✅ Displays user initials from `data.user.full_name`
- ✅ Displays transaction history from `data.recentTransfers`
- ✅ Shows transactions from `transfers` table

## What's Working:

1. ✅ **User Data Storage**: Username, password, email all stored in database
2. ✅ **User Balance**: Stored in `accounts` table, displayed on dashboard
3. ✅ **Transaction History**: Stored in `transfers` table, displayed on dashboard
4. ✅ **Data Connection**: All data flows from database → API → Dashboard

## API Endpoints:

- ✅ `POST /api/login` - Authenticates user, creates session
- ✅ `GET /api/dashboard` - Returns user data, balance, transactions
- ✅ `POST /api/transfer/lock-rate` - Creates transfer record
- ✅ `POST /api/transfer/confirm` - Completes transfer, updates balance

## Everything is Connected! ✅

All user data (username, password, balance) and transaction history are properly stored in the database and displayed on the dashboard page.
