Features include:
Add, edit, and delete transactions automatically
Query totals and category-specific expenses, e.g., “How much did I spend on food this month?”
Generate financial summaries and monthly reports
Automatic ID assignment and date handling

| id | Unique sequential identifier (auto-incremented) |
| type | "income" or "expense" |
| value | Monetary value (format: 1234.56) |
| category | Classification of the transaction |
| payment\_method | Payment method used (e.g., card, cash, PIX) |
