Input validation (Interface Layer) | - Format validation (e.g. correct phone number, IBAN, postcode)
- Type validation (e.g. only string is allowed)
- Input required
- Value validation (e.g. age >= 0)
- Can we process this value? (e.g. amount > 0)
- Is the value plausible? (e.g. a non-blocking validation rule, are you sure you want to apply for a 10 million Euro mortgage?)
