CASE ANALYSIS

Scenario

A loyalty system where customers earn points via transactions and redeem them for rewards.

Key decisions

  • Separate PointTransaction and Redemption to track earning vs spending
  • Use enumeration for transaction types (EARN, REDEEM, EXPIRE)
  • Derived attributes for totalPoints and runningBalance

When to reuse this

When designing a point-based loyalty or rewards system in e-commerce apps.
