CASE ANALYSIS

Scenario

Design a class model for an OTT platform where users redeem voucher codes to activate subscription plans and process payments.

Key decisions

  • Abstract Voucher base class with SubscriptionVoucher and PromoVoucher subclasses
  • RedemptionService as orchestrator validating vouchers and charging payment gateway
  • Multiplicity captures one user initiating many redemption transactions

When to reuse this

Use when modeling voucher-based access control, subscription activation, or payment orchestration in streaming apps.
