We have a subscription system. The purpose of the subscription system is to process subscription transactions against a subscription master file. There are three types of transactions: new subscriptions, renewals, cancellations. Each transaction is first validated and then processed against the master filo. For new subscriptions, a customer record is built, and a bill is generated for the balance due. For renewals, the expiration date is updated, and a bill is generated for the balance due. For cancellations, the record is flagged for deletion, and a refund is issued. Draw a HIPO diagram(You don’t need to draw IPO for all functional components. Choose a particular functional component and then show the IPO for only that component.) (25 points)
