Shippers Drug Stores (SDS), which consists of a chain of retail stores across Canada, wants to be able to provide a new online customer service system. Each store has an identifying store number, an address, phone and email. The company dispenses a wide range of pharmaceutical (drug) products. Each product has a name as well as a unique DIN (Drug Identifying Number). Each store keeps its own inventory record which maintains information on the quantity of each product that is on hand as well as its reorder level and reorder quantity

A major feature of the new system will enable customers to request a refill for a prescription on file with Acme. They can do so by selecting the medication needed by entering the 7 character RX# of their prescription. This information is on the label printed on the dispensed medication. For security purposes they will be prompted to also enter their date of birth. Basic customer data will already be on file from when the prescription was originally presented. The prescription details will be displayed to the customer. If there are no refills left on the prescription the customer will be advised to contact their physician and their request will be terminated. If sufficient refills are available the customer will be asked to confirm the refill.

A refill request transaction will be created with a unique request id and stored for dispensing purposes with the date and time of the refill request. The date and time for picking up the medication that the system has calculated will also be included in the transaction and displayed to the customer.

Other services provided by the system require that the customer be registered To register the customer enters their health card no and their date of birth. Once the system has retrieved and displayed the existing customer data, the customer will create and input a password. In addition, they will then select a security question from a random one presented to them by the system and will then provide their answer. Both the question and answer will be retained by the system

A registered customer can go online and display all their current prescriptions. This will show the following information: the date it was issued, the name of the medication, its RX#, the unit of measure and quantity dispensed, and the number of refills remaining.

Optionally from this list a customer may select a prescription and then schedule a date for an automatic refill or they may decide to transfer a prescription from one store to another.

The customer can repeat these actions for multiple prescriptions individually in the same session

Pharmacists at the stores will access the refill requests transactions stored in the system which will be displayed to them in priority sequence to dispense based on the scheduled pickup date and time provided to the customer. When a prescription is filled the date it was filled is recorded and the central inventory record is updated with the quantity used. The no of refills recorded against the prescription is also decremented
