Purchase Videos.

On a weekly basis, the system uses web services provided by the vendors to monitor the availability of new videos for purchase. As each video becomes available, movie review web services are used to estimate their popularity, based on box office sales.

Web services are for programs rather than humans, and they are often based on HTTPS gets and posts and typically transfer XML as a container for data rather than HTML which normally describes a page to be rendered.

Based on these and also based on rental activity for the store, the system recommends a quantity of each video to purchase. An interactive report is generated for the manager which includes these quantities, prices as well as a total price for all of the videos. The manager is able to modify the quantities of each video to purchase. Purchase requests are sent out to the vendors via the vendors web service. A data entry for each copy ordered is created at this point.

Recieve Videos.

When ordered videos are delivered, they are manually processed. This involves:-

Giving each copy an RFID and a barcode.

Registering its RFID and barcode with the system.

New Video Membership.

Authorised staff may process new membership applications. As part of the membership application, prospective customer are required to produce documents to establish two goals:-

Identify the customer.

Confirm that the customer is a local resident.

The staff member records the details of the document, (the drivers license number, for example), and the system uses a points system for each type of document to ensure that the two goals are met.

Expired Video Membership.

Memberships of customers who have not rented videos for the maximum number of months are de-activated.

Video Rentals

Members bring their videos to the counter, payment is accepted for the videos being rented and for any outstanding overdue fees. and the copies of the video are noted in the system as being borrowed by the member. The due date for return of the videos are noted.

Video Returns

The “borrowed” relationship between video members and the borrowed copies is cleared. Members are billed overdue fees at this time when videos are overdue.

Reminder Mailouts for Overdue Videos.

Once per week notification mailouts are sent to members who have videos still borrowed 14 days or more after the due date.

Once per week a report is generated for the manager reporting videos that are 30 days overdue or more, and unpaid overdue fees.
