Khan Sohaib Problem Statement CSCE461 14th September 2001
Interface for Video Store Abstract:
Generation X video store wants to develop a new interface for their store. The need for this arises as there are more and more thefts going on at their store and they want users to use the terminals provided in the store area, look for the desired movie/DVDs themselves on the terminal rather then picking the movie from the shelves and then ask at the counter for the movie.
User's Work Context:
The user log in to the terminal either by giving username and password or by scanning the membership card. If the user is registered the system lets the user on the main screen. If the user is new the system asks the user to open a new account and after that the user is directed to the main screen. If the user knows what item is need then the user gives the system that input and then goes to checkout if the item is in stock if not then the user is asked to give another choice. At all times the user can logout of the system regardless of buying or renting the items. There is also search option with different criteria for searching for the item needed by the user. There is also an option for is the user wants to read the review of the certain movie/DVD or see the trailer after the search or input given by the user for the item also if the required item is not in stock but the user wants the movies for sure, user can ask to mail the movie to certain address. This option can be used to special interest movies that are not available generally. When the user is done, checkout screen comes up which will ask the user for more movies or go to payment screen. Here the user is asked for either this item is to be rented or buying, in both cases the payment screen comes up and user can pay by different method (credit card, checks) or the user can open up a debit account and charge there membership cards which can be used as a method of payment. After payment is made the user logs out of the system. Proceeds to the pickup counter, picks up the movies or any other item selected by the user. Administration can log on to the same system, but the user context here will be different as compared to the costumer's user context. The staff can log in to the system and add/ remove movies in to database either by writing in the required fields or by scanners. Also the working staff has access to the costumer accounts to ensure security, smooth handling or other issues to be taken care of. Easy reversible of action are provided at every step to accommodate any mistakes also help is available for new users The problem at hand can be expanded with the time.
Interface Overview:
The interface for the users will consists of following parts: 1- Registration for the New users 2- Logging in to the system 3- Searching for movies or DVDs, which in turn provides more option on the search queries 4- The User can read reviews for the certain movies plus other information 5- Handling of the User Accounts 6- Ordering of the movie from other store if the movie is not available at the site store The interface for the administration staff will consists of following parts: 1- Viewing the user 2- accounts Adding new movies/DVDs into the inventory 3- Deleting the old movie/DVDs from the inventory
Design Problem/Use Cases:
Registration: The interface provides new users to register for an account with Generation X store. The perk for joining would be that members could get promotional item and discounts. On the designing side the interface would require some personal information from the user and update the database. Credit card number will not be required at the time of registration as the user are going to pay later. Logging in to the system: Logging on to the system can be done either by the membership card or by giving the user name and password. This works well especially if the user doesn't have a card on them they can still log into the system and rent the movies/DVDs. Searching: Searching can be done for the entire items n the store. Two options are given one for movies and the other for DVDs. Then other sub options are given to specify the search criteria for a certain movie or something. Reading reviews: This is optional service provided by the interface. This can be implemented by either giving textual reviews or by playing the trailers provided by the producing companies. Accounts Handling: This will be the major part of the interface design problem. Because of the security of the payment method and other e-commerce issues. The user will check out after renting/buying the certain movie/DVD, the system will check if the account is clear from the past due if so then the user is allowed to proceed otherwise either logout of the system or pay the amount due before renting another. Then payment methods are displayed on the screen. Different options can be given here depending on the implementation of the terminals, after the payment is made the user logs out.
Ordering of the movie from other store The user has the option to order the movie, which is not at the site...
