Users select their destinations

Users select their destinations GROUP ASSIGNMENT PART Study the following case study and answer all the tasks listed. An automated ticket-issuing system sells rail tickets as you find in London underground and over ground railway stations. Users select their destinations and can be pay cash the exact amount or input a credit card and a personal identification number (PIN). The rail ticket is issued and their credit card account charged if the ticket was bought using a credit card.

When the user presses the start button, a menu display of potential destinations is activated along with a message to the user to select a destination. Once a destination has been selected, users are requested to input their credit card. Its validity is checked and the user is then requested to input a personal identifier. When the credit transaction has been validated, the ticket is issued. Ambiguities and omissions include: Can a customer buy several tickets for the same destination together or must they be bought one at a time? Can customers cancel a request if a mistake has been made? How should the system respond if an invalid card is input? What happens if customers try to put their card in before selecting a destination (as they would in ATM machines)? Must the user press the start button again if they wish to buy another ticket to a different destination? Should the system only sell tickets between the station where the machine is situated and direct connections or should it include all possible destinations? What type of input device (touch screen vs. keyboard)? Ticket prices Room on train (assumes tickets have times on them) Train departure and arrival times. Do customers buy tickets for a specific train? Or for any trip along the route? (If the latter, then no way to tell if all the seats on a train are sold out, nor can you do seat assignments.)

Requires Destination, credit card number and PIN Pre-condition None Post-condition None Side effects Charge to the customers credit account user requirements definitions The user requirements for a system should describe the functional and nonfunctional requirements so that they are understandable by system users without any technical knowledge. When we write the user requirement we should not write with technical forms, table or diagrams. We should write in simple language with simple table, forms and diagrams. The actors in the system are the passenger, the counter clerk and the reservation system consisting of form processing, reservation, fare computation, ticket processing, ticket printing, collection of fare amount and posting as sub-systems. The passenger is a passive user-actor who initiates the process and obtains the ticket(s), a goal of measurable value. The counter clerk is an active user-actor, who triggers the system and has the role of issuing the tickets with the responsibility of collecting the correct fare amount from the passenger, which is a measurable value. Predesigned and deployed ticket reservation system at the back end is a system actor-user to ensure that ticket processing is done correctly and different system statuses are updated on issuing of tickets. This actor has an active role and responsibility at the back end. system requirements specifications System requirements Specifications are specified using the standard way of these forms. Function: Issuing Ticket Description: Issuing the ticket when the user select their desired tickets and make the correct payment. Inputs: Destination, child or Adult ,Pay by card or cash Output: Their desired ticket to be issued with their payment receipt Requires : Money Pre- Condition: Ticket will be validate between the user current place and the selected destination, Otherwise user will have to pay the penalty fare. a sequence diagram Scenario 1 This diagram shows about the user wants their ticket from the machine. It shows the interaction between user and ticket machine where user puts the requirement to the machine and the machine gives options back to the user. Scenario 2 This diagram shows the user chose the station and the machine give option back to user needs to choose from following option for e.g return ticket which class user wants to travel. After selecting options the user needs to pay for payment machine give option for eg cash or card. If the user choose card the ticket machine need to validate from card user. Scenario 3 This diagram represents a sequence activity when user buy a ticket using credit or debit card. When the user insert the card. The card is validated with the card issuer the validation of the card is returned to machine which then displays the result to the user. If the card is valid then the user need to enter the pin. The validity of the pin is checked. If the pin is wrong user need to try again. Once completed the user account is credited and the ticket along with the receipt to the user. Non-functional requirements The ticket system shall respond to user inputs to provide tickets and charge accounts in a timely manner. The system shall continue to function so long as roll of ticket paper is in the machine, and a network connection is provided for the destination database and credit transactions. Upon receipt of the destination from the user, the database shall be accessed to determine the distance from the units location, to the desired destination, and calculate the appropriate fee. The unit shall then prompt the user to input their card information, and the unit shall verify that the card is a credit card, is valid, and has sufficient credit to be charged. Upon successful verification, the unit shall print a ticket, and return to its ready state, for the next transaction to take place. The reliability this system relies on the durability of the physical user interface, the network connection in the area the system is placed, the size of the ticket rolls that the unit can accept, and the mecha nism for dispensing the tickets. The estimated time for a complete transaction would be about thirty seconds, giving twenty for the user interactions, five for validation and verification of the users account, and five for printing and dispensing the ticket. Use-cases Requirements validation process. Customer inserts her credit card into the ticket machine. card provider checks the card number. Then the machine asks for the pin-code. User enters the pin-code. Then the ticket machine requests database to validate the credit card. Ticket on processes. customer can use the ticket finaly. A semantic data model Impact if when the customer pays cash As the sequence diagram shows, the customer goes to ticket machine, and he is allowed to not have axact amount, the machine will confirm the amount, go through the check process and issues the ticket with receipt.

Media essay comparing Essay

The use of this threat, which suggests cannibalism, something that still horrifies a lot of people, is particularly effective and still used in films such as â€Å"Silence of the lambs†. Pip certainly portrays an effective show of fear. In the 1997 version Finn, rather looks well cared for and certainly able to defend himself. When Robert De Niro enters as Magwitch he does look rather rough and his use of very graphic language is meant to be representative of the fact that he is not well educated where as in the David Lean version even though Magwitch was ill mannered he did not swear. When grabbed by Magwitch Finn doesn’t look quite as scared as he is meant to. He is not able to answer question except to nod or make some gurgling noises as Magwitch’s hand is covering his mouth all the while. As the 1944 version follows the novel closely the convict is able to pick Pip up and place him on a tombstone and tilt him back to a position where he (the convict) is Pip’s only support and the fact that throughout the whole rough treatment he gets from Magwitch he is constantly polite and uses the respectful title â€Å"sir†, when it is quite clear that Magwitch is no gentleman makes the audience feel even more sympathetic towards him. As the 1997 version of the movie is shot at a beach there is no way that Magwitch could have picked Finn up and place him on a tombstone, although in my opinion he could have tilted him back from the boat nearby so that if Magwitch let go he would fall into the ocean. As for body language on the whole I think that Pip was able to demonstrate his fear far better than Finn in the 1997 version. I found the actions and body language of Magwitch equally daunting in both films. In the 1944 version we do not get to see the Convict’s face properly which leads the audience think of him as a very sinister and frightening figure, as on could imagine him in anyway they like. To oppose that we see Pips face quite clearly and the fear etched into it. In the 1997 version we have only a fleeing vision of the convicts face before the camera zooms in on Pips face and w can only see the convict’s hand which is covering his moth. I believe the 1944 version was more successful in creating a Magwitch that was fearsome to all. I believe casting had a hug part to play in this as well, because I had grown p watching Robert De Niro movies and I have seen him appear in many of my favourite movies in the role of many of my favourite characters and it was very hard for me to think of him as the evil and sinister looking Magwitch as I had other impressions from him. On the other hand as the 1944 version was made years before I was born I had no idea who the actors were and I had no impressions of them before I watched the movie and I am sure if I come across a movie with Finlay Currie cast in a different role I would still think of hi as Abel Magwitch. People usually go to movies to escape their reality for a brief spell of time, the fact that David Lean chose to have his cast wearing Victorian customs makes it easier for the audience to feel transported into another era easier than the 1997 version where the director chose to have the costumes modernized along with everything else. On the whole I think that David Leans version of Great Expectations was more successful in creating tension and suspense. The fact that the movie is in black and white and that it portrays grim and harsh surroundings as opposed to the beautiful and sunny location of the 1997 version of the film where it was very hard for me to feel the slightest bit of tension although there was a considerable amount produced by the sudden appearance of the convict I didn’t feel it was enough or that it did any justice to the book which in my opinion is one of the best ever written and nowadays I often come across writers who have tried to reproduce novels the same way Dickens did. I preferred the 1944 David Lean version because I felt it did justice to the book and gratified my expectations in creating a cataclysm of mounting tension.

The Rhetorical Analysis Of Patrick Henrys Speech - 932 Words

March 23, 1775 a group of Virginian delegates gathered in St. John’s Church in Richmond to discuss the ever looming war with the English crown. It was in this Church where Patrick Henry would deliver one of the most influential speeches in the history of America. â€Å"Give me Liberty or Give Me Death† (3). He exclaimed to the sound of thunderous applause, he was trying to inspire a nation to rebel against their British oppressors. His speech was given two weeks before the revolution began and is accredited to inspiring the nation to take up arms and rebel. His appeals to emotion and logic make this a powerful and inspiring speech. Henry starts his speech by establishing his purpose and the urgency of the matter, he is speaking on â€Å"This is no†¦show more content†¦Have we anything new to offer upon the subject? Nothing. We have held the subject up in every light of which it is capable† (2). He restates his point again for emphasis, and he really dri ves home the point that the crown doesn’t care about them, no matter what they do or what they have done nothing will change. This is an emotionally charged speech, â€Å"They tell us, sir, that we are weak; unable to cope with so formidable an adversary. But when shall we be stronger? Will it be the next week, or the next year? Will it be when we are totally disarmed, and when a British guard shall be stationed in every house? Shall we gather strength by irresolution and inaction?† (3). He is trying to inspire a group of men to go to war. That is never an easy task. Henry begins to use emotions to incite the delegates. He appeals to their fears of having the British completely controlling their lives and quartering soldiers in every home. One of the biggest grievances early colonial American had with the British was the quartering act, a law that forced colonists to provide barracks for British troops, that all the colonists were angry about. Henry brought up an issue that many Americans were passionate about, and used it to make people listen to his message. Henry constantly poses these questions â€Å"When shall we be stronger?† or â€Å" Will it be when we are totally disarmed, and when a British guard shall be stationed in every house?† (3).
