Cersei Lannister, the evil queen of Seven Kindoms cast a spell (I know this is not Harry Potter-Just go with the flow) that erased all the information that was stored in the servers across Winterfell. After casting a protective spell on Winterfell, Ned Stark has decided to reconstruct the databases and he hires a team of database designers and developers and – Guess what? Youâ€re hired. You are involved with a project that involves designing and constructing a database for all the cinemas in Winterfell. Although all the data was lost, Ned Starkâ€s son (Rob Stark) who owns a cinema himself manages to provide you a set of information regarding the working of Cinemas across Winterfell. This is what is given to you: WORKING OF CINEMAS . 1) There are various cinemas across Winterfell. The Cinemas could be contacted using Email and Phone number provided on their website
(Think about Event Cinemas, Hoyts Cinemas, etc and relate to those as you go along). . 2) These Cinemas have different branches which screen the movies (Think about how Event Cinemas has a cinema at MQ Shopping Centre) . 3) The Cinema usually provides the following information about Movies: Name, Year Released, Language, Classification (PG/MA etc) . 4) Every Cinema has specific number of screens and there is a particular seating capacity for every screen . 5) The screen is usually added to a roster and thatâ€s how a schedule of which screens display what movies are recorded.
BOOKINGS BY CUSTOMERS . 1) Customers can go online or make a booking in-queue in the cinemas . 2) Whilst making a booking(online and in-queue), the information about the customer
(Name, Address, Phone Number) are saved for any future reference . 3) If Customer decides to obtain a membership, other information like email address,
credit card details are also saved . 4) All cinemas offer memberships- every membership incurs a monthly fee and offers a
discount for every booking . 5) Customers can book a more than one seat while making a booking. . 6) If a customer decides to make an in-queue booking, employee id gets recorded in the
booking details. . 7) Employee details are recorded too by the Cinemas (Name, Address, Contact number,
etc) After giving the above information, Rob Stark left to fight a battle leaving you with options to make your own assumptions (he is a network-free battlefield). If you are making assumptions, list them down in an Appendix Section. page2image23888.png ¬page2image24048.png ¬ 2) Task Specifications 1) Task one (8 marks) Construct an Enhanced E-R model for the above case using any drawing tools.
