Please written by computer source The following relation is an extract from a restaurant point-of-sale (POS) system. The system assigns a globally unique id (GUID) to every transaction processed. CheckID comes from the pre-printed check number on the ticket used by the server for the order; these pre-printed tickets are guaranteed to be unique within the restaurant. RegisterID is which register was used for checkout and the date and time of the checkout – to the minute – are recorded in CheckoutDT; assume no two checkouts can occur at the same register in the same minute. PayType and PayTotal are, respectively, how the check was paid and what the total payment was; assume there is no splitting of a check among multiple payments. When answering the questions below use the format [attribute, attribute, …, attribute] to identify keys. 1. How many keys in general (including the empty or null key) are there in this relation? 2. Identity two multi-keys for this relation. 3. Identify two…

Design the database as a single relation called Movie. It should contain an ID, Title, Year Released, Genre (e.g., sci-fi, comedy, thriller, etc.), Rating (e.g., G, PG, R, etc.), Format (e.g., VHS, DVD, MP3, etc.), a free-form Comments field, plus the main cast and crew members. Add the following entry plus at least two of your own: Title: Star Trek Year: 2009 Genre: Sci-Fi Rating: PG Format: DVD Director: J. J. Abrams Starring: Chris Pine (Capt. Kirk), Zachary Quinto (Mr. Spock) Zoe Saldana (Uhura), Karl Urban (Bones McCoy) Draw your corrected design as a logical ERD showing attributes and multiplicities (suggest you use IE Notation in Oracle Data Modeler). No need to include physical data types. Modify the sample data from step 1 in a new page to match this design
