Create a set of Tables in 3NF. Underline the Primary Key(s) for each table. Considering labeling foreign keys (fk) to aid in your design.

StayWell also rents out properties on a weekly basis to students attending summer school in the Seattle area. Design a database to meet the following requirements, using the shorthand representation and a diagram of your choice. For each student renter, list his or her number, first name, middle initial, last name, address, city, state, postal code, telephone number, and e-mail address. For each property, list the office number, property address, city, state, postal code, square footage, number of bedrooms, number of floors, maximum number of persons that can sleep in the unit, and the base weekly rate. For each rental agreement, list the renter number, first name, middle initial, last name, address, city, state, postal code, telephone number, start date of the rental, end date of the rental, and the weekly rental amount. The rental period is one or more weeks.

In anticipation of a change to the database, you are asked to provide a list of all products that have 'Man-Made' or 'Man Made' in the the composition text. (HInt: It is easiest to use LIKE in this instance.)  In addition, you are requested to replace either 'Man-Made' or 'Man Made' with the word 'Synthetic'. Only include ProductIDs between 1050 and 1060.  Show the following in your answer: ProductID, ProductName, Composition, and the modified composition field as 'NewComposition'.   (HINT:  This problem is a little tricky because you need to replace both 'Man-Made' and 'Man Made'.  The way to do this is to use a replace within a replace.)

Consider the following schema of hotel reservations database: Hotel (Hotel No, Name, City) Room (Room No, Hotel No, Type, Price) Booking (Hotel No, Guest No, Date From, Date_To, Room No) Guest (Guest_No, Name, City) Write RA queries for the following: a) Get the details (names and price) of all hotels in California. b) Get the average price of a room grouped by city. c) Find the hotel name and city of the hotel with the highest priced room. d) Get the hotel names and room numbers of any hotel rooms that have not been booked.

Define the term referential integrity constraint. Give an example of a referential integrity constraint for the tables you created for question 1.8.

In the Testa EV database design described in the previous question, please complete a field specifications form for the field 'Model_Cost' of the table 'Model_T'. The field records the cost of producing a specific EV model. Because its data come from the cost data of specific parts used to build the model, its value can be entered later and editing is allowed (null is allowed). The field value is required. Only decimal numeric data are supported for the entered value. The field can store a maximum of 10 digits (including 2 decimal places). The user of the database (data analyst) is responsible for entering and maintaining the data. No specific range of values is specified for this field. You should enter 'N/A' (or leave it unchecked) for elements that are not applicable.

Explain the role of functional dependencies and candidate keys in normalization.

Determine the functional dependencies that exist in the following table. After determining the functional dependencies, convert this table to an equivalent collection of tables that are in third normal form. ITEM(ITEM_ID, DESCRIPTION, ON_HAND, CATEGORY, LOCAITON, PRICE,(INVOICE_NUM, INVOICE_DATE, CUST_ID, FIRST_NAME, LAST_NAME, QUANTITY, QUOTED_PRICE))
