Create an Entity-Relationship Model for the Queen Anne Curiosity Shop The first assignment for the class project is to create an entity-relationship model of the Queen Anne Curiosity Shop database. This assignment requires you to apply the knowledge gained from study of chapter 4 of the textbook. You will create the entity-relationship model using the ERDPlus database modeling tool. The Queen Anne Curiosity Shop database contains the following tables: CUSTOMER (CustomerID, LastName, FirstName, Address, City, State, ZIP, Phone, EmailAddress) EMPLOYEE (EmployeeID, LastName, FirstName, Phone, EmailAddress) VENDOR (VendorID, CompanyName, ContactLastName, ContactFirstName, Address, City, State, ZIP, Phone, Fax, EmailAddress) ITEM (ItemID, ItemDescription, PurchaseDate, ItemCost, ItemPrice, VendorID) SALE (SaleID, CustomerID, EmployeeID, SaleDate, SubTotal, Tax, Total) SALE_ITEM (SaleID, SaleItemID, ItemID, ItemPrice) Note that the above table descriptions follow the textbook convention:…

Implement a new independent entity phone in the Sakila database. Attributes and relationships are shown in the following diagram: The diagram uses Sakila naming conventions. Follow the Sakila conventions for your table and column names: All lower case Underscore separator between root and suffix Foreign keys have the same name as referenced primary key Write CREATE TABLE and ALTER TABLE statements that: Implement the entity as a new phone table. Implement the has relationships as foreign keys in the Sakila customer, staff, and store tables. Remove the existing phone column from the Sakila address table. Step 2 requires adding a foreign key constraint to an existing table. Ex: ALTER TABLE customer ADD FOREIGN KEY (phone_id) REFERENCES phone(phone_id) ON DELETE SET NULL ON UPDATE CASCADE; Specify data types as follows: phone_id, phone_number, and country_code have data type INT. phone_type has date type VARCHAR(12) and contains strings like 'Home', 'Mobile', and 'Other'. Apply…

Please follow this ER diagram, give a description, and make a schema diagram from it. Also, make database (constraint tables) & intent some sample data. Lastly, run some SQL functions code.   Please don't copy from anywhere. I need it for my project.

The database used for this question is a very simple one with the following schema: (Primary keys are bold, foreign keys are underlined)   CUSTOMER (CustID, FirstName, LastName, City, Phone, Email) INVOICE (InvoiceNumber, CustID, Date) INVOICE_ITEM(InvoiceNumber, ItemNumber, Quantity) ITEM (ItemNumber, ItemName, UnitPrice)   When a customer makes a purchase, an invoice is created. The invoice may be for many items. For example, in a single purchase, a customer might buy 10 Back Scratchers, 4 Hair Removers and a Dog Lead. Provide relational algebra (NOT SQL) queries to find the following information. Each question is worth 2 marks. NOTE: You can use the symbolss, P, etc., or the words’ PROJECT’, ‘RESTRICT’etc.as you prefer. You do not need to try to make efficient queries – just correct ones. Where you use a join, always show the join condition.   List the first and last names of Customers who come from the City named Perth. List the first and last names of customers who had…

Given the database schema below, write a relational algebra expression to get the count of records in the DEPENDENT relation group by Essn. Also, show the result of your query.

A DreamHome database has following tables. Branch (branchNo, street, city, postcode) Staff (staffNo, fName, lName, position, sex, DOB, salary, branchNo) PropertyForRent (propertyNo, street, city, postcode, type, rooms, rent, ownerNo, staffNo, branchNo) PrivateOwner (ownerNo, fName, lName, address, telNo)   Which is the correct relational algebra to express the following query?       List the city and street of all branches which assistant staff’s salary is not greater than 9000 and age is at least 31. ( ) $$\Pi_{branchNo,street,city}(\sigma_{position='assistant' \wedge salary≤9000 \wedge DOB>'1-Jan-1990'} (Staff \bowtie Branch))$$ ( ) $$\sigma_{branchNo,street,city}(\Pi_{position=’assistant’ \wedge salary≤9000 \wedge DOB>’1-Jan-1990’}(Staff \cap Branch))$$ ( ) $$\sigma_{branchNo,street,city}(\sigma_{position=’assistant’ \wedge salary<9000 \wedge DOB>31}(Staff \bowtie Branch))$$ ( ) $$\Pi_{branchNo,street,city}(\sigma_{position=’assistant’ \wedge salary≤9000 \wedge…

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.

Generate the table creation DDL for the schema. Consider the keysprimary and foreign.
