- INDICATE THE CHANGES(USING SHORTHAND REPRESENTATION) YOU WOULD NEED TO MAKE TO THE ORIGINAL KIMTAY PET SUPPLIES DATABASE DESIGN TO SUPPORT THE FOLLOWING REQUIREMENTS. A CUSTOMER IS NOT NESSESARILY REPRESENTED BY A SINGLE SALES REP, BUT THEY CAN BE REPRESENTED BY SEVERAL SALES REPS. WHEN A CUSTOMER PLACES AN ORDER THE SALES REP WHO GETS THE COMMISSION ON THE INVOICE MUST BE IN THE COLLECTION OF SALES REPS WHO REPRESENT THE CUSTOMERIndicate the changes (using the shorthand representation) that you would need to make to the original KimTay Pet Supplies database design in the event that the original Requirement 3 is changed as follows. For an item, store the item’s ID, description, category, and price. In addition, for each location in which the item is located, store the value of the location, the description of the location, and the number of units of the item stored in the location. Draw an E-R diagram for the new design.Indicate the changes (using the shorthand representation) that you would need to make to the original KimTay Pet Supplies database design to support the following requirements. There is no relationship between customers and sales reps. When a customer places an order, any sales rep can process the order and create the invoice. On the invoice, you need to identify both the customer placing the order and the sales rep responsible for the invoice. Draw an E-R diagram for the new design.
- Design a survey form of your own. Fill it out as it might have been completed during the database design for Henry Books. For any questions you have too little information to answer, make a reasonable guess. (Ray Henry, the owner of a bookstore chain named Henry Books, gathers and organizes information about branches, publishers, authors, and books. Each local branch of the bookstore has a number that uniquely identifies the branch. In addition, Ray tracks the branch’s name, location, and number of employees. Each publisher has a code that uniquely identifies the publisher. In addition, Ray tracks the publisher’s name and city. The only user of the Book database is Ray, but you do not want to treat the entire project as a single user view. Ray has provided you with all the reports the system must produce, and you will treat each report as a user view. Ray has given you the following requirements: User View 1 Requirements: For each publisher, list the publisher code, publisher name, and…indicate the changes(using the shorthand representation)that you would need to make to the original kimtay pet supplies database design to support the following requierements.there is no relationship beetween customers and seles reps.when a customer places an order. any sale rep can process the order and creat the invoice.on the invoice you need to identify both the customer placing the order and the sales rep responsible for the invoice. draw an e-r diagram for the new design.Subject: Database Topic: EERD Please use UML Modelling Notation.

A car dealership wishes to maintain data about the customers who purchase a car. Each customer may purchase one or more vehicles and each vehicle can be purchased by many different customers over time (for example, a customer maypurchase a new vehicle, trade that vehicle in and someone else can purchase the vehicle traded in.) Data that the dealership wishes to keep regarding customers includes customer identification number, name, address, homephone, work phone, cell phone and e-mail address. Information about vehicle includes vehicle identification number, make, model, year, transmission type, engine size and color. Vehicles can be a member of one of the following categories: cars, trucks, minivans or SUVS. A vehicle can be amember of only one category at a…
- You are to design a Hospital database. So before creating the database, your task is to design the ER diagram based on the following data requirements: The hospital has departments. Each department has a name, department ID, location. Location consists of floor number and wing number (which will contain the values North, South, East or West). b. Doctors work for the department. Doctors have license number., name, title, multiple specializations. Some doctors supervise other doctors. c. A patient will have a name, unique ID. may have more than one phone number, age, height, weight and symptoms. d. Patients take appointments from doctors. Appointment date and time is recorded. e. A patient may have an attendant. An attendant will have his/her name and relationship with the patient as a record in the database. The hospital allows 1 attendant with each patient. Write down any assumptions you may have made.You will need to create the database tables and choose sensible data types for each column.Make sure to maintain entity and referential integrity, and implement all the above constraints.Since other developers work in parallel on other parts of the system, you will need to strictly follow the above specification to correctly implemented in your database. Otherwise, the other software will not be able to use your database. This means, one needs to be able to rely on all constraints being correct, the spelling of table and column names being as given, and that the data types that you chose will allow for sensible data to be added to the database in the future.For testing purposes, you are asked to insert the data specified below into the tables, but no other data except this.In short:1. You will need to create the tables as specified2. You will need to add the data specified Please use the 3.sql and implement your tables using the sketched CREATE TABLE commands. Add the necessary queries…Problem Statement: You are the CTO of a startup based out of Arlington, VA that needs to setup a database to keep track of the details of the customers: last name, first name, customer ID, street address, customer star rating (a rating on a 1– 5 scale, with 5 being best, representing the type of customer) and phone number. It also needs to keep track ofsimilar information for suppliers as well (although instead of supplier first and last name, there will just be a suppliercompany name). The database should maintain the data on products that are offered. Information about whichproduct is offered by which supplier should also be maintained. Finally, which customers have purchased whichproducts should also be tracked (note that we are only interested in which customers bought which product, but notconcerned about the date or how many were bought). 1.1 Business Rules: Assumptions for the business model are as follows:•Only customers that have purchased one or more products will exist in…
- 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.You are to design a Hospital database. So before creating the database, your task is to draw the ER diagram based on the following data collected and analyzed: A hospital will have a name, unique id, multiple helpline numbers (one for doctor's appointment, one for ambulance, one for bill information and one for other services' info) and locations. A hospital may have more than one location as it may have different branches and each of the locations will have a building no., street address, road no. and city name. A patient will have a name, unique ID, may have more than one phone number, age, height, weight and symptoms. A patient takes an appointment in a hospital and the appointment date is recorded. A patient may have an attendant. An attendant will have his/her name, contact numbers and relationship with the patient as a record in the database. Due to the covid situation, the hospital authorities will only allow 1 attendant with 1 patient.Normalization works through a series of stages called normal forms.
