An E-learning website needs your help to design its database. They need to store information about teachers and online tutorials. Each teacher has a unique ID, name, and at least one field of specialty. Teachers form groups to prepare online tutorials. Each group has unique name and at least one teacher as a member. Each online tutorial has a title, date and organized by exactly one group. The title of the tutorial is unique for the group. Each tutorial consists of several sessions, described by their titles and durations. Naturally, each session is presented by one teacher and belongs to exactly one tutorial. In addition, sessions on the same tutorial have different titles.
Design an ERD for this application. Note any unspecified requirements, and make appropriate assumptions to make the specification complete.
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:…

The customer can reserve a table before arrival. Each reservation has a unique key and includes the date and time of reservation and the number of seats. Upon arrival, the customer places an order. Each order has a unique order number and includes one or more food items. Each food item is distinguished by an id and has name and price. We also keep track of the cashier who settle the payment with the customer before he leaves the restaurant. The cashier has an id and name.arrow_forwardYou 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.arrow_forward
- pls help me : Draw an ER diagram according to the following requirements:Database to manage daily medical examination and treatment in the hospital (not interested in treating inpatients):- The hospital has many doctors and nurses from different departments. Each doctor and nurse belongs to only one department- The patient when he comes to the doctor will be created a patient record if it is the first visit- Each visit will be made a medical record and assigned an initial clinic. Each visit is attended by a doctor and an assistant nurse.- The doctor may ask the patient to perform tests, x-rays, endoscopy, ....- After the results are available, the patient returns to the original clinic for the doctor to read the results and prescribe medicine if any- Patients can buy medicine in the hospital pharmacy or buy it outsidearrow_forwardProblem 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…arrow_forwardInstructions: Create a dimensional model for a particular business process involving gym membership. A customer can sign up for a membership of say one, three, six or twelve months.

On a particular day, the active members are those with a start date before the day and an end date after that day.
