Create a data model design
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:…
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.
