Transcribed Image Text: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: primary keys are underlined and
foreign keys are italicized.
The primary keys in these tables are:
CustomerID in CUSTOMER
EmployeelD in EMPLOYEE
VendorID in VENDOR
Itemid in ITEM
SalelD in SALE
SalelD, SaleltemID in SALE_ITEM (these two columns form a composite primary key)
Assume that CustomerID of CUSTOMER, EmployeelD of EMPLOYEE, VendorlD of VENDOR, ItemlD of
ITEM, and SalelD of SALE are all surrogate keys with values as follows:
Increment by 1
Increment by 1
CustomerlD
Start at 1
EmployeelD
Start at 1
VendorID
Start at 1
Increment by 1
Increment by 1
Increment by 1
ItemID
Start at 1
SalelD
Start at 1
The foreign keys in these tables are:
VendorID in ITEM
CustomerlD and EmployeelD in SALE
SalelD and ItemID in SALE_ITEM
