Create a relational diagram for the database using crow’s foot notation. The ERD should include all the entities, relationships, and connectivity where applicable.
4 tables for the database: PATRON, BOOK_COPY, BOOK, and CHECKOUT. (Since a book may have multiple copies that may be purchased by the library at different time, it is better to have a BOOK_COPY table to avoid unnecessary data redundancy.) The data in the tables are as follows:
PATRON table records a patron’s ID, name, address, phone number, and email address.
BOOK table contains information such as author, title, publication date, subject, language, and a unique identifier (It can be the ISBN of the book) for each book.
BOOK_COPY table records a unique identifier for each copy of a book, the date of purchase, and the identifier of the book from the BOOK table.
CHECKOUT table records the date of check-out, patron’s ID, the identifier of the book copy…

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:…arrow_forward4-44. Figure 4-35 shows an EER diagram for Vacation Property Rentals. This organization rents preferred properties in several states. As shown in the figure, there are two basic types of properties: beach properties and mountain properties. Transform the EER diagram to a set of relations and develop a relational schema. Diagram the functional dependencies and determine the normal form for each relation. Convert all relations to third normal form, if necessary, and draw a revised relational schema. Suggest an integrity constraint that would ensure that no property is rented twice during the same time interval.arrow_forward
