When using subtype associations, talk about the database table choices that are accessible.Decide the design you want to employ and talk about the relevant issues.
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…
3. 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 short-
hand representation and a diagram of your choice.
a.
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.
b.
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.
C.
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.
