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 from the BOOK_COPY table, and the due date.

Database Foundations: Design a database to produce the following reports. Do not use any surrogate keys in your design. For each guide, list the guide number, guide last name, guide first name, address, city, state, postal code, telephone number, and date hired. For each trip, list the trip ID number, the trip name, the location from which the trip starts, the state in which the trip originates, the trip distance, the maximum group size, the type of trip (hiking, biking, or paddling), the season in which the trip occurs, and the guide number, first name, and last name of each guide. A guide may lead many trips and a trip may be led by many different guides. For each client, list the client number, client last name, client first name, address, city, state, postal code, and telephone number

The database should contain the following six tables: Artists (artist_id: char(30), artist_name: char(30), artist_pop: int(5))Tracks (track_id: char(30), track_name: char(30), duration: int(10), tempo:real) Record (artist_id: char(30), track_id: char(30))Users (user_id: char(30), user_name: char(30), age: int(5), nationality: char(30), num_track_listened: int(10))Listen (user_id: char(30), track_id: char(30))Follow (user_id: char(30), artist_id: char(30), follow_date: datetime) Write a single SQL query for each request below. Find the ids of those users who have listened to at least one track but have not followed any artists. Find the ids and names of those users who have listened to some tracks recorded by the artist named 'Adele'. Find the ids and names of those users who have not listened to any track recorded by the artist named 'Adele'. Use ''NOT EXISTS'' to answer this query.
Alternate keys: Identify at least five keys (not already listed as PK or FK) needed by end users. These indexes would be considered Alternate or Secondary keys and are mostly used for queries and quick reporting. They may contain multiple columns.
