- Each publisher has a unique name; a mailing address and telephone number are also kept on eachpublisher. A publisher publishes one or more books; a book is published by exactly one publisher. Abook is identified by its ISBN, and other attributes are title, price, and number of pages. Each book iswritten by one or more authors; an author writes one or more books, potentially for differentpublishers. Each author is uniquely described by an author ID, and we know each author's name andaddress. Each author is paid a certain royalty rate on each book he or she authors, which potentiallyvaries for each book and for each author. An author receives a separate royalty check for each book heor she writes. Each check is identified by its check number, and we also keep track of the date andamount of each check.TasksDesign a SQL database using the above US superstore sales data set.1.Use Visual Paradigm to draw conceptual diagram2.Use Visual Paradigm todraw ERDarrow_forward3.

- The State of New York certifies firefighters through- out the state and must keep track of all of them, as well as of the state’s fire departments. Each fire department has a unique department number, a name that also identifies its locale (city, county, etc.), the year it was established, and its main telephone number. Each certified firefighter has a unique fire- fighter number, a name, year of certification, home telephone number, and a rank (firefighter, fire lieu- tenant, fire captain, etc.) The state wants to record the fire department for which each firefighter currently works and each firefighter’s supervisor. Supervi- sors are always higher-ranking certified firefighters. Construct a relational database for New York’s fire departments and firefighters.arrow_forwardPlease provide answer and explanation as wellarrow_forward1.
