The Motor Vehicle Department Database
The Motor Vehicle Branch administers driving tests and issues driver's licenses.
Any person who wants a driver's license must take a learner's exam at any Motor
Vehicle Branch in the province.
If he/she fails the exam, he can take the exam again any time after a week of the
failed exam date, at any branch.
If he passes the exam, he is issued a license (type = learner's) with a unique
license number.
A learner's license may contain a single restriction on it. The person may take
his driver's exam at any branch any time before the learner's license expiry
date (which is usually set at six months after the license issue date).
If he passes the exam, the branch issues him a driver's license.
A driver's license must also record if the driver has completed driver's education, for
insurance purposes.

Within the JBM compound, you can purchase many types of products that are related to a specific category, for example, books or antiques. JBN does not own any of the stalls that sell products, rather they rent them out to small vendors. Each vendor has to pay a monthly fee to use the Marketplace. JBM products are available to different customers who sell their products daily. Each category type (e.g. books ) is managed by a particular supervisor. A customer will order their selected product in terms of the amount from that vendor, who is also free to apply discounts on any product in his store. Other than category supervisors there are other staff that manages different departments in the mall, but they all report to two marketplace managers.

- 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_forwardHi please help me with this database question thankyou so mucharrow_forwardSQL DML/DDL There are five tables describing employees of a company, departments, buildings, which department(s) an employee works in (and a percentage of the time for each), and in which building an employee works (an employee may have more than one office).
