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.

- Database Management Jill Bill Marketplace is a business located in Florida. 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. The small vendors will report to the category managers on the nature of their stock and if and when restocking is required. All category managers report to the third…arrow_forwardSportTech Events.

The company would also like to have a list of potential sponsors that includes each sponsor’s contact information, such as the name, phone number, and address. Each event will have a single sponsor, but a particular sponsor may sponsor more than one event. Each location will need an ID, a contact person, and a phone number. A particular event will use only one location, but a location may be used for multiple events.

- 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.
