A book is identified by its ISBN number, and it has a title, a price, and a date of publication. It is published by a publisher, which has its own ID number and a name. Each book has exactly one publisher, but one publisher typically publishes multiple books over time.
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.

- SQL A database used in an order-entry system is to contain information about customers, items, and orders. The following information is to be included. – For each customer: Customer number (unique) Valid “ship to” addresses (several per customer) Balance Credit limit Discount – For each order: Heading information: customer number, “ship-to” address, date of order. Detail lines (several per order), each giving item number, quantity ordered – For each item: Item number (unique) Warehouses Quantity on hand at each warehouse Item description For internal processing reasons, a “quantity outstanding” value is associated with each detail line of each order. [This value is initially set equal to the quantity of the item ordered and is progressively reduced to zero as partial shipments are made.] Design a database for this data.arrow_forwardAfter sending your resume to an employer, he/she asked you for references.

Among the data needed for each course would be the following: - University course identification number - Department course ID and section number (for multiple sections of the same course) - Number of credits for the course Days and times the course meets - Room in which the course meets (building ID and room number) Maximum course enrollment Campus on which the course is held - Name of the course instructor - Number of students currently enrolled and the student ID of each such student - Course status: open (for additional enrollment), closed, or canceled You must be able to change the value of each of these ten data items and, upon request, display all of this information.

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 firefighter number, a name, year of certification, home telephone number, and a rank (firefighter, fire lieutenant, fire captain, etc.) The state wants to record the fire department for which each firefighter currently works and each firefighter’s supervisor. Supervisors are always higher-ranking certified firefighters. Construct a relational database for New York’s fire departments and firefighters.arrow_forward
