Your university runs many hundreds of courses each semester and needs to keep track of key information on each one. 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. Initially, the values of the first seven items are known–the last three aren't. Design and implement an abstract data type that can be used to model this university course entity.

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.

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.
