Develop an EER model for the following situation using the traditional EER notation, the
Visio notation, or the subtypes inside supertypes notation, as specified by your instructor:
An international school of technology has hired you to create a database management system to
assist in scheduling classes. After several interviews with the president, you have come up with
the following list of entities, attributes, and initial business rules:
• Room is identified by Building ID and Room No and also has a Capacity. A room can be
either a lab or a classroom. If it is a classroom, it has an additional attribute called Board
Type.
• Media is identified by MType ID and has attributes of Media Type and Type Description.
Note: Here we are tracking type of media (such as a VCR, projector, etc.), not the
individual piece of equipment. Tracking of equipment is outside the scope of this project.
• Computer is identified by CType ID and has attributes Computer Type, Type Description,…

Part I - Modeling You are building a database for a comic book store customer management system. Given the database specification below, your job is to turn the specification into an ER diagram. Your notation must be consistent with the notation used in our lecture notes. You can use all constructs and notations discussed in our lecture notes and nothing else (i.e.. oven notations used in the textbooks but not in our lectures cannot be used). Your ER diagram should capture all the information and constraints in the specification but, at the same time, be minimal. It means that redundant entities, relationships, attributes and constraints should be avoided. You may use any drawing tool of your choice (for example, Dia, diagrams.net, Lucidchart, etc.) to draw your ER diagram. Hand drawings will not be accepted. Database Specification The database keeps information about comic books, customers, orders, inventory and reviews. First, the database should…

You are required to design a database for a car championship. The requirements are as follows: In the championship, each car’s information such as the car model, the top speed and the acceleration will be stored, and it is identifiable through a unique car ID. Each car will be drove by only one driver. Each driver’s info such as the unique driver number, driver name and the experience level of the driver are stored as well. A driver may have many trainers from more experience drivers and these experience drivers would have at least one trainee who follow them.

Normalization is an important concept for database professionals.

- Consider the following business rule:An employee can manage multiple customers. A customer can be managed by multiple employees. How does this business rule(s) affect the database design? a.) The business rules define that there isn't a need for a relationship between the EMPLOYEE and CUSTOMER entities, as the relationship isn't a strong one. b.) The business rules define that there is a relationship between EMPLOYEE and CUSTOMER, and a 1:M relationship between those two entities. c.) The business rules define that there is a relationship between EMPLOYEE and CUSTOMER, and an M:N relationship between those two entities requiring a bridge table. d.) The business rules define that there is a relationship between EMPLOYEE and CUSTOMER, and a 1:1 relationship between those two entities.arrow_forwardHow is the Third Normal Form (3NF) achieved, and why is it important in database design?arrow_forwardThe following exercises are based on the BITS database user views as designed in Your Turn 6-1 in this chapter.
