QUESTION 1 SQL: Consider the following database schema for flight reservation database.  A flight can be booked by many passengers, and a passenger can book different flights. For each booking, the date of the flight and price are recorded. The database schema is given below   Flight (FID:int, Airline:string(unique), DepartingAirport:string, ArrivalAirport:string, Rating: int (1,2,3,4,5) ) Booking (FlightID: int, PassengerCPR: int, Date: date, Time: time, Price: double) Passenger (CPR:int, FirstName: String, LastName: String, Address:String) Write SQL Code to:   Create the Flight Table.

“Martial Arts R Us” (MARU) needs a database. MARU is a martial arts school with hundreds of students. The database must keep track of all the classes that are offered, who is assigned to teach each class, and which students attend each class. Also, it is important to track the progress of each student as they advance.  Students are given a student number when they join the school. The number is stored along with their name, date of birth, and the date they joined the school. All instructors are also students, but clearly not all students are instructors. In addition to the normal student information, for all instructors, the date that they start working as an instructor must be recorded along with their instructor status (compensated or volunteer). An instructor may be assigned to teach any number of classes, but each class has one and only one assigned instructor. Some instructors, especially volunteer instructors, may not be assigned to any class. A class is offered for a…

Let's wa(k through a review of basic SQL syntax, using as an example the database that was mentionedearlier. This database has the following simple structure(* indicates a primary key):Courses: CourseID*, CourseName, TeacherIDTeachers: TeacherID*, TeacherNameStudents; StudentID*, StudentNameStudentCourses: CourseID*, StudentID*Using the above table, implement the following queries.Query 1: Student Enrollment Query 2: Teacher Class Size

Below is “Book Order,” the only table in library management system’s database. The design of “Book Order” as you may tell is in the zero normal formal form, you as the database designer want to convert the design into the third normal form.   Order ID Special order date Customer ID Customer last name Customer First name Customer birth date Book ISBN1 Book Title 1 Book Author 1 Book publication year 1 Book ISBN2 Book Title 2 Book Author 2 Book publication year 2 Store ID Store name Store location Special order status     Book Order(Order ID, Special order date, Customer ID, Customer last name, Customer First name, Customer birth date, Book ISBN1, Book Title 1, Book Author 1, Book publication year 1, Book ISBN2, Book Title 2, Book Author 2, Book publication year 2, Store ID, Store name, Store location, Special order status)

Problem: design a er diagram for a database to keep track of building inspections required by a department of Damaged Buildings (DB). DB  building inspections are requested by builders every month. Each building inspection is either passed or not. Inspections have a type code (3 characters, e.g. PLU, FRM, ELE, etc.) and possibly sequencing requirements. Some inspections cannot be performed before other inspections, e.g. final plumbing inspection cannot be performed until the framing inspection is passed. Each inspection has a numeric score, with 75 or more out of 100 being sufficient for a pass status. Each inspection data contains the date of inspection, inspector identification, inspection score, and textual information about the inspection. The textual information can be updated later, but the score can never be changed. FODB maintains a pool of inspectors. Each inspector has a unique 5 digit employee ID, name, and date they were hired. They can conduct any type of inspection but…

Given the business rule "An employee may have many degrees." Suppose that an employee has the following degrees. BA, BS, MBA, etc. These degrees could be stored in a single string as a multivalued attribute name EMP_DEGREE in an EMPLOYEE table such as the one shown below: EMP_NUM EMP_LNAME EMP_DEGREE 123 Carter BA, BS, MBA 124 Smith BBA, MBA 125 Jones AS 126 Doe BS, MS, PhD. This design is flawed, so correct it by creating additional table(s) and attributes(s) and show the relationships between them. Show all the data above in your table(s). Add additional data if new attributes were added. Show primary and foreign keys in your table(s).

CSC 472 Introduction to Database Systems Project Consider the contents of output tuples generated by a join operator. The advantage of "late materialization" approach is that future operators in the query plan never need to go back to the base tables to get more data. Group of answer choices True False
