Concepts in Designing Database
A database design is the process of data organization based on a database model. The process deals with identifying what data should be stored in a database and how data elements relate to each other.
Entity Relationship Diagram
Complex real-world applications call for large volumes of data. Therefore, it is necessary to build a great database to store data safely and coherently. The ER data model aids in the process of database design. It helps outline the structure of an organization’s database by understanding the real-world interactions of objects related to the data. For example, if a school is tasked to store student information, then analyzing the correlation between the students, subjects, and teachers would help identify how the data needs to be stored.

- Question 15 (₁ Solve for the rotation operator that is defined as an Euler Z,Y,X, thetaY, thetaP,thetaR rotation set (called a Yaw-Pitch-Roll or YPR rotation). Reduce your answer as much as possible. Please use exact syntax as follows: cos(thetaY) sin(thetaP) cos(thetaR) cos(thetaY) *cos(thetaP) cos(thetaY+thetaP) 0 1 etc. Do no insert any extra white spaces ALSO! When entering your answer, please order the trig terms in each expression in the order Yaw, then Pitch, then Roll: for example: cos(thetaY)*sin(thetaR) not sin(thetaR)* cos(thetaY) R(m,n) is row m, column n R(1,1) A/ A R(1,3) AR(2,1) AR(2,2) AR(2,3) AR(3,1) AR(3,2) AR(3,3) A/ R(1,2)CONVERSION FROM CFG TO CNF3.

After reflection, come up with your own answer to each of the questions. Scenario 1 Alexis, a gifted high school student, wants to become a doctor. Because she comes from a poor family, she will need a scholarship in order to attend college. Some of her classes require students to do extra research projects in order to get an A. Her high school has a few older PCs, but there are always long lines of students waiting to use them during the school day. After school, she usually works at a part-time job to help support her family. One evening Alexis visits the library of a private college a few miles from her family's apartment, and she finds plenty of unused PCs connected to the Internet. She surreptitiously looks over the shoulder of another student to learn a valid login/password combination. Alexis returns to the library several times a week, and by using its PCs and printers she…Given the following UML diagram: Student - studentID: String + getStudentID(): String + toString(): String Person - lastName: String - firstName: String - dateOfBirth: Date - address: Address + getName(): String + getDOB(): Date + getAddress(): Address + toString(): String Professor - employeeID: String + getEmployeID(): String + toString(): String Write an implementation for the class Professor. DO NOT include or implement any constructor for this class. There are no abstract methods/classes in this example. toString method will return any simple String that contains firstName and employeelD only; no less, no more!! Assume firstName was defined as protected in class Person. You are not allowed to add implementation for any class or methods other than what is listed in the question statement. 2
