Design a database suitable for a university registrar. This database should include information about students, departments, professors, courses, which students are enrolled in which courses, which professors are teaching which courses, student grades, TA's for a course (TA's are students), which courses a department offers, and any other information you deem appropriate. Note that this question is more free-form than the questions above, and you need to make some decisions about multiplicities of relationships, appropriate types, and even what information needs to be represented.

Hello there, see step by step explanation for answers

Explanation:

A database design for a University Registrar. The following requirements are for designing a Database Schema.

It should include:

1. Information about Students .

2. Information about Departments.

3. Information about Professors.

4. Information about courses.

5 . student Grades.

6. TA's for a course.

7. Department offering different courses.

For Designing Database for Registrar System We need to define various

1. Entity: Student, Course, Instructor, Course offering.

2. Attributes of Entities:

(a) Student entity has Sid, name, program as its attributes

(b)Course has Course_n, title, credits, and syllabus as its attributes

(d) course offering has section_no ,time, room, year ,semester as its attributes

3. Relationship among various entities

(a) enrolls

(b) teaches

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
