Exercise: 2

Professors have a PROFID, a name, an age, a rank, and a research specialty. Projects have a project

number, a sponsor name (e.g. UGC/AICTE/...), a starting date, an ending date, and a budget. Graduate

students have an USN, a name, an age, and a degree program (e.g. MCA/ MPhil/BE/ME ..). Each

project is managed exactly by one professor (known as the project's principal investigator). Each project

is worked on by one or more professors (known as the project's co-investigators). Professors can

manage/work on multiple projects. Each project is worked on by one or more graduate students (known

as the project's research assistants). Graduate students can work on multiple projects. Each professor can

supervise many students. A student who is working on a project can be supervised by only one

professor.

Queries

a) Retrieve the names of all professors who do not have an ongoing project of more than 1

lakh.

b) Retrieve the names of all graduate students along with their professors under whom they
