You need to fill the remaining five (5) entries in the below-given table with the Reference label of the correct relational database against each Sr. No. of the required information table.

A software developer has built a relational database model for the Learning Management System
of an online learning website. Various relations (tables) are defined to store data records related to
each entity in a separate relation. Three of the Relations (STUDENT, COURSE, and
ENROLLMENT) defined in that database model along with their attributes are given below:

data-ad-layout="in-article"
data-ad-format="fluid"
data-ad-client="ca-pub-7200085558568021"
data-ad-slot="3193586076">

	STUDENT
StudentID	StudentName	DegreeProgram	ResidentCity
…	…	…	…
…	…	…	…
…	…	…	…

 

		COURSE
CourseCode	CourseTitle	TeacherID	DegreeProgram	CreditHours
…	…	…	…	…
…	…	…	…	…
…	…	…	…	…

 

	ENROLLMENT
StudentID	CourseID	Semester
…	…	…
…	…	…
…	…	…

 

The developer needs to extract the following information given in Table-1 from his defined
database model using the relational database queries that consist of SELECT, PROJECT and JOIN
operators.

Table-1: Required Information

Sr. No.	Information required to be Extracted
1	Extract all the students from the STUDENT table belonging to a specific city.
2	Extract all the students from the STUDENT table who are enrolled in “BSCS” degree program.
3	Extract all the records in the columns “Student Name” and “Degree Program” of the STUDENT table.
4	Extract all the records in the columns “Course Code”, “Course Title” and “Degree Program” of the COURSE table.
5	Extract all the courses from the COURSE table having three or more credit hours.
6	Join STUDENT and COURSE tables using the Degree Program attribute.

Now, in the below given table (Table-2), some relational database operations (Queries) related to
the above database model are defined along with the name of resulting new relation. The name of
the resulting new relation is also used as reference to identify that query (i.e. each query is
referenced as A, B, C, D, E, F, G, H, I, J, K, and L).

Table-2: Relational Queries

Relational Query (Operation)	Name of the Resulting Relation (also a Reference Label)
A <- SELECT from STUDENT where ResidentCity='Lahore'	A
B <- PROJECT from STUDENT where City='Lahore'	B
C <- PROJECT [CreditHourse>=3] from COURSE	C
D    <-    JOIN    STUDENT    and      COURSE where       STUDENT. DegreeProgram=COURSE.DegreeProgram	D
E <- PROJECT CourseCode, CourseTitle, DegreeProgram from COURSE	E
F <- SELECT from STUDENT where DegreeProgram = 'BSCS'	F
G <- JOIN COURSE and STUDENT on Column.DegreeProgram	G
H <- PROJECT from COURSE Columns[CourseCode, CourseTitle, CreditHours]	H
I <- PROJECT StudentName, DegreeProgram from STUDENT	I
J <- SELECT Columns[StudentName, DegreeProgram] from STUDENT	J
K <- SELECT [DegreeProgram = 'BSCS'] from STUDENT	K
L <- SELECT from COURSE where CreditHours >=3	L

 This table (Table-2) contains both syntactically correct and incorrect relational database queries
(referenced as A to N). Out of these twelve (12) queries, six (6) syntactically correct queries can
be used to extract the information required in the table-1. 

You are required to identify the correct relational database query from Table-2: Relational
Queries for each of the “Required Information” entries in Table-1 and mention its reference label
in the 2nd column of the below-given table against the Sr. no. of Required Information. For
example, the answer to the “Sr. no. 1” entry of the “Required Information” column is query “A”
which is solved in the below-given table. 

Now, you need to fill the remaining five (5) entries in the below-given table with the Reference
label of the correct relational database against each Sr. No. of the required information table.

(Provide
your Answer only in the below-given Table)

 

Sr. No. of Required Information given in Table-1	Reference label of the Correct Relational Query  {Out of A, B, C, D, E, F, G, H, I, J, K, L} from Table-2
1	A
2	K
3	I
4	E
