Intermediate SQL Concepts

A query is a request for data or information from one or more database tables. This information could be presented in the form of pictorials, graphs, or complicated findings which helps in easy interpretation. Structured Query Language (SQL) is the most widely used programming language for retrieving and organizing data from relational databases. Collection of tables with rows and columns is referred to as a database. SQL is the language of databases. It makes it easier to extract specific data from databases, which can then be used for analysis.

Question

You are given the table raptors(g,0,s,h,a,w,k) with the indicated seven fields. You are also given the
functional dependency (FD)
g,5 -> h,a,w,k,o
(a) Give an FD that would violate 2NF.
(b) Give an FD that would violate 3NF.
(c) Give an FD that would violate BCNF.
(d) Assuming that these 4 FD's are the only ones, identify all candidate keys.

In three instances, the substitution of a surrogate key for the primary key of a connection has been described.
There is a lack of clarity on the connection between BQP and NP.
In three circumstances, the usage of a surrogate key for the primary key of a connection has been discussed.
Consider a transaction dataset where the possible items are P, Q, R, S, T, X, Y, and Z. Now consider the following 3-itemsets: {P, Q, R}, {P, Q, X}, {P, Q, T}, {P, T, X}, {P, T, Y}, {Y, Q, X}, {T, X, Y} If {Q, X} is infrequent, which of the above 3-itemsets must also be infrequent?

Our discussion of lossless decomposition implicitly assumed that attributes on the left-hand side of a functional dependency cannot take on null values. What could go wrong on decomposition, if this property is violated?
It is not obvious what the connection is between BQP and NP.
Consider the relation R, which has attributes that hold schedules of courses and sections at a university; R = {{Course_no, Sec_no, Offering_dept, Credit_hours, Course_level, Instructor_ssn, Semester, Year, Days_hours, Room_no, No_of_student}. Suppose that the following functional dependencies hold on R: {Course_no} -> {Offering_dept, Credit_hours, Course_level}{Course_no, Sec_no, Semester, Year} -> {Days_hours, Room_no, No_of_students, Instructor_ssn} {Room_no, Days_hours, Semester, Year} -> {Instructor_ssn, Course_no, Sec_no}Answer the following: What set of attributes form the key of R?
