Question: Consider a relation named as BOOK that contains data about the books in a library. BOOK relation was initially created with the attributes BookID (an id that library assigns), ISBN, CopyNr (used to differentiate copies of the same book), Title, PublYear, Author, and AuthorBornYear. Primary key: BookID, CopyNr and Author Candidate key: ISBN, CopyNr and Author Below you see dependencies of attributes: Dependency 1 (D1): ISBN, Title, PublYear, AuthorBornYear were dependent on BookID, CopyNr, and Author Dependency 2 (D2): Title and PublYear were dependent on BookID, CopyNr Dependency 3 (D3): AuthorBornYear was dependent on Author First determine which normal form (1NF, 2NF, 3NF, or BCNF) the above relation is, and why. Then, if necessary, convert the above relation to the highest normal form (BCNF). Write any assumptions that you make Subject: MYSQL
Consider the following relation for published books:BOOK (Book_title, Authorname, Book_type, Listprice, Author_affil, Publisher)Author_affil refers to the affiliation of the author. Suppose the following dependencies exist:Book_title → Publisher, Book_typeBook_type → ListpriceAuthor_name → Author-affil (a) What normal form is the relation in? Explain your answer.(b) Apply normalization until you cannot decompose the relations further. State the reasons behind eachdecomposition.

1. Consider the following relations:Student (snum: integer, sname: string, major: string, level: string, age: integer)Class (name: string, meets at: string, room: string, fid: integer)Enrolled (snum: integer, cname: string)Faculty (fid: integer, fname: string, deptid: integer)The meaning of these relations is straightforward; for example, Enrolled has onerecord per student-class pair such that the student is enrolled in the class. Level is atwo character code with 4 different values (example: Junior: A Level etc)Write the following queries in SQL. No duplicates should be printed in any of theanswers.i. Find the names of all Juniors (level = A Level) who are enrolled in a classtaught by Prof. Kwizeraii. ii. Find the names of all classes that either meet in room R128 or have five ormore Students enrolled.iii. Find the names of all students who are enrolled in two classes that meet atthe same time.
Create an unnormalized relation using student and class entities.
question one: defined the following relation on A={0,2,5,6} Answer each of the following questions by listing the index of the relation. For example, for Part 1), if R1 and R2 and are reflexive, simply enter 1, 2 as the answer.1) Which relations are reflexive? 2) R0={(0,6),(6,6),(6,2),(0,0),(0,2),(2,2),(5,5)} 3) R1={(6,6),(2,2),(5,5),(0,0),(0,6)} 4) R2={(0,6),(6,6),(0,0),(5,6),(6,5),(5,0),(5,5),(2,2),(0,5) 5) R3={(5,5),(0,0),(6,6),(2,2) 6) R4={(5,5),(6,2),(6,6),(0,0),(6,5),(2,6),(2,2)} 1) Which relations are reflexive? 2) Which relations are symmetric? 3) Which relations are anti-symmetric? 4) Which relations are transitive? 5) Which relations are equivalence relations? 6) Which relations are partial orders? question two :defined the following relation on A={0,1,5,6} Answer each of the following questions by listing the index of the relation.
