how to graphically identify an entity, a the cardinality (o,N), a weak relation ship, and a strong relationship in a Crow's Foot ntation?
Distinguish between the ways in which functional dependencies may be utilized to express the following: • Between the entity sets student and teacher, there is a one-to-one relationship set that exists.• There is a many-to-one connection set between the entity setsstudent and teacher, which is defined as
You are given a relation R with the following attributes R(A,B,C,D,E). Assume that you were given the following functional dependencies: • FD1= AB -> E • FD2: = D -> C (a) What is a valid key for this relation? justify your response. (b) Is this relation in 3NF (Third Normal Form)? Justify your response. If it is not in 3NF, normalize the relation and demonstrate all steps of normalization.
We can convert any weak entity set to a strong entity set by simply adding appropriate attributes. Why, then,do we have weak entity sets? (a) We want to avoid the data duplication and consequent possible inconsis- tencies caused by duplicating the keyof the strong entity set.(b) Weak entities reflect the logical structure of an entity being dependent on another entity.(c) Weak entities can be deleted automatically when their strong entity is deleted.(d) All of the above.
Question 3Discuss in detailed explanation that the concept that an attribute that is part of a composite primary key is also a candidatekey.
Consider the unnormalized relation R with six attributes ABCDEF and the following functional dependencies:AB ->CDEB -> FC -> Da) What is the key(s) for the relation?b) What is the normal form of this relation? Explain it.c) Decompose R into 3NF relations step by step if it is not in 3NF.
Consider a relation with schema R(A,B,C,D,E,F,G). Choose the key for the relation for the following sets of functional dependencies. BCD→A BC→E A→F F→ G C→ D A→ G ? A) B B) C C) BC D) All combinations of attributes are key
Consider the relation r(A, B, C) with the attribute A as the index. Give an example of a query that can be answered only by looking at the index, rather than the tuples in the relationship. (Index-only plans are query plans that just utilise the index and do not access the actual relation.)
Question 1: Normalization Please TYPE IF POSSIBLE OR WRITE CLEARLY Consider a relation X with six attributes WYSMFE where WS is a composite primary key for X. Assume X has the following functional dependencies (X is one table with the attributes W, Y, S, M, F, E): WS è YMFE S è YME E è M In what normal form is relation X? Explain why? Is it possible to decompose X into a number of relations in order to achieve a higher normal form? Explain how (this means using English sentences and a diagram showing the final relation(s)).

Consider the following functional dependencies that hold on R(ABCDEF): AB-> CD, E -> C, B -> EF Is R in 3NF? Explain your answer in detail and decompose the relation, as necessary, into a collection of relations that are in 3NF. Make sure you first find all the key(s) of R so that you will be able to tell whether an attribute is prime.
