3. Decomposition – 3NF. Consider relation R=(ABCDEFG), F={AB→AC, BC→AE, AD→BCE}. (a) Is it in 3NF? Provide a good justification – must use textbook definition and reasons given must be specific. (b) Apply the 3NF decomposition algorithm to decompose R into a set of 3NF tables. If this cannot be done, explain why.

Please answer part a, b,c,d
All parts of this question use the relation R = (ABCDEG) with the set of functional dependencies F = {A→BC, AD→G, C→D, G→C, BC→BDEG}. Use 3NF synthesis to find a 3NF decomposition of R that is both lossless-join and dependency-preserving. You must show all FDs that hold on each resulting relation. As a final step, minimize the number of relations in your decomposition, while still ensuring that each relation is in 3NF. 2.Give an example of a query that would run more slowly in your decomposition from above than in the original relation R. You must explain your answer.
Consider the relation schema Appointment={Patient, GP, Date, Time, Clinic, Room} and the followingset Σ of FDs:• Patient, Clinic, Date → Time• Patient → GP• GP → Clinic• Clinic, Date, Time, Room → Patient• Patient, Date, Time → Clinic, RoomIs the above relation schema Appointment in BCNF? If not, identify a BCNF decomposition for Appointment. You need to include the main steps used for identifying the BCNF decomposition. Check ifthis BCNF decomposition is dependency preserving
Consider a relational scheme R(A,B,C,D,E,H)R(A,B,C,D,E,H) and functional dependencies A→B,BC→D,E C,D AA B,BC→D,E C,D→A. Find all candidate keys of RR.
Suppose relations R(A,B) and S(B,C,D) are as follows
Let R(ABCDEFG) be a relation and F={A -> C, A-> D, B->F, E->F, F->G} a. Show example of lossless join decomposition of R into three tables R1, R2 and R3 and demonstrate that this decomposition is lossless using chase algorithm b. Find one key for this scheme and prove that it is a key using closure algorithm and definition of a key.
Q1Greetings, thatnk you in advance for your response. - Give a decomposition into 3NF of the following schema; - Prove that your 3NF normalization incurs no loss of functional dependencies r(A,B,C,D,E)F={ABàCDE, ACàD, BDàE} Thanks again.
