Database Systems please help me answer this question I will give you a good rating Thank you! Question 1: True or FalseQuestionAnswerThe external merge sort algorithm can be complete with as little as twobuffer pages.We should avoid RR, WR, RW and WW conflicts in the schedule.To have better performance, we should increase the number of I/O..Nested queries are costly, we should avoid them.Boyce-Codd Normal Form is the standard that every relation must satisfyBCNF.A relation must have at least one functional dependency.In a relational schema, one attribute can determine the type when insertingthe data.The log files only exist on the disk.

Merge sort is a out place algorithm, it may require huge buffer for performing completely, so that…

Suppose you need to sort relation r using sort—merge and merge—join the result with an already sorted relation s.The same idea is applicable even if both inputs to the merge join are the outputs of sort—merge operations. However, the available memory has to be shared between the two merge operations (the merge—join algorithm itself needs very little memory). What is the effect of having to share memory on the cost of each sort-merge operation?
1 Consider the sequence {a} = 1, 1 1 1 (a) Write the sequence using a recurrence relation. (b) Use summation notation to write an expression for the sum of the first n elements of the sequence.
The following two relations R and S have one attribute storing integers. Assume that a join is performed on this attribute. R = { 4, 3, 1, 6, 2, 9, 0, 5, 8, 7 } S = { 3, 4, 5, 8, 0, 2, 1, 6, 7, 9} Show the order of tuples output for the following join algorithms: (for example Sort Join would give (0,0), (1,1),...,(9,9) ) 1.One pass join where M=12 and R is put in memory: 2.Merge-sort-join with M=5: 3.Hash Join with three buckets and M=4. Assume R is the build relation and S is the probe relation. Also assume bucket 0 is output first. Output:
Give pseudocode for computing a join: r ⋈r.A=s.A s using a single MapReduce step, assuming that the map() function is invoked on each tuple of r and s. Assume that the map() function can find the name of the relation using context.relname().
Problem 2: relevant join älgorithms (Blocked-nested loop, index-nested loop, sort-merge, hash-based) based on increasing values for B. Hence, for small B, which would you choose? As B grows, which algorithm then becomes your choice, and what is the corresponding threshold value for B? Order all four algorithms and provide the three threshold values. Assume that the two relations R and S have sizes M and N respectively. W.l.o.g. assume M > N, and that the join attribute is a key value in S and a foreign key in R. Assume any index you might need exists, and provide any assumptions you are making. w, As B (number of buffer frames) grows, one's join algorithm choice can change: Order the four
For each of the following pairs of expressions, give instances of relations thatshow the expressions are not equivalent. (r ⟖s)⟖t and r ⟖(s⟖ t) In other words, the natural right outer join is not associative.
