join can be expressed as a theta join followed by elimination of repeated attributes by a projection The only change required is an extra step of deleting repeated attributes from the tuple tr ts , before adding it to the result The nested-loop join algorithm is expensive, since it examines every pair of tuples in the two relations Consider the cost of the nested-loop join algorithm The number of pairs of tuples to be considered is nr ns , where nr denotes the number of tuples in r, and ns denotes the number of tuples in s For each record in r, we have to perform a complete scan on s In the worst case, the buffer can hold only one block of each relation, and a total of nr bs + br block accesses would be required, where br and bs denote the number of blocks containing tuples of r and s respectively In the best case, there is enough space for both relations to t simultaneously in memory, so each block would have to be read only once; hence, only br + bs block accesses would be required If one of the relations ts entirely in main memory, it is bene cial to use that relation as the inner relation, since the inner relation would then be read only once Therefore, if s is small enough to t in main memory, our strategy requires only a total br + bs accesses the same cost as that for the case where both relations t in memory Now consider the natural join of depositor and customer Assume for now that we have no indices whatsoever on either relation, and that we are not willing to create any index We can use the nested loops to compute the join; assume that depositor is the outer relation and customer is the inner relation in the join We will have to examine 5000 10000 = 50 106 pairs of tuples In the worst case, the number of block accesses is 5000 400 + 100 = 2,000,100 In the best-case scenario, however, we can read both relations only once, and perform the computation This computation requires at most 100 + 400 = 500 block accesses a signi cant improvement over the worst-case scenario If we had used customer as the relation for the outer loop and depositor for the inner loop, the worst-case cost of our nal strategy would have been lower: 10000 100 + 400 = 1,000,400. rdlc code 39 Code 39 Client Report RDLC Generator | Using free sample for ...

In the following guide we'll create a local report (RDLC file) which features barcoding ..... ByteScout BarCode Generator SDK – C# – Code 39 Barcode. is paired with every tuple in the other block, to generate all pairs of tuples As before, all pairs of tuples that satisfy the join condition are added to the result The primary difference in cost between the block nested-loop join and the basic nested-loop join is that, in the worst case, each block in the inner relation s is read only once for each block in the outer relation, instead of once for each tuple in the outer relation Thus, in the worst case, there will be a total of br bs + br block accesses, where br and bs denote the number of blocks containing records of r and s respectively Clearly, it is more ef cient to use the smaller relation as the outer relation, in case neither of the relations ts in memory In the best case, there will be br + bs block accesses Now return to our example of computing depositor 1 customer, using the block nested-loop join algorithm In the worst case we have to read each block of customer once for each block of depositor Thus, in the worst case, a total of 100 400 + 100 = 40, 100 block accesses are required This cost is a signi cant improvement over the 5000 400 + 100 = 2, 000, 100 block accesses needed in the worst case for the basic nested-loop join The number of block accesses in the best case remains the same namely, 100 + 400 = 500 The performance of the nested-loop and block nested-loop procedures can be further improved: If the join attributes in a natural join or an equi-join form a key on the inner relation, then for each outer relation tuple the inner loop can terminate as soon as the rst match is found In the block nested-loop algorithm, instead of using disk blocks as the blocking unit for the outer relation, we can use the biggest size that can t in memory, while leaving enough space for the buffers of the inner relation and the output In other words, if memory has M blocks, we read in M 2 blocks of the outer relation at a time, and when we read each block of the inner relation we join it with all the M 2 blocks of the outer relation This change reduces the number of scans of the inner relation from br to br /(M 2) , where br is the number of blocks of the outer relation The total cost is then br /(M 2) bs + br.
