External sort merge sort loser tree

the time of external memory read and write reduction, which leads to the use of the "loser Tree" of the loser. In the process of internal merging, the number of minimum records in K-merge segments is reduced to (rounding up) (log2k) times to the total number of comparisons (rounding up) (log2m) (n-1), regardless of K.The loser tree is a fully binary tree, so the data structure can take one-dimensional arrays. The number of its elements is k leaf node, k-1 A comparison node, 1 champions node tot

The unsafe factors of Oracle8 and some explanations

not easy to find but very fatal are often overlooked. Oracle8 also exist insecurity factors, many are trying to upgrade to Oracle8 as soon as possible Oracle7.1, Oracle7.2, Oracle7.3 users can not take into account this factor. Of course, this insecurity was not discovered in a flash, but when we managed to manage a very large table, this vulnerability might not or could not be found in a small or medium-sized database created with Oracle. Because the unique characteristics of Oracle8 have redu
