由于简单模式匹配算法在一次字符比较失败后,简单的把模式串位置向前移动一个字符位置,这样就丢掉了前面字符匹配中得到的信息,效率差。所以就需要一种无回溯的算法来提高效率,这里使用KMP(Knuth-Morris-Pratt)算法。模式串前面的连续片断部分称“前缀模式”,前缀模式在模式串后部重复出现的情况可以用来避免重复进行已经做过的检查,这是KMP算法中的一个重要概念。-as simple pattern-matching algorithm to compare a character failure, a simple model put forward position Series mobile location of a character, would be lost in front of characters matching the information inefficiently. There is a need for a non-backtracking algorithms to improve efficiency, the use of KMP here (Knuth-Morris-Pratt) algorithm. Model Series in front of a row clips part said "prefix model," prefix string pattern in the pattern of recurring back can be used to avoid duplication of inspection has been done, KMP algorithm is an important concept.

本文一方面以实例的形式介绍产生数据封锁的各类情况,另一方面从数据库理论的角度加以分析,以期使读者既知其然,更知其所以然,使读者能够更加深入地理解Oracle的数据封锁机制,而不是简单地记住某些结论。-In this paper, on the one hand, to produce the form of examples of the types of data on the situation of the blockade, on the other hand, the theoretical point of view from the database to be analyzed in order to make the reader not only know-and know所以然, so that readers can be more in-depth understanding of Oracle data blockade mechanism, rather than simply to remember some of the conclusions.
