求解网络中的最短路径。假设某个计算机网络有n个站点，依次编号为1,2,…,n；有的站点之间有直接的线路连接（即这两个站点之间没有其它站点），有的站点之间没有直接的线路连接。如果用三元组（i,j,f）来表示该网络中的站点I和站点j之间有直接的线路连接且它们之间的距离为f 当已知该网络各站点之间的直接连接情况由m个三元组（i1,j1,f1）,(i2,j2,f2),…,(im,jm,fm)确定时，要求计算出对于网络中任意一个站点g(1≤g≤n)到其余各站点的最短距离。-the shortest path. Assuming a computer network n site, followed by No. 1, 2, ..., n; Some sites have direct connections (that is, between two sites are no other site), and some sites have no direct connections. If three yuan (i, j, f) to the network said the site j site and I have direct connections between them but the distance of f the network known as the site of the direct link between the situation by 3 m (i1, j1, f1), ( i2, j2, f2), ..., (im, jm, fm) to determine, calculate requirements for a network site arbitrary g (1 g n) of the rest of the site is the shortest distance.

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.
