动态数据库
动态数据库外包正在成为“应用作为一种服务”旁边的一个重要的新趋势。在该模型中,数据所有权他们的数据给外部服务提供商。服务商做数据管理任务,并提供客户一个机制来处理外包数据库。由于服务提供商并不总是完全信任,安全和隐私的外包数据显著的问题。这些问题被称为数据的机密性,用户的隐私,数据隐私和查询的保证。其中,查询需要保证对数据库的外包模式的成功至关重要的作用。尽我们所知,然而,查询的保证,特别是对外包XML数据库,一直没有合理的任何以前的工作有关。我们提出了一个新颖的索引结构,结合B+树和梅克尔哈希树的优势,完全解决被称为正确性,在动态的外包XML数据库的完整性和新鲜度保证查询的三个问题。与真实数据的实验结果证明ourproposed解决方案的效率

求阶乘算法(0
求阶乘算法(0---10000)标准C++语言控制台应用程序 可能很多人都曾经想过要实现一些比较大的数的阶乘,但是C++中提供的标准数据类型其存储空间太小,根本无法实现。我们可以通过其他方法来实现,本程序用一个很简单的算法实现数的阶乘,程序很短,也很简单,各处都有注释,相信大家很容易就可以看懂,下载源码后在VC6.0中打开编译后即可运行,程序经少许改动可以实现更大的数的阶乘,有兴趣的读者在看完本程序后可一动手试试,其乐无穷!!希望这个程序能给大家一点帮助-The arithmetic for counting factorial(0-10000)
This is a standard C++ language console application, many people could want to relize the factorial of some large numbers, but the memory space of the standard data type provided by the C++ is too small, so it can not realize at all. But we can realize it by other method, the program realize the factorial of the number you give by a simple arithmetic ,this is a short and easy program, and there are remarks everywhere, I believe that everyone can easily understand it, after downloading the sound code you can open it in VC6.0, then edit and run it. you also can change something to realize the factorial of a larger number, the reader who is interesting in it can have a try, there are more happiness in it!! At last,
