Description: 大型网站架构演变和知识体系
之前也有一些介绍大型网站架构演变的文章，例如LiveJournal的、ebay的，都是非常值得参考的，不过感觉他们讲的更多的是每次演变的结果，而没有很详细的讲为什么需要做这样的演变，再加上近来感觉有不少朋友都很难明白为什么一个网站需要那么复杂的技术，于是有了写这篇文章的想法，在这篇文章中将阐述一个普通的网站发展成大型网站过程中的一种较为典型的架构演变历程和所需掌握的知识体系，希望能给想从事互联网行业的朋友理清楚核心概念。 -The evolution and structure of large sites also have some prior knowledge describes the evolution of large-scale structure of the article sites, such as LiveJournal' s, ebay, and are very valuable reference, but feel they are talking about is more the result of time evolution, but not very Why do I need to do in detail about the evolution of this, plus a lot of friends have recently felt it hard to understand why a website needs less complex technology, so have the idea of writing this article, will be described in this article a sites ordinary course of large sites into a more typical course of evolution of the structure and the required knowledge system, hoping to give to friends in the Internet industry management core concepts clearly.

Description: 在JAVA 和 C# 中都有垃圾回收功能，程序员在分配一段内存后可以不再理会，而由垃圾回收自动回收，从而使程序员从复杂的内存管理中解脱出来。这是JAVA 和 C#的一大优点。而C++程序员在用 new 分配了一段内存后，还必须用 delete 释放，否则将造成资源泄漏。因此，一些C++ 书上经常告诫程序员：要养成好的习惯，new 与 delete 要成对出现，时刻记住将内存释放回系统。但是，事情只是这么简单吗？-In both JAVA and C#, garbage collection, in the allocation of a memory, the programmer can no longer ignore, and by recycling garbage collection automatically, so programmers from the complexity of memory management in earnest. JAVA and C# This is a big advantage. The C++ programmers with a new allocation of some memory, but also must delete the release, otherwise it will result in resource leaks. Therefore, some books on C++ programmers often warned: To develop good habits, new and delete to be in pairs, always remember that the memory is released back into the system. However, it is just that simple? Platform: |

Description: SQL Server client tools have very good functionality for creating database object scripts, but they don t always provide enough functionality to generate scripts the way programmers would like. These customized scripts could be used for database documentation. For that reason, database administrators and developers must code custom script generators. These generators usually generate scripts into text files that could be stored and versioned in a source control system. The custom generators could be created by using SMO objects. Scripting in SMO is controlled by the Scripter object and its child objects. A script is generated with the specified list and scripting options. The result is returned as a StringCollection system object.
To get started with SMO, first you must add a reference to Visual Studio. In the Add Reference window, select:
Microsoft.SqlServer.Smo
Microsoft.SqlServer.SmoExtended
Microsoft.SqlServer.Management.Sdk.Sfc

enormous, reaching billions level. For example, the number of pictures currently stored in
Facebook [4] is more than 140 billion, and both the number of users and daily access are
over one billion. Such massive files and accesses may result in that the expandability and
high performance will be the bottleneck of the efficient application of cloud computing,
