Repository data storageIn Subversion1.2, there are two ways to store data in the repository. One is to store data in a Berkeley DB database, and the other is to use a normal file, using a custom format. Because Subversion developers call the

  Abstract: Compared with common databases, embedded databases have the characteristics of small size, complete functions, portability, and robustness. This paper analyzes and compares typical embedded databases SQLite and Berkeley dB. First, the

Overview of embedded database used in embedded database Berkeley DB Overview Http://www.cppblog.com/michaelgao/archive/2008/06/24/54435.htmlBerkeley DB is a library of open source embedded databases (database library) developed by the US Sleepycat

This article is the second article in the series of "implementing key-Value Pair storage" Original article from Emmanuel goossaert (codecapsule.com) At the beginning of this article, I will explain the reasons for using an existing model instead

1. MongoDBIntroducedMongoDB is a database based on distributed file storage. Written by the C + + language. The main solution is the access efficiency of massive data, providing a scalable and high-performance data storage solution for Web

As a new generation of version control software, SVN (subversion) is developed on the basis of CVS. It fixes various drawbacks of CVs and is expected to become a substitute for open-source CVs. (1) Preparations You can download the latest version of

Berkeley DB is a long history of embedded database system, mainly used in Unix/linux operating system. The Berkeley DB Store is a Key/value key value pair that can be understood as a super hash table on a hard disk. It can manage 256TB of data and

In this article, I'll explain why I'm using an existing model in my project instead of starting completely from scratch. I'll list a series of criteria for choosing a K-V database model. Finally, it outlines and selects some of the K-V databases

1. Compile the installation with the source file. The total source files are two:subversion-1.6.1.tar.gz (Subversion source file)Subversion-deps-1.6.1.tar.gz (Subversion dependent file)Note that the file version must be consistent , otherwise it is

To install the SVN method in compile mode 1. Compile and install with source files. A total of two source files are: subversion-1.6.1.tar.gz (Subversion source file)Subversion-deps-1.6.1.tar.gz (Subversion dependent file) Note that the file

Next, I will introduce two methods for setting up svn and svn service configuration in Linux. One is to compile the source code to install svn, and the other is to install the svn service in the yum command mode, next we will introduce them

Method One:1, wget http://subversion.tigris.org/downloads/subversion-1.6.1.tar.gz2, wget http://subversion.tigris.org/downloads/subversion-deps-1.6.1.tar.gz[or directly upload to the Baidu cloud of these two files]3.Tar zxvf

SVN server has two ways to run: 1, independent server (for example: svn: // xxx.com/xxx); 2, with apache (for example: http://svn.xxx.com/xxx); in order not to rely on apache, I chose the first method: Independent svn server. The SVN storage version

Nothing can be done at work. Many places are speculation or inaccurate. 1) bdb compilation is performed under the build_windows and build_unix directories. VC directly converts the DSW of vc6 to vc9. Remember to set the compilation option to debug x8
