This article provides an overview of recent developments in mainmemory database systems. With growing memory sizes and memory prices dropping by a factor of 10 every 5 years, data having a “primary home” in memory is now a reality. Main-memory databases eschew many of the traditional architectural pillars of relational database systems that optimized for disk-resident data. The result of these memory-optimized designs are systems that feature several innovative approaches to fundamental issues (e.g., concurrency control, query processing) that achieve orders of magnitude performance improvements over traditional designs. Our survey covers five main issues and architectural choices that need to be made when building a high performance main-memory optimized database: data organization and storage, indexing, concurrency control, durability and recovery techniques, and query processing and compilation. We focus our survey on four commercial and research systems: H-Store/VoltDB, Hekaton, HyPer, and SAP HANA. These systems are diverse in their design choices and form a representative sample of the state of the art in main-memory database systems. We also cover other commercial and academic systems, along with current and future research trends.

这套源码 适合毕业设计和课程设计,因为有足够的注释 ,所以理解简单。采用五层架构 ,符合高内聚,低耦合的设计规范。课程设计书里有 软件测试。 一.导入数据库 数据库文件一般在Data、DB或者App_Data文件夹内 有两种方法导入数据库,任选其一即可: 1.用sqlserver打开XXX.sql脚本,然后执行脚本,即可自动创建数据库。 2 用sqlserver附件mdf文件(此方法有版本限制,某些低版本sqlserver可能出现无法附件的情况)(推荐此方法) 二.运行项目 1.修改链接字符串 链接字符串在web.config文件内,一般使用默认配置即可无需修改, 修改也很简单,将你的数据库服务器名复制进来,替换掉链接字符串里的服务器名即可(就是这个点号)。操作请看图:。 2 用VS打开解决方案文件(即.sln文件),如果没有解决方案文件,就用VS打开网站,运行即可。如果运行起来后,没有自动显示页面,则需设置默认启动项,右键某个你想设置的.aspx文件,在弹出的界面中点击“设为启动项”即可,然后重新点击运行。
