如何下载和安装SQL Server数据库实验助手（DEA）

介绍 (Introduction)

The Database Experimentation Assistant (DEA) is a new Experimental solution provided by Microsoft used to help upgrading databases from older SQL Server versions (MSSQL 2005 or higher versions) to the more recent ones (MSSQL 2012 or higher versions). It accomplished this based in a given workload that is previously captured from the source database and later replayed on the target SQL Server instances for comparison.

数据库实验助手（DEA）是Microsoft提供的一种新的实验解决方案，用于帮助将数据库从旧SQL Server版本（MSSQL 2005或更高版本）升级到最新版本（MSSQL 2012或更高版本）。它基于给定的工作负载完成了此任务，该工作负载先前是从源数据库捕获的，后来又在目标SQL Server实例上重放以进行比较。

The tool offers the following capabilities for workload comparison analysis and reporting:

该工具提供以下功能用于工作负载比较分析和报告：

Automated script to set up workload capture and replay of production database (using existing SQL server functionality Distributed Replay & SQL tracing) 自动化脚本来设置生产数据库的工作负载捕获和重播（使用现有SQL Server功能分布式重播和SQL跟踪）
Perform statistical analysis model on traces collected using both old and new instances 对使用新旧实例收集的迹线执行统计分析模型
Visualize data through analysis report via rich user experience 通过丰富的用户体验通过分析报告可视化数据

The analysis metrics provided by the tool, for queries, compatibility errors and other workload comparison data will allow you to conduct experiments and performance tests across two SQL Server versions using production workloads providing you the necessary reports to give you an higher confidence to perform the upgrade by minimizing the risks.

该工具提供的用于查询，兼容性错误和其他工作负载比较数据的分析指标，将使您能够使用生产工作负载在两个SQL Server版本之间进行实验和性能测试，为您提供必要的报告，从而使您更有信心执行升级通过最小化风险。

NOTE: In the time I’m writing this article, DEA still in Technical-Preview release, meaning that things can slightly change in future releases but in general things should be kept as described in this article.

注意：在撰写本文时，DEA仍在技术预览版中，这意味着将来的发行版中情况可能会稍有变化，但通常应按照本文中的描述进行操作。

要求的组件 (Requested components)

After DEA has been installed you can click on the icon in the desktop area to start the application:

安装DEA之后，您可以单击桌面区域中的图标以启动应用程序：

Database Experimentation Assistant has three main features:

数据库实验助手具有三个主要功能：

For the Capture Workload and Replay Workload options there is no need for extra components but Analysis Reports has prerequisites that requires extra components to be installed in the same computer. When choosing this option without having one or more of those components installed a screen similar to the below one will be presented to you:

对于“ 捕获工作负载”和“ 重放工作负载”选项，不需要额外的组件，但是Analysis Reports具有先决条件，要求在同一台计算机上安装额外的组件。在未安装一个或多个组件的情况下选择此选项时，将显示类似于以下的屏幕：

NOTE: If your computer already has those components installed you won’t be able to see the above screen, meaning that you can immediately use the Analysis Reports option so no need to follow the below instructions.

注意：如果您的计算机已经安装了这些组件，则将无法看到以上屏幕，这意味着您可以立即使用“分析报告”选项，因此无需遵循以下说明。

For each of those necessary components there are, on the right side, direct links to download them.

对于每个必需的组件，在右侧都有直接链接下载它们。
