WHAT IS POWER BI

Power BI 是软件服务、应用和连接器（connectors)的集合，共同将您互不相关的数据源转化成coherent(一致耦合）、visually immersive(视觉沉浸）、有互动性的见解。

How Power BI matches your role

稍后我们将在 Guided Learning课程中，我们就Desktop service Mobile app这三个元素进行讨论。我们将在Power BI Desktop中制作报告，在service中分享，在mobile app上深入灌输

The Flow of Work in Power BI

The common flow of activity in Power BI is the following:
- Bring data
into Power BI Desktop, and create a report.
- Publish to the Power BI
service, where you create new visualizations or build dashboards
- Share your dashboards with others, especially people who are on the
go View and interact with shared dashboards and reports in Power BI
Mobile apps

Building Blocks of Power BI

PowerBI基本的6构件：

• Visualizations可视化：
  visuals（图像画面）,数据的视觉展现。形式多样：表、图、彩色地图等等
• Datasets数据集：
  数据的集合，PowerBI用以构造Visualizations.DateSet可以是一个简单的excel表格，也可以是不同数据源的组合。PowerBI有很多内置connectors可以连接到不同资源，并且可以按需过滤，形成你的dataset
• Reports报告
  report是来自DataSet的visualization（visuals）的集合，出现在一个或多个page上
• Dashbords仪表盘
  one page visuals,一个或几个page上visualization的集合
• Tiles
  report和dashbord上的单个visual单元。一个长方形框框内。

A FEW CLICKS TO CREATE DASHBORD

use a Content Pack – a ready-made collection of visuals and reports – and connected to a software service to populate the content pack and bring that data to life.
We also used natural language queries, called Q & A, to ask questions of our answers, and let Power BI create visuals based on those questions. Lastly, we set up a refresh schedule for our data, so we know when we go back to the Power BI service, that data will be fresh.

content pack : a collection of pre-configured(预先配置的）, ready-made（现成的） visuals（视觉图像） and reports based on specific data sources, such as Salesforce.
