What is Power BI? 什么是 Power BI？

Power BI is a collection of software services, apps, and connectors that work together to turn your unrelated sources of data into coherent, visually immersive, and interactive insights. Your data might be an Excel spreadsheet, or a collection of cloud-based and on-premises hybrid data warehouses. Power BI lets you easily connect to your data sources, visualize and discover what's important, and share that with anyone or everyone you want.
Power BI 是软件服务、应用和连接器的集合，它们协同工作，将不相关的数据源转化为连贯的、视觉上沉浸式的交互式见解。您的数据可能是 Excel 电子表格，也可能是基于云的和本地混合数据仓库的集合。Power BI 使你能够轻松连接到数据源，可视化和发现重要内容，并与所需的任何人或每个人共享。

Power BI consists of several elements that all work together, starting with these three basics:
Power BI 由几个元素组成，它们都协同工作，从以下三个基本要素开始：

• A Windows desktop application called Power BI Desktop.
  名为 Power BI Desktop 的 Windows 桌面应用程序。
• An online software as a service (SaaS) service called the Power BI service.
  称为 Power BI 服务的在线软件即服务 （SaaS） 服务。
• Power BI Mobile apps for Windows, iOS, and Android devices.
  适用于 Windows、iOS 和 Android 设备的 Power BI 移动应用。

These three elements—Power BI Desktop, the service, and the mobile apps—are designed to let you create, share, and consume business insights in the way that serves you and your role most effectively.
这三个元素（Power BI Desktop、服务和移动应用）旨在让您以最有效地为您和您的角色服务的方式创建、共享和使用业务见解。

Beyond those three, Power BI also features two other elements:
除了这三个元素之外，Power BI 还具有两个其他元素：

• Power BI Report Builder, for creating paginated reports to share in the Power BI service. Read more about paginated reports later in this article.
  Power BI Report Builder，用于创建要在 Power BI 服务中共享的分页报表。在本文后面阅读有关分页报表的更多信息。
• Power BI Report Server, an on-premises report server where you can publish your Power BI reports, after creating them in Power BI Desktop. Read more about Power BI Report Server later in this article.
  Power BI 报表服务器，一个本地报表服务器，您可以在 Power BI Desktop 中创建 Power BI 报表后，在其中发布这些报表。本文稍后将阅读有关 Power BI 报表服务器的更多信息。

How you use Power BI depends on your role in a project or on a team. Other people, in other roles, might use Power BI differently.
使用 Power BI 的方式取决于您在项目或团队中的角色。其他角色的其他人可能会以不同的方式使用 Power BI。

For example, you might primarily use the Power BI service to view reports and dashboards. Your number-crunching, business-report-creating coworker might make extensive use of Power BI Desktop or Power BI Report Builder to create reports, then publish those reports to the Power BI service, where you view them. Another coworker, in sales, might mainly use the Power BI Mobile app to monitor progress on sales quotas, and to drill into new sales lead details.
例如，您可能主要使用 Power BI 服务来查看报表和仪表板。您负责数字运算、创建业务报表的同事可能会广泛使用 Power BI Desktop 或 Power BI Report Builder 来创建报表，然后将这些报表发布到 Power BI 服务，以便您查看它们。另一位销售同事可能主要使用 Power BI 移动应用来监控销售配额的进度，并深入了解新的销售线索详细信息。

If you're a developer, you might use Power BI APIs to push data into semantic models or to embed dashboards and reports into your own custom applications. Have an idea for a new visual? Build it yourself and share it with others.
如果您是开发人员，则可以使用 Power BI API 将数据推送到语义模型中，或将仪表板和报表嵌入到您自己的自定义应用程序中。有新视觉对象的想法？自己构建并与他人分享。

You also might use each element of Power BI at different times, depending on what you're trying to achieve or your role for a given project.
你也可能在不同时间使用 Power BI 的每个元素，具体取决于你要实现的目标或你在给定项目中的角色。

How you use Power BI can be based on which feature or service of Power BI is the best tool for your situation. For example, you can use Power BI Desktop to create reports for your own team about customer engagement statistics and you can view inventory and manufacturing progress in a real-time dashboard in the Power BI service. You can create a paginated report of mailable invoices, based on a Power BI semantic model. Each part of Power BI is available to you, which is why it's so flexible and compelling.
您如何使用 Power BI 可能取决于 Power BI 的哪个功能或服务最适合您的情况。例如，您可以使用 Power BI Desktop 为您自己的团队创建有关客户参与度统计数据的报告，并且可以在 Power BI 服务的实时仪表板中查看库存和制造进度。您可以基于 Power BI 语义模型创建可邮寄发票的分页报表。Power BI 的每个部分都可供你使用，这就是它如此灵活和引人注目的原因。

One common workflow in Power BI begins by connecting to data sources in Power BI Desktop and building a report. You then publish that report from Power BI Desktop to the Power BI service, and share it so business users in the Power BI service and on mobile devices can view and interact with the report.
Power BI 中的一个常见工作流首先连接到 Power BI Desktop 中的数据源并生成报表。然后，将该报表从 Power BI Desktop 发布到 Power BI 服务，并共享该报表，以便 Power BI 服务和移动设备上的业务用户可以查看该报表并与之交互。

This workflow is common, and shows how the three main Power BI elements complement one another.
此工作流很常见，并显示了三个主要的 Power BI 元素如何相互补充。

In the Power BI service, you can use the deployment pipeline tool to test your content before you release it to your users. The deployment pipeline tool can help you deploy reports, dashboards, semantic models, and paginated reports. Read about how to get started with deployment pipelines in the Power BI service.
在 Power BI 服务中，您可以使用部署管道工具在将内容发布给用户之前对其进行测试。部署管道工具可以帮助您部署报表、控制面板、语义模型和分页报表。了解如何在 Power BI 服务中开始使用部署管道。

Microsoft Fabric is an offering that combines data + services in a unified environment, making it easier to perform analysis and analytics on various sets of data. Power BI is an example of one of the services that's integrated with Microsoft Fabric, and your organization's OneLake data store is an example of the data that can be used, analyzed, or visualized. Large organizations find Microsoft Fabric particularly useful, since it can corral and then bring greater value to large stores of data, then using services (like Power BI) to bring such data to business life.

Administration of Power BI is now handled by Microsoft Fabric, but your favorite tools like the Power BI service and Power BI Desktop still operate like they always have - as a service that can turn your data, whether in OneLake or in Excel, into powerful business intelligence insights.

Another workflow involves paginated reports in the Power BI service. Enterprise report creators design paginated reports to be printed or shared. They can also share these reports in the Power BI service. They're called paginated because they're formatted to fit well on a page. They're often used for operational reports, or for printing forms such as invoices or transcripts. They display all the data in a table, even if the table spans multiple pages. Power BI Report Builder is the standalone tool for authoring paginated reports.

What if you need to keep your reports on premises, say, behind a firewall? Read on.

You can create, deploy, and manage Power BI reports in Power BI Desktop, and paginated reports in Report Builder, with the ready-to-use tools and services that Power BI Report Server provides.

Power BI Report Server is a solution that you deploy behind your firewall and then deliver your reports to the right users in different ways, whether that's viewing them in a web browser, on a mobile device, or as an email. And because Power BI Report Server is compatible with Power BI in the cloud, you can move to the cloud when you're ready.
