自动生成应用Generate an app automatically

在 PowerApps 中自动生成应用很容易。It's easy to automatically generate an app in PowerApps. 只需指定所需的数据来源即可。All you need to do is specify where you want your data to come from. 数据存储在数据源中,可以使用各种数据源中的数据。Data is stored in a data source, and you can use data from a variety of data sources. 下面是一些常见数据源:Here are some common ones:

  • Common Data Service(PowerApps 随附)- 一种功能非常强大的业务数据存储方式Common Data Service (included with PowerApps) - a powerful way to store your business data

还可以通过模板自动生成应用。You can also generate an app automatically from a template. 每个模板都基于云帐户(如 Dropbox)中的虚拟数据。Each template is based on fictitious data in a cloud account, such as Dropbox. 请浏览具体屏幕和 UI 元素(称为控件),了解它们的配置方式,并尝试各种自定义,以发现可应用于自己应用的技术。Explore specific screens and UI elements (called controls) to understand how they're configured, and experiment with customization to discover techniques that you can apply to your own apps.

从头开始创建应用Create an app from scratch

自动生成一个或两个应用并积累一定自定义经验后,就可以从头开始创建应用了。After you've generated an app or two automatically and gained some experience with customization, you can create an app from scratch. 从头开始创建应用,不仅可以灵活地处理应用设计、流程和控件,还可以纳入各种数据源。By working from the ground up, you gain flexibility in app design, flow, and controls, and you can incorporate a larger variety of data sources.

共享和运行应用Share and run an app

完成应用并将它保存到云中后,便可以与组织中的其他人共享它。When you finish your app and save it to the cloud, you can then share it with others in your organization. 可以控制应用的权限级别,即决定哪些用户或组可以运行应用,以及他们是否还能自定义应用或与组织中的其他人共享应用。You control the level of permissions on your app - you decide which users or groups can run the app, and whether they can also customize it or share it with additional people in the organization.

可以在 Windows、iOS、Android 或 Web 浏览器中运行自己的应用,以及其他人与你共享的任何应用。You can run your own apps - and any apps shared with you - on Windows, iOS, Android, or in a web browser.
