This document provides an overview of Power BI and its capabilities for data analytics. Power BI allows users to analyze data and share insights across devices. It connects to various data sources and allows users to clean, transform and visualize data through reports and dashboards. Examples shown include visualizing diamond data and using algorithms for classification, prediction and other tasks. Power BI provides tools for business users to gain insights from metrics in a centralized location.

Editor's Notes
- #6: Power BI can unify all of your organization’s data, whether in the cloud or on-premises. Using the Power BI gateways, you can connect SQL Server databases, Analysis Services models, and many other data sources to your same dashboards in Power BI. If you already have reporting portals or applications, you can embed Power BI reports and dashboards into web and app scenarios for a unified experience across any device or platform.
- #10: The basic building block for all Business Intelligence elements in Power BI begins with the data itself. Data from various sources is filtered, cleaned, and combined into Reports via Visualizations, and optionally published to Dashboards. Dashboard data is surfaced to users on any device, based on permissions and organization needs.
- #18: A primary goal of Microsoft Power BI is to enable report creators, managers, and stakeholders to connect to any data source necessary to create a unified experience that makes sense to audiences and viewers of the content. Along with full support for more typical, legacy systems such as an Excel spreadsheet or SQL Server database, Power BI can authenticate and access data across a wide variety of data sources via “Connectors”, including Azure, Oracle, or even external services such as Facebook, Salesforce, or MailChimp,
- #24: cluster
- #25: Reinforcement learning
- #27: Visualizations or “Visuals” are the end-result of any Business Intelligence effort. Ultimately, the aim is to access data, any data that makes sense in our organization, and present it to users in a meaningful, compelling, interactive, and insightful way. Power BI exposes a large number of out-of-the-box visualizations found in common Business Intelligence tools, such as numerous graphs, charts, maps, and filters, while also enabling visualization “extensibility” for creating organization-specific or scenario-specific custom visuals to be created by developers and power users.
- #53: Built into the Power BI experience is the ability for users to glean additional information “on-the-fly” via a natural language question and answer paradigm, as well as providing quick “insights” into a dashboard, report, or the associated data based on intelligent analysis of current datasets. Power BI makes it easy to access these features by keeping the front and center during the user experience.
