课程名称：Microsoft Fabric：Power BI的直接湖和语义链接 概述：Microsoft Fabric 是未来数据分析的统一平台，提供全面的数据移动、数据湖、数据工程、数据集成、数据科学、实时分析和商业智能服务。它建立在 Power BI 服务平台之上，为所有数据提供单一的真相来源，从而使组织能够更快地做出更好的决策。Microsoft Fabric 旨在帮助各类组织克服大数据分析中的挑战，如数据孤岛、数据复杂性和数据安全。该平台使用户可以轻松地实时收集、存储、处理和分析来自任何来源的数据。 Power BI 是一款商业智能（BI）和数据可视化工具，帮助用户将数据转化为可操作的洞察。通过连接、清理和准备数据，创建并分享报告和仪表板，用户可以更有意义地与数据互动。Power BI 使用简单、价格合理，并且具有良好的可扩展性，适合各类企业使用，与 Microsoft Fabric 紧密集成。 Direct Lake 是 Microsoft Fabric 的一项新功能，对 Power BI 开发者来说是一个颠覆性的改变。它消除了传统导入模式数据集的需求，同时保持与导入模式数据集相同的性能。Direct Lake 的优势包括： - 提升性能：Direct Lake 提供与导入模式相似的性能，即使对于非常大的数据集。 - 降低延迟：用户可以立即在报告和仪表板中查看最新数据，无需数据集刷新的步骤。 - 提高可扩展性：在分析非常大的数据集时，无需担心性能或扩展性问题。 - 简化数据管理：无需导入或刷新数据集，简化了 Power BI 的数据管理。 - 降低成本：通过消除对存储导入数据的需求，Direct Lake 可以帮助降低 Power BI 成本。 语义链接是 Microsoft Fabric 中的一项功能，允许用户将 Power BI 数据集与 Synapse 数据科学连接。数据科学家、数据分析师和 BI 开发者能够直接在 Fabric 笔记本中访问和分析 Power BI 数据，使用如 Pandas 和 Spark 的流行工具和库。语义链接还将语义信息从 Power BI 传播到 Fabric，增强数据科学任务的能力，如数据增强、验证和探索。 数据激活器是 Microsoft Fabric 中的零代码体验，使 BI 开发者能够根据 Power BI 数据自动驱动行动。它监控 Power BI 报告中的数据，当数据达到特定阈值或匹配其他模式时，自动采取适当措施，如提醒用户或启动 Power Automate 流程。其功能包括： - 在关键指标上升或下降到某些阈值时提醒用户 - 当新数据可用时自动发送通知 - 触发工作流程以自动化数据准备、模型训练和报告生成等任务 本课程将帮助用户深入了解 Microsoft Fabric 的功能与应用，提升数据分析与决策的效率和准确性。
Microsoft Fabric is the future of data analytics and is a unified analytics platform that provides a comprehensive set of services for data movement, data lakes, data engineering, data integration, data science, real-time analytics, and business intelligence. It is built on the Power BI Service platform and offers a single location and source of truth for all data, enabling organizations to make better decisions faster.Microsoft Fabric is designed to help organizations of all sizes overcome the challenges of big data analytics, such as data silos, data complexity, and data security. It provides a unified platform that makes it easy to collect, store, process, and analyze data from any source, in real time.Power BI is a business intelligence (BI) and data visualization tool that helps people turn their data into actionable insights. It provides a variety of features to help users connect to data, clean and prepare data, create and share reports and dashboards, and interact with data in a meaningful way.Power BI is a popular choice for BI because it is easy to use, affordable, and scalable. It can be used by businesses of all sizes, from small businesses to large enterprises. It is tightly integrated into Microsoft Fabric.Direct Lake is a new feature in Microsoft Fabric and it is a game changer for Power BI developers. It eliminates the need for traditional Import mode datasets in Power BI but, yet, maintains the same performance level of import mode datasets. It offers:Improved performance: Direct Lake provides similar performance to Import mode, even for very large datasets. This is because Direct Lake loads data on-demand (on-demand loading) from the data lakehouse, rather than importing it into Power BI.Reduced latency: Direct Lake eliminates the need for dataset refreshes, so users can see the latest data in their reports and dashboards immediately.Increased scalability: Direct Lake allows users to analyze very large datasets in Power BI without having to worry about performance or scalability issues.Simplified data management: Direct Lake makes it easier to manage data in Power BI, as there is no need to import or refresh datasets.Reduced costs: Direct Lake can help to reduce Power BI costs by eliminating the need to store imported data.Semantic Link is a feature in Microsoft Fabric that enables users to connect Power BI datasets with Synapse Data Science. This allows data scientists, data analysts and BI developers to access and analyze Power BI data directly from within their Fabric notebooks, using popular tools and libraries such as Pandas and Spark.Semantic Link also propagates semantic information from Power BI to Fabric, which can be used to enhance data science tasks such as data augmentation, validation, and exploration.Data Activator is a no-code experience in Microsoft Fabric that empowers BI developers to drive actions automatically from their Power BI data. It monitors data in Power BI reports (or Eventstreams items), for when the data hits certain thresholds or matches other patterns. It then automatically takes appropriate action such as alerting users or kicking off Power Automate flows. It offers:Alerting users when key metrics go above or below certain thresholdsAutomatically sending notifications when new data is availableTriggering workflows to automate tasks such as data preparation, model training, and report generation
