Explanation
Power BI dataflows allow users to clean and transform data before loading it into reports and dashboards.
The primary function of a Power BI 'dataflow' is to extract, transform, and load (ETL) data for reporting. Dataflows act as self-service ETL pipelines within the Power BI ecosystem, allowing users to connect to various data sources, clean and transform raw data, and load it into a structured format for use in reports, dashboards, and analytics.
Key capabilities include:
- Extract: Connects to multiple cloud and on-premises data sources to retrieve data.
- Transform: Applies data preparation steps such as filtering, merging, deduplication, and reshaping to ensure data consistency and quality before analysis.
- Load: Stores the transformed data in Power BI or external storage (like Azure Data Lake), making it accessible for building semantic models, reports, and dashboards.
- Centralization and Reusability: Promotes reusable transformation logic and centralized data management, reducing duplication of ETL steps and improving report performance.
- Integration: Dataflows can be used across Power BI, Power Apps, and other Power Platform services, supporting enterprise-wide data integration and analytics.
Power BI dataflows provide a robust ETL layer, enabling users to ingest, clean, and prepare data from diverse sources, ensuring high-quality, centralized data for reporting and analytics across the Power Platform.
