Power BI Concepts You Must Know
To begin with Power BI, it’s important to understand key concepts.
1) Reports vs Dashboards
A report in Power BI is a multi-page visualization built using Power BI Desktop. A dashboard, on the other hand, is a single-page canvas in the Power BI Service that aggregates visuals from one or more reports.
2) Datasets, Visuals, and Workspaces
A dataset is the underlying data model. Visuals are the charts and tables displayed in your report. A workspace is a collaborative environment in the Power BI Service where reports and dashboards are published and managed.
3) Data Modeling in Power BI
Data models are built by connecting multiple tables using relationships (like primary and foreign keys). Common schemas include star schema and snowflake schema. Good modeling improves performance and report accuracy.
