These dashboards can be printed or shared using Power BI services. 

2. Smart Dataset Filtering 

Using Power BI massive datasets can be filtered to zoom in on the stuff we want to refer to. It’s like focusing on specific data without drowning in the entire sea of information.

3. Data Connectivity

To analyze data, we first need the connectivity of different data sources. Power BI supports diverse data sources; including databases (SQL Server, Oracle), cloud services (Azure, AWS), online services (Google Analytics, Facebook), and local files (Excel, CSV).

4. Data Modeling

Once various data sources are connected to Power BI, the importance of data modeling can’t be overstated as it forms the foundation; establishing relationships between different data tables, and improving data quality and well-structured data contributes to better query performance. 

5. Explore Data

Power BI’s drill-down functionality allows users to seamlessly explore data from high-level summaries down to granular transaction details. This hierarchical navigation provides transparency into the intricacies of the data, fostering a dynamic and interactive reporting experience. With customizable detail views, users can tailor their analyses, making Power BI a powerful tool for in-depth data exploration and insight generation.

8. The Statistical Language R

Power BI supports widely used Statistical Language R., Data Analytics is not just representing data in charts and table format. Statistical models can recognize patterns within datasets and can predict or forecast based on historical data. Statistical models also help in Hypothesis testing, risk management, decision support, segmentation & targeting, along machine learning.
