Power BI vs Tableau: Which BI Tool is Right for You?
Ease of Use – Power BI is more beginner-friendly, especially for those familiar with Excel, while Tableau requires a steeper learning curve but offers advanced customization.
Pricing – Power BI is more affordable, making it ideal for small businesses, whereas Tableau is costlier but provides robust enterprise-level features.
Data Connectivity – Both tools support various data sources, but Tableau offers broader and deeper connectivity options for large-scale data analytics.
Visualization & Customization – Tableau excels in advanced visualizations and design flexibility, whereas Power BI provides a simpler drag-and-drop interface with strong AI-driven insights.
Performance & Speed – Tableau handles large datasets more efficiently, whereas Power BI can slow down with very complex models unless optimized.
Integration – Power BI integrates seamlessly with Microsoft products (Excel, Azure, Power Apps), while Tableau connects well with multiple platforms, including cloud services.
Community & Support – Tableau has a strong user community for data visualization, while Power BI benefits from Microsoft’s extensive support and frequent updates.

Custom Column in Power BI :
- A custom column in Power BI is a new column created by applying formulas, calculations, or logic on existing columns. It allows you to modify and enhance your dataset within the Power Query Editor before loading the data into Power BI reports.
- Unlike calculated columns, which are created in the Data Model using DAX, custom columns are created using Power Query M Language and provide more flexibility in data transformation.

Data modeling in Power BI:
- Connect to data sources and use Power Query to clean and prepare data for analysis.
- Establish relationships between tables using primary and foreign keys to allow data from different tables to be combined effectively.
- Visualize and manage the data model in the Diagram View to define and edit relationships.
- Use DAX to create calculated columns for row-level calculations and measures for aggregations and dynamic calculations.
- Create hierarchies within tables to enable drill-down capabilities in reports.

What is Import Mode in Power BI?
Import Mode in Power BI refers to the method where data from different sources (Excel, SQL Server, SharePoint, etc.) is imported and stored within Power BI’s in-memory storage. This means that when you choose to import data, Power BI creates a snapshot of the data from the source and stores it in its internal memory for fast access during analysis.

Page Filter In Power BI :
A Page Filter is a filter that applies to an entire page in a Power BI report. When you add a Page Filter, all the visuals on that page display data based on the selected filter criteria. However, this filter does not impact other pages of the report, making it a great way to create focused views of data without affecting the overall report.

- A hierarchy is used to present data in a structured and ordered manner. It is particularly useful when you want to drill down into data at various levels, such as year, month, and day.
- Hierarchies make your data model easier to understand and enhance the interactivity of reports.

Best Practices for Using Power Query Editor :
To make the most out of Power Query Editor, follow these best practices:
1. Remove Unnecessary Columns
Keep only the columns you need to reduce file size and improve performance.
2. Apply Filters at the Earliest Stage
Filtering early reduces the data load, making queries run faster.
3. Use Merge Queries Instead of VLOOKUP
If you need data from another table, use Merge Queries instead of writing complex DAX formulas.
4. Keep Applied Steps Organized
Rename steps for better readability and avoid unnecessary transformations.
5. Enable Query Folding for Performance Optimization
Query Folding allows Power Query to push transformations to the data source, improving performance.

What is a Histogram in Power BI?
- A histogram is a powerful visualization tool in Power BI that helps analyze data distribution by grouping values into defined intervals or bins. Unlike a bar chart, which compares categories, a histogram focuses on how frequently data points fall within specific numeric ranges.
- A histogram is a type of bar chart that visualizes the frequency distribution of numerical data by grouping values into bins (ranges). It helps businesses analyze trends, detect outliers, and make informed decisions.
