Power Query: Your First Step
Power Query is the tool you use to clean and prepare your data in Power BI. It's often seen as the most complex part, but it's also the most important. Think of it as the kitchen where you prepare your ingredients before cooking.
In Power Query, you can do things like:
- Clean up your data
- Combine information from different files
- Remove extra columns
Merging vs. Appending Tables
A big part of using Power BI is knowing how to join tables together.
- Appending means stacking tables on top of each other (used when tables have the same columns).
- Merging means combining columns from two tables using a common field (like a product ID).
For example, if you have a table of sales and another table of product details, you can merge them using the product ID to see all the information in one place.

Data Modeling: Building Relationships
Once your data is clean, it’s time to build relationships between tables. This is called data modeling.
You’ll work with:
- Fact tables (like sales data)
- Dimension tables (like product or employee information)
To connect these, you use:
- Primary Key: A unique value (like Order ID)
- Secondary Key: A repeated value (like Product ID)
Power BI lets you link these tables so you can create reports that show trends, totals, and comparisons.
Real-World Examples
