Load vs Transform Data

[space83]

What the different between Load and Transform Data?

Which 1 is best to use for direct query method?

Hi @space83 ,

We think there is no best method, only suitable method.

It depends on your requirement.

If you want to create some measures or visuals firstly, you can load the data.

If you want to do some transformations using M query, you can click transform.

But there are some limitations by using Direct Query, so you need to pay attention when you use these two methods.

Please refer this article.

If you use sql database just try Stored procedure to import data. Its more efficent and easy to change.

Load : Load the data into Power BI without making any changes to it.

Transform : Modify the data before loading it into Power BI

When you load data you can use data directly as you import on power bi desktop.

If you use transform you can modify the data you already have or importing data.

Eg:

• change column names
• add columns
• change format etc
