Data Extract, Transform, and Load in Power BI

Microsoft concentrates on the preparation stage of a Power BI workflow. Data connections lead into transformations and advanced ETL, followed by assessment. It is a focused foundation for learners who need to make source records consistent before creating models or dashboards.

What you will learn

• Connect Power BI to a data source.
• Transform records into a usable structure.
• Explain more advanced extract, transform and load operations.

Who this suits

Beginners interested in analytics and technology; an IT background is unnecessary.

Before you enroll

Check access to the exercise sources and Power BI environment. Preserve a way to inspect the original records so transformation errors can be traced.

Coursera offers paid enrollment or subscription access. Check the enrollment screen for assessment and certificate terms, trials and any financial-aid options. Provider access terms can change; review them before paying.

Put it into practice

Prepare two fictional files with inconsistent column types. Document the transformations and compare row counts and missing values before and after loading.
