Know About Power BI Datamarts

By Ryan Freeman

July 4, 2022


Power BI Datamarts were first announced during Microsoft Build 2022. Datamarts are an exciting new feature which is available to preview and enables self-service users to build and distribute an analytical solution from end-to-end. This includes data ingestion, preparation, exploration, analysis, data modelling, and report design which can all be completed in Power BI Service – crucially with little or no coding.

What is Power BI?

Microsoft Power BI (Business Intelligence) is used to find insights into an organisation’s data. Power BI can be used to connect to data sets from multiple sources, transform and clean the data into a data model and create interactive visualisations which bring to life the organisation’s data. The data can then be easily sliced and diced by the user to find new insight.

What is a Data Mart?

A data mart is a subject specific data warehouse, often containing data related to one domain or line of business within an organisation. A data warehouse can contain complex structures such as slowly changing dimensions which are not simple structures for business users.

A data mart however is a more focussed and friendly set of data that can be understood and used by business users.

Power BI Datamarts

Power BI Premium users can create their own datamarts which puts the power firmly in their hands. Instead of waiting for other data team members like Database Administrators, Data Engineers and Data Analytics to assist, these business users can use Power Query to load data from multiple sources into the Power BI Datamart.

Behind the scenes the data mart is an automatically provisioned Azure SQL database and once the data is loaded, the user can define relationships, write measures, protect the data with Row-Level Security roles, etc.

Use cases for Power BI Datamarts


• When you do not want to make changes to the enterprise data warehouse but need to add additional data e.g., for forecasting.
• When you want to manipulate data visually or through expressions defined in SQL.
• For outputs that are results, sets, tables, and filtered tables of data.
• Provide accessible data through a SQL endpoint.
• Enable users who don’t have access to Power BI Desktop.
