Datamart is one of the newest addition to the Power BI component. It helps to bridge the gap between business users and IT. It provides an easy and no-code experience to ingest data from different data sources and perform ETL on the data using Power Query. After that, we can load the data to an Azure SQL database which is fully managed and doesn’t require tuning or optimization.

Datamart also provides a single platform to carry out all these processes without needing an extra tool, so we have our Dataflow, Azure SQL Database, Power BI Dataset, and a Web UI all in one place.

The people who use Datamart consist of  Data Analysts, Developers, and Business owners.

 

Let’s discuss the features and benefits of Datamart.

Features of Datamart in Power BI

a)The Datamart tool has an automated performance tuning and optimization whereby you don’t need to do the tuning yourself.

b)It is also a 100% web-based tool that requires no extra software.

c) Datamart has a native integration with Power BI and other Microsoft analytics software.

d)It has a friendly user interface. It requires no coding experience to use it.

e)DataMart is supported to use with SQL and other in-demand client tools.

 

Benefits of DataMart

a)Datamart is very efficient in data ingestion and performing Extraction, transformation, and loading of data with SQL

b)To use Datamart, you don’t have to be a programmer.

c)Datamart also provides self-service users to carry out relational database analytics without the aid of a database administrator.

d)Datamart enable Power BI users to build end-to-end solutions without dependencies on other tooling or IT teams.

e) Datamart provides a centralized small to moderate data volume (approximately 100 GB)for self-service users.

Comparison Between DataFlow and DataMart

Remember we talked about Power BI DataFlow in our earlier tutorial? We mentioned it’s a data transformation component in Power BI with a Power Query process running in the cloud. It helps store data into CDM(Common Data Model) inside Azure Data Lake storage. Power BI uses these Dataflows to ingest data into our Datamarts. We use dataflows whenever we want to utilize our ETL logic.

When discussing the features, we talked about Datamart. We mentioned it’s a fully managed database that enables us to store our data in a relational managed Azure SQL DB; we also said it’s a no-code visual query designer.

So in DataFlow, we can’t browse tables, query, or explore without providing our dataset, while in Datamart, it is possible to sort, filter, and do simple aggregation through SQL expressions. We also have access to our data via the SQL endpoint.

DataFlow is usually used whenever we want to build reusable and shareable data prep in Power BI.
