Self-service data prep with dataflows
As the volume of data continues to grow, so does the challenge of shaping that data into well-structured, actionable information. You want data that’s ready for apps, AI workloads, or analytics so that you can quickly turn volumes of data into actionable insights. With self-service data prep in the Power Apps portal, you can transform and load data to Microsoft Dataverse or your organization’s Azure Data Lake Storage Gen2 account with just a few clicks.
Dataflows were introduced to help organizations unify data from disparate sources and prepare it for consumption. You can easily create dataflows using familiar, self-service tools to ingest, transform, integrate, and enrich big data. When creating a dataflow, you will define data source connections, ETL (extract, transform, load) logic, and destination to load the resulting data to. Once created, you can configure a dataflow's refresh schedule to indicate how frequently it should run. In addition, the new model-driven calculation engine makes the process of data preparation more manageable, more deterministic, and less cumbersome for dataflow customers. With dataflows, tasks that once required a data IT organization to create and oversee (and many hours or days to complete) can now be handled with a few clicks by individuals who aren’t even data scientists, such as app creators, business analysts and report creators.
Dataflows store data in tables. An table is a set of rows used to store data, similar to how a table stores data within a database. Customers can define custom table schema or leverage the Common Data Model’s standard tables. The Common Data Model is a shared data language for business and analytical applications to use. The Common Data Model metadata system enables consistency of data and its meaning across applications and business processes such as Power Apps, Power BI, some Dynamics 365 apps (model-driven apps), and Azure, which store data in conformance with the Common Data Model. A dataflow’s resulting tables can then be stored in either of the following:
Dataverse. Lets you securely store and manage data that's used by business applications built using Power Apps and Power Automate.
Azure Data Lake Storage Gen2. Lets you collaborate with people in your organization using Power BI, Azure Data, and AI services or custom-built line-of-business applications that read data from the lake. Dataflows that load data to an Azure Data Lake Storage Gen2 account store data in Common Data Model folders. Common Data Model folders contain schematized data and metadata in a standardized format to facilitate data exchange and to enable full interoperability across services that produce or consume data stored in an organization’s Azure Data Lake Storage account as the shared storage layer.
You can use dataflows to ingest data from a large and growing set of supported on-premises and cloud-based data sources including Excel, Azure SQL Database, SharePoint, Azure Data Explorer, Salesforce, Oracle database, and more.
After selecting the data source, you can use the Power Query low-code/no-code experience to transform the data and map it to standard tables in the Common Data Model or create custom tables. Advanced users can directly edit a dataflow’s M-language to fully customize dataflows, similar to the Power Query experience that millions of Power BI Desktop and Excel users already know.
Once you’ve created and saved a dataflow, you will need to run it in the cloud. You can choose to trigger a dataflow to run manually or schedule the frequency for the Power Platform Dataflow service to run it for you. When a dataflow completes a run, its data is available to use. To get dataflow data loaded into Dataverse, the Common Data Service connector can be used in Power Apps, Power Automate, Excel, and all other applications that support the Dataverse connector. To get from dataflows stored in your organization’s Azure Data Lake Storage Gen2 account, you can used the Power Platform Dataflow connector in Power BI Desktop or access the files directly in the lake.
How to use dataflows
The previous section provided background on dataflows technology. In this section, you get a tour of how dataflows can be used in an organization.
You must have a paid Power Apps plan to use dataflows, but you are not charged separately for using dataflows.
Load data to Dataverse
Dataflows can be used to populate tables in the Common Data Service that are then used in Power Apps applications. With a few clicks, you can integrate data from online and on-premises data sources.
Extend the Common Data Model for your business needs
For organizations that want to extend and build upon the Common Data Model, dataflows enable business intelligence professionals to customize the standard tables or create new ones. This self-service approach to customizing the data model can then be used with dataflows to build Power BI dashboards that are tailored to an organization.
Extend your capabilities with Azure Data and AI services
Power Platform dataflows can be configured to store dataflow data in your organization’s Azure Data Lake Storage Gen2 account. When an environment is connected to your organization's data lake, data scientists and developers can leverage powerful Azure products such as Azure Machine Learning, Azure Databricks, Azure Data Factory, and more.

Summary of self-service data prep for big data in Power Apps
There are multiple scenarios and examples where dataflows can enable you to get better control—and faster insights—from your business data. Other people in your organization can leverage dataflows either via Dataverse, the Power Platform Dataflow connector in Power BI, or via direct access to Dataflow’s Common Data Service folder in your organization’s Azure Data Lake Storage Gen2 account. Using a standard data model (schema) defined by the Common Data Model, business applications can depend on a table’s schema, and be abstracted from how the data was created or from which data source. When a dataflow completes a scheduled run, the data is ready for modeling and creation of apps, flows, or BI insights in a very short period... in what used to take months, or longer, to create.
The standardized format of the Common Data Model allows people in your organization to create apps that generate quick, easy, and automatic visuals and reports. Those include, but aren’t limited to:
Mapping your data from various sources to standard tables in the Common Data Model to unify data and leverage the known schema to drive out-of-the-box applications.
Creating your own custom tables to unify data across your organization.
Creating Power BI reports and dashboards that leverage dataflow data.
Creating integration with Azure Data and AI services via your organization’s Azure Data Lake Storage Gen2 account.
