Create and use dataflows in Microsoft Power Platform
Using dataflows with Microsoft Power Platform makes data preparation easier, and lets you reuse your data preparation work in subsequent reports, apps, and models.
In the world of ever-expanding data, data preparation can be difficult and expensive, consuming as much as 60 to 80 percent of the time and cost for a typical analytics project. Such projects can require wrangling fragmented and incomplete data, complex system integration, data with structural inconsistency, and a high skillset barrier.
To make data preparation easier and to help you get more value out of your data, Power Query and Power Platform dataflows were created.
With dataflows, Microsoft brings the self-service data preparation capabilities of Power Query into the Power BI and Power Apps online services, and expands existing capabilities in the following ways:
Self-service data prep for big data with dataflows: Dataflows can be used to easily ingest, cleanse, transform, integrate, enrich, and schematize data from a large and ever-growing array of transactional and observational sources, encompassing all data preparation logic. Previously, extract, transform, load (ETL) logic could only be included within datasets in Power BI, copied over and over between datasets, and bound to dataset management settings.
With dataflows, ETL logic is elevated to a first-class artifact within Microsoft Power Platform services, and includes dedicated authoring and management experiences. Business analysts, BI professionals, and data scientists can use dataflows to handle the most complex data preparation challenges and build on each other's work, thanks to a revolutionary model-driven calculation engine, which takes care of all the transformation and dependency logic—cutting time, cost, and expertise to a fraction of what's traditionally been required for those tasks. You can create dataflows by using the well-known, self-service data preparation experience of Power Query. Dataflows are created and easily managed in app workspaces or environments, in Power BI or Power Apps, respectively, enjoying all the capabilities these services have to offer, such as permission management and scheduled refreshes.
Load data to Dataverse or Azure Data Lake Storage: Depending on your use case, you can store data prepared by Power Platform dataflows in the Dataverse or your organization's Azure Data Lake Storage account:
Dataverse lets you securely store and manage data that's used by business applications. Data within Dataverse is stored in a set of tables. A table is a set of rows (formerly referred to as records) and columns (formerly referred to as fields/attributes). Each column in the table is designed to store a certain type of data, for example, name, age, salary, and so on. Dataverse includes a base set of standard tables that cover typical scenarios, but you can also create custom tables specific to your organization and populate them with data by using dataflows. App makers can then use Power Apps and Power Automate to build rich applications that use this data.
Azure Data Lake Storage lets you collaborate with people in your organization using Power BI, Azure Data, and AI services, or using custom-built Line of Business Applications that read data from the lake. Dataflows that load data to an Azure Data Lake Storage 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.
Advanced Analytics and AI with Azure: Power Platform dataflows store data in Dataverse or Azure Data Lake Storage—which means that data ingested through dataflows is now available to data engineers and data scientists to leverage the full power of Azure Data Services, such as Azure Machine Learning, Azure Databricks, and Azure SQL Data Warehouse for advanced analytics and AI. This enables business analysts, data engineers, and data scientists to collaborate on the same data within their organization.
Support for Common Data Model: Common Data Model is a set of a standardized data schemas and a metadata system to allow consistency of data and its meaning across applications and business processes. Dataflows support Common Data Model by offering easy mapping from any data in any shape into the standard Common Data Model entities, such as Account and Contact. Dataflows also land the data, both standard and custom entities, in schematized Common Data Model form. Business analysts can take advantage of the standard schema and its semantic consistency, or customize their entities based on their unique needs. Common Data Model continues to evolve as part of the Open Data Initiative.
