What is power query D365 ?

Power Query is a data transformation and data preparation engine. Power Query comes with a graphical interface for getting data from sources and a Power Query Editor for applying transformations. Because the engine is available in many products and services, the destination where the data will be stored depends on where Power Query was used. Using Power Query, you can perform the extract, transform, and load (ETL) processing of data.





How Power Query helps with data acquisition

Business users spend up to 80 percent of their time on data preparation, which delays the work of analysis and decision-making. Several challenges contribute to this situation, and Power Query helps address many of them.

Existing challengeHow does Power Query help?
Finding and connecting to data is too difficultPower Query enables connectivity to a wide range of data sources, including data of all sizes and shapes.
Experiences for data connectivity are too fragmentedConsistency of experience, and parity of query capabilities over all data sources.
Data often needs to be reshaped before consumptionHighly interactive and intuitive experience for rapidly and iteratively building queries over any data source, of any size.
Any shaping is one-off and not repeatableWhen using Power Query to access and transform data, you define a repeatable process (query) that can be easily refreshed in the future to get up-to-date data.
In the event that you need to modify the process or query to account for underlying data or schema changes, you can use the same interactive and intuitive experience you used when you initially defined the query.
Volume (data sizes), velocity (rate of change), and variety (breadth of data sources and data shapes)Power Query offers the ability to work against a subset of the entire dataset to define the required data transformations, allowing you to easily filter down and transform your data to a manageable size.
Power Query queries can be refreshed manually or by taking advantage of scheduled refresh capabilities in specific products (such as Power BI) or even programmatically (by using the Excel object model).
Because Power Query provides connectivity to hundreds of data sources and over 350 different types of data transformations for each of these sources, you can work with data from any source and in any shape.

Power Query experiences

The Power Query user experience is provided through the Power Query Editor user interface. The goal of this interface is to help you apply the transformations you need simply by interacting with a user-friendly set of ribbons, menus, buttons, and other interactive components.

The Power Query Editor is the primary data preparation experience, where you can connect to a wide range of data sources and apply hundreds of different data transformations by previewing data and selecting transformations from the UI. These data transformation capabilities are common across all data sources, whatever the underlying data source limitations.

When you create a new transformation step by interacting with the components of the Power Query interface, Power Query automatically creates the M code required to do the transformation so you don't need to write any code.

Currently, two Power Query experiences are available:

  • Power Query Online—Found in integrations such as Power BI dataflows, Microsoft Power Platform dataflows, Azure Data Factory wrangling dataflows, and many more that provide the experience through an online webpage.
  • Power Query for Desktop—Found in integrations such as Power Query for Excel and Power BI Desktop.

Power Automate compose vs variable

  Variable Compose Variables hold different types of data types like string, boolean array, etc, to validate what we give in terms of our data. If the data doesn’t match the data types it will give an error. Compose action is typeless, which means it is very flexible, we can provide any type of data(we can give XML, JSON, etc) as an input. Variables can be set many times, which means we can set it, reset it at any point of our flow, as per our requirement. Compose only set once, which means compose doesn’t have the update function It can be grouped together under the variable heading, which means when we access the variable from the dynamic content. It was very clearly visible in the dynamic content because we can see the name of a variable, and also make it easy to identify what the variable is in dynamic content and what variable I want to use. Compose are not grouped, which means we give some data as input and it will return some data as output. So in dynamic content, we can onl...
