Power Query OverviewSo what exactly is Power Query?What is Power Query?Power Queryis Microsofts Data Connectivity and Data Preparation technology. It basically, enables business users to access data stored in data sources seamlessly whilst, reshaping it to fit their needs. Its easy to use, engaging, even convenient to use for the no-code users.Note: A lot of you might get confused in M and DAX. Let me clarify once and for all that both of them are vastly different from one another. While Mis a mashup querylanguageused to query a multitude of data sources, DAX (or Data Analysis eXpressions) is a formulalanguage which is used to work on data that is stored in tables.Data SourcesSupported data sources include a wide range of file types, databases, Microsoft Azure services, and many other third-party online services. It also provides a Custom Connectors SDK so that third parties can create their own data connectors and seamlessly plug them into Power Query.Power Query EditorThePower Query Editoris the primary data preparation experiencenatively integrated into several Microsoft products, including but not limited to Microsoft Excel, Microsoft Power BI, Microsoft SQL Server Data Tools, etc. This, in turn, allows users to apply over 300 different data transformations by previewing data and selecting transformations in the user experience.These data transformation capabilities are common across all data sources, despite the underlying data source limitations.Power Query in Power BIPower BI Desktop comes equipped with Power Query Editor. You can use the Power Query Editor to connect to one or many data sources, shape and transform the data. You could modify the data in hand to meet your needs, make it more usable, and then load that model into Power BI Desktop.To get to the Query Editor, select Edit Queriesfrom theHome tab of Power BI Desktop. With no data connections, the Query Editor appears quite dull, a blank pane as it should. But once a query is loaded, this Editor view becomes way more interesting. If we connect to a data source, the Query Editor loads information about the data, which you can then begin to shape before basing your model on it.M: Power Query Formula LanguageMicrosoft Power Query provides a powerful data import experience that encompasses many features. Power Query works with Analysis Services, Excel, and Power BI workbooks. A core capability of Power Query is to filter and combine data from a rich collection of data sources that it supports. Any such data mashup is expressed using a functional, case sensitive language known as M Formula Language. It is pretty similar to F# and is used to query a multitude of data sources. It contains commands to transform data and can return the results of the query to either an Excel table or Power BI data model.Quickstart: How to use Power Query in Power BI?Lets get acquainted with theQuery Editor.So, once youve gotten to the query editor, youll have no data connections.
